The vapour pressure of type A dyes increases the most rapidly as the temperature is raised and consequently fixation occurs more rapidly and at lower temperatures with type A dyes than with the other types. The dye is generally applied to the film in solution in the solvent, either at the same time as or subsequently to the swelling treatment. Einige von ihnen sind essenziell, whrend andere uns helfen, diese Website und Ihre Erfahrung zu verbessern. Another known method of dyeing a polyester film with a disperse dye relies upon thermal diffusion of the dye into the film. Weitere Informationen ber die Verwendung Ihrer Daten finden Sie in unserer. This technique can be used to obtain excellent quality film with very few defects. The polyester film is commonly poly(ethylene terephthalate), although other polyesters including polycarbonates may be used. If you are interested, please contact Sales at Fatra: Tel. The heating step is carried out at a temperature below that at which degradation of the film or the dyestuff would occur. A further advantage of the present invention in comparison with solvent dyeing and solvent-assisted dyeing is that, because no swelling agent is required, and because such swelling agents are generally solvents for disperse dyestuffs, as a consequence less dye is washed out of the film in the washing step. If the first surface of the film is dyed with one or more coloured dyestuffs and the second surface id dyed with an ultraviolet absorber as hereinbefore described, it may however be preferred to metallise the first surface of the film. It is known that polyester film containing swelling agent tends to shrink, perhaps by up to 5 or 6%, during heating. The BRY mix used in some of the trials consisted of dyes B and R together with C.I. In a preferred embodiment, at least one of said dyestuffs is an ultraviolet absorber. worldclass facility,pet films,stamping foils for you. Legal notice.

The dye mixtures exhibited viscosity in the range 17.5-23 sec measured using a Number 2 Zahn cup. These films were washed by passage through a single bath of cold water containing a small amount of a non-silicone antifoaming agent. This effect may be advantageous if one or more of the dyes used is sensitive to light, in particular ultraviolet light. Continuous analysis and correction of dye bath composition requires additional specialist apparatus. No. 1 part Dispersol Blue C-3R and 99 parts water were mixed to produce a dye mixture having a viscosity close to that of water (1 centipoise). Even if the dye mixture contains a low level of swelling agent, for example when a liquid disperse dye containing a swelling agent as mentioned above is used, much less swelling agent is present than in prior art solvent dyeing or solvent-assisted dyeing processes. Polyester film was coated with this dye mixture using the same conditions as in Comparative Example 1. The layer is then dried, and the film heated to 200 C. to cause diffusion of the disperse dye from the dye paste into the film. The film may alternatively or additionally be sprayed with water. Coloured polyester films may be readily dyed conventionally with the same dyestuffs to obtain an optical transmission of 20%, and with more difficulty of 5%, but it may be necessary to laminate two or more films together to obtain low values of optical transmission.

SHORT-FORM JUNIOR PATENT SECURITY AGREEMENT;ASSIGNOR:CPFILMS INC.;REEL/FRAME:014718/0276, Free format text: It is an advantage of the invention that low concentrations and amounts of thickener can be used, since the thickener can be washed off the film and discarded after use.

Our PET films offer excellent barrier properties for such environments. It has surprisingly been found that more perfect films having fewer defects can be prepared by the method of the invention than by gravure printing according to the prior art using a high-viscosity dye paste. The other side of the film was coated in similar manner with a dispersion containing 2.7 parts by weight C.I. Coloured polyester film prepared according to the method of the invention may be coated in known manner, for example with a scratch-resistant coating or hardcoat. 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.

This disadvantage can be avoided by the use of the present invention, because the dye mixture can be coated onto the film from a constant composition reservoir. If the coating is applied to the film in a highly uniform manner, then the heating step may be performed under conditions in which essentially all the dyestuff, for example 95% or 98% or more of the dyestuff, migrates from the layer into the film. The film was air-dried, heated at 165 C. for times between 30 seconds and 2 minutes to cause migration of the dyestuff into the film, and washed with water. These twice-treated films exhibited optical transmissions of 25% and 24.5% respectively.

The disperse dyestuff generally penetrates only a relatively small distance into the film in the practice of the process of the invention. The film dyed according to the invention was exposed with either its dyed or its undyed surface towards the light source. (3) heating said film to cause said dyestuff to migrate from said layer into said film. Polyester films are commonly coloured by dyeing with disperse dyes. Preparation of a conventional dye paste having a viscosity of 2000 centipoise or above from disperse dyestuff in powder form may require the use of special mixing apparatus or techniques in order to obtain a homogeneous blend. Average particle size is preferably less than about 1 micron. Disperse Red 60 liquid dyestuff, 0.9 parts by weight C.I.
