ABSTRACT:
An image-receiving element for use in a color diffusion transfer process which comprises a support having thereon an image-receiving layer containing a mordanting polymer having therein a repeating structural unit represented by the following General Formula (I); ##EQU1## wherein each of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is an alkyl group, a hydroxyalkyl group or an aralkyl group, and each of R.sub.1 and R.sub.3 and R.sub.2 and R.sub.4 can combine to form an alkylene group; A is an alkylene group, an arylene group or a group of the formula ##SPC1##
In which m and n each represents 0 or an integer of at least 1, with at least one of m and n being an integer of at least 1; and X.sup.- and Y.sup.- each represents a monovalent anion, and a method for forming a color image in the color diffusion transfer process comprising spreading an alkaline processing solution between an exposed silver halide photosensitive element and the image-receiving element above described.
