Abstract
This invention relates to a method of stabilizing a material for use in a thermal dye transfer imaging process, characterized in that a compound satisfying the formula A-X wherein: A stands for acyl, and X stands for the conjugated base of an acid with a pKa.ltoreq.14, is included in the dye-donor element and/or in the receiving element for use in carrying out said process.
Claims21
Method of stabilizing a material for use in a thermal dye transfer diffusion process, by incorporating a compound satisfying the formula A-X wherein A stands for acyl, and X stands for the conjugated base of an acid with a pKa.ltoreq.14, in a dye layer of a dye-donor element and/or in a receiving layer of a receiving element for use in carrying out said process.
Dye-donor element for use in a thermal dye transfer diffusion process, said element comprising a support sheet which is coated at one side with a layer containing a binder and a thermally transferable dye, said dye layer additionally containing a compound A-X wherein A stands for acyl, and X stands for the conjugated base of an acid with a pKa.ltoreq.14.
Receiving element for use in a thermal dye transfer diffusion process, said element comprising a support sheet which is coated at one side with a dye-image-receiving layer, said dye-image-receiving layer containing a compound A-X wherein A stands for acyl, and X stands for the conjugated base of an acid with a pKa.ltoreq.14.
