Color diffusion transfer photosensitive material

Abstract

Disclosed is a color diffusion transfer photosensitive material containing a compound represented by a color diffusion transfer photosensitive material containing at least one compound represented by the following general formula (I): ##STR1## wherein R.sub.1 and R.sub.2 each represent a hydrogen atom, an aliphatic group or an aryl group; and R.sub.3 represents an aliphatic group or a group represented by the following general formula (Ab): ##STR2## wherein R.sub.4 represents a hydrogen atom, an aliphatic group or an aryl group and R.sub.5 represents an aliphatic group, an aryl group or an amino group; and further, R.sub.1 and R.sub.2, R.sub.1 and R.sub.3, R.sub.2 and R.sub.3, or R.sub.4 and R.sub.5 may combine with each other to form a 5- to 7-membered ring, or R.sub.1, R.sub.2 and R.sub.3 may combine with one another to form a bicyclo ring; wherein the total number of carbon atoms contained in R.sub.1, R.sub.2 and R.sub.3 is not smaller than 10, at least either R.sub.1 or R.sub.2 is an aliphatic group, and R.sub.3 is a group represented by general formula (Ab) when one of the groups R.sub.1 and R.sub.2 is an aliphatic group and the other is an aryl group.
