Abstract
A color diffusion transfer film unit and an image formation method using the same are disclosed, in which a light-sensitive material containing a specific sulfonamide compound of formula (I) and a specific tertiary amine compound of formula (II) is processed with an alkali processing composition containing a specific tertiary amine polymer. The film provides a transferred color image having a high density with reduced dependency on processing time, and suppresses changes in density of the resulting image with time after processing.
