The films were then passed through two five foot long ovens heated to 185 C. at 24 ft/min to effect thermosol fixation of the dyestuff from the coating layer into the polyester film. The process can be used to prepare films which contain one or more dyestuffs in one surface region of the film and one or more different dyestuffs, for example an ultraviolet absorber, in the other surface region of the film. Continuous analysis and correction of dye bath composition requires additional specialist apparatus. The amount of harmful light reaching the sensitive dye is thereby reduced to a minimum. The organic liquid may for example be an alcohol, for example ethanol or isopropanol, a ketone, for example acetone or methyl ethyl ketone, or an ester, for example ethyl acetate.

Our long standing experience and competence in the field of manufacturing high quality release papers and films is forming the foundation of our modern and future oriented company. Under such conditions, the washing liquor may be very lightly coloured or nearly colourless. Banding was also more apparent if the doctor blade on the gravure roll was damaged or mounted incorrectly. The results were as follows (delta E, wherein a lower value indicates a lesser change in colour): The film prepared according to the invention therefore showed excellent resistance to weathering when its undyed surface was exposed to the light. Shrinkage in the machine direction was 1.0% for temperatures in the range 160-175 C. and times in the range 10-60 seconds. The dye mixtures were coated onto 24 micron thick biaxially oriented polyester film (supplied by Hoechst Diafoil under the Trade Mark Hostaphan 5211) using a gravure printing machine supplied by Inta Roto, Richmond, Va. Dimensional stability PET films offer excellent resistance to shrinkage, curling or distortion. kilogram approx This information helps us understand how our visitors use our website. It was therefore surprising to find that a wide variety of disperse dyes could be caused to migrate into the film at temperatures at or below the sublimation temperature of the dyestuff. Disperse dyestuffs are commonly classified as type A (having a molecular weight around 250), B, C or D (having a molecular weight around 450). The disperse dyestuff may in general be any disperse dyestuff having substantivity for polyester. This effect was less in those trials where the dye mixture contained IPA. It is an advantage of the invention as compared with transfer printing that diffusion and fixation takes place as contact diffusion through a zero air-gap. The dye mixtures used exhibited a viscosity of around 14 to 17 seconds measured in a Number 2 Zahn cup, well below 500 centipoise. The invention is illustrated by the following Examples, in which all parts, percentages and proportions are by weight unless otherwise specified. Privacy statement SHORT-FORM JUNIOR PATENT SECURITY AGREEMENT;ASSIGNOR:SOLUTIA INC.;REEL/FRAME:014683/0683, Owner name: The sped of the film may be in the range 10 to 500 feet/min, preferably 100 to 200 feet/min. This disadvantage can be overcome by the process of the present invention, since no swelling agent is required. The maximum total solids content of the dye mixture by weight may be up to about 25% and is preferably 20%, more preferably 15%, further preferably 10%. RELEASE OF SECURITY INTEREST RECORDED AT REEL/FRAME;ASSIGNOR:ABLECO FINANCE LLC;REEL/FRAME:020417/0367, Owner name: The dye mixture may optionally additionally comprise an organic liquid which is at least partially miscible with water, and which is miscible with water in the proportion used. Coloured polyester films exhibiting an optical transmission of less than 20%, less than 10%, less than 5% or around 2 % at an absorption maximum of such a dyestuff component can be readily prepared. The highest degree of fixation (that is, the proportion of the dye which diffuses from the layer of paste into the film) is obtained when a heterogeneous dye paste is used, for example by using sodium carboxymethyl starch as thickener or by emulsifying a low boiling point hydrocarbon, for example white spirit, into the dye paste. It may be preferred to precede the water wash by a washing treatment with a water-miscible organic solvent, for example a ketone solvent such as acetone or an amide solvent such as N-methyl-2-pyrrolidinone.

PET color film is made from Special color dyed chips.Can be used for electrical insulation,screen protection, industry adhesive tape, insulation tape,releasing pet film etc applications. The gravure cylinder was driven in the opposite direction to the film web, but not necessarily at the same speed. The invention further provides a process for producing a coloured polyester film, said film having a first and a second surface, including the steps of: (2) coating said dye mixture onto a polyester film to form a layer on said first surface; (3) heating said film to cause said dyestuff to migrate from said layer into said film; and. Very fine streaks, but slight improvement on trial 5. It penetrates into the surface region adjacent to and underlying the coated surface and is substantially all present in this surface region. Tenolan biaxially oriented polyethylene terephthalate (BOPET) films are extruded films with subsequent biaxial orientation. It is an advantage of the present invention that no swelling agent need be present in the dye mixture. RELEASE OF ABL SECURITY INTEREST IN PATENTS - REEL/FRAME 022610/0495;ASSIGNOR:CITIBANK, N.A. The dye mixture may contain a minimum of 0.1%, preferably 0.5%, more preferably 2%, by weight of the dyestuff on a dry weight basis.
The films were then passed through two five foot long ovens heated to 185 C. at 24 ft/min to effect thermosol fixation of the dyestuff from the coating layer into the polyester film. The process can be used to prepare films which contain one or more dyestuffs in one surface region of the film and one or more different dyestuffs, for example an ultraviolet absorber, in the other surface region of the film. Continuous analysis and correction of dye bath composition requires additional specialist apparatus. The amount of harmful light reaching the sensitive dye is thereby reduced to a minimum. The organic liquid may for example be an alcohol, for example ethanol or isopropanol, a ketone, for example acetone or methyl ethyl ketone, or an ester, for example ethyl acetate. Dyes polyester film is often metallised, for example for use in solar control applications. pet metallized film polyester colored larger The coated film was heated to dry the coating layer so formed.

The film may be adhered to the outside or preferably the inside surface of the glass. Shrinkage in the machine direction was greater when the heating step was carried out at higher temperatures and for longer times. The absence or very low level of swelling agent in the dye mixture used in the method of the invention is an advantage in the heating step.
It is sometimes found that the metal does not adhere well or uniformly to the surface of the film during the metallisation process. The presence of excess dyestuff during the heating step assists in providing a level of colouration which is as uniform as possible over the area of the film. Highcombinationwithmultipleresin. The ultraviolet absorber may be incorporated into the film in a number of ways. The film was heated in an oven at 90 C. to dry the dye layer. Manufactured films are thick from 8 m to 150 m.
