ABSTRACT:
A thermal fusion type donor film composed of a substratal film and a donor layer superposed on the substratal film, the donor layer comprising a terpolymer produced by polymerization of a reacting composition of 25 to 45% by weight of acrylonitrile, 35 to 55% by weight of n-butyl acrylate, and 10 to 30% by weight of 2-hydroxyethyl methacrylate (these percentages being based on the total amount of monomers) and a coloring material.
The donor film of this invention exhibit an ideal adhesiveness to a substrate of the form of a layer during the manufacture thereof, attains an efficient transfer to an image-receiving layer during the formation of an image, and imparts a gradation to the produced image, and further, is capable of bilevel printing. After the formation of the image is completed, it exhibits very low adhesiveness to other surfaces at normal room temperature.
