Abstract:
A method for forming an image having improved light fastness, which comprises exposing and developing a photosensitive silver halide element containing a diffusible image forming dye or a precursor thereof, and transferring the image forming dye or a precursor thereof to a dye fixing element corresponding or counter-corresponding to silver development and allowing an image formed by transferring said image forming dye or precursor thereof to coexist with a water-soluble compound without a ballast group represented by general formula (I) in said dye fixing element ##STR67## wherein X represents a hydrogen atom, a hydroxyl group, an aliphatic group, an acyl group, an aliphatic oxy group, an aliphatic oxycarbonyl group or an aryloxycarbonyl group, Y.sub.1 and Y.sub.2 may be the same or different from each other, each representing a hydrogen atom or a substituent group, or may form a five- or six-membered nitrogen-containing hetero ring by linking with each other, Z.sub.1 represents a single bond or a methylene or ethylene group which may have a substituent group, Z.sub.2 represents a methylene group which may have a substituent group, and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be the same or different from one another and each represents an aliphatic group wherein each of the combinations of R.sub.1 and R.sub.2 and R.sub.3 and R.sub.4 may form a five- or six-membered ring by linking with each other.
