Abstract
A dye-fixing element for color diffusion transfer process, having an ultraviolet-absorbing layer that contains an ultraviolet absorber in a coating amount of 0.2 g/m2 or more, over a mordant layer; and containing, as at least one dispersion medium for the ultraviolet absorber, a compound represented by formula (1), in a ratio (mass ratio) of 25 to 200% of the ultraviolet absorber; with the sum of coating amounts of the ultraviolet absorber and total dispersion medium for the ultraviolet absorber being 1.0 g/m2 or less; 1 wherein x and y each represent a molar fraction of each recurring unit, the total of x and y is 1, and y ranges from 0.85 to 0.95.
Claims11
A dye-fixing element for color diffusion transfer process, having an ultraviolet-absorbing layer that contains an ultraviolet absorber in a coating amount of 0.2 g/m2 or more, over a mordant layer;
- and containing, as at least one dispersion medium for the ultraviolet absorber, a compound represented by formula (1), in a ratio (mass ratio) of 25 to 200% of the ultraviolet absorber;
- with the sum of coating amounts of the ultraviolet absorber and total dispersion medium contained for the ultraviolet absorber being 1.0 g/m2 or less;
- 20
- wherein x and y each represent a molar fraction of each recurring unit, the total of x and y is 1, and y ranges from 0.85 to 0.95.
An image-forming method, comprising using a dye-fixing element and a photosensitive element in combination, wherein the dye-fixing element has an ultraviolet-absorbing layer containing an ultraviolet absorber in a coating amount of 0.2 g/m2 or more, over a mordant layer;
- and contains, as at least one dispersion medium for the ultraviolet absorber, a compound represented by formula (1), in a ratio (mass ratio) of 25 to 200% of the ultraviolet absorber;
- with the sum of coating amounts of the ultraviolet absorber and total dispersion medium contained for the ultraviolet absorber being 1.0 g/m2 or less;
- 21
- wherein x and y each represent a molar fraction of each recurring unit, the total of x and y is 1, and y ranges from 0.85 to 0.95.
