ABSTRACT:
A color diffusion transfer photographic light-sensitive material is disclosed, said light-sensitive material comprising at least one selected from the group consisting of polymers obtained by the condensation of at least one of compounds represented by the general formula (I) and at least one of compounds represented by the general formula (II) in the presence of an acid or alkaline catalyst; polymers obtained by the condensation of at least one of compounds represented by the general formula (I) and at least one of compounds represented by the general formula (III) in the presence of an acid catalyst; novolak resins obtained by the condensation of at least one of compounds represented by the general formula (I) and at least one of compounds represented by the general formula (IV) in the presence of an acid catalyst in a uniform organic solvent system while eliminating off water produced upon azeotropy; and polymers obtained by the condensation of at least one of compounds represented by the general formula (I) and at least one of compounds represented by the general formula (V) in the presence of an acid catalyst: ##STR1## wherein G represents a hydroxyl group or a group which undergoes hydrolysis by an alkali to produce a hydroxyl group; n represents an integer 1 or more, with the proviso that the plurality of G's may be the same or different; R.sup.1, R.sup.2, R.sup.13, R.sup.14, R.sup.23, R.sup.33, R.sup.43, R.sup.44 and R.sup.45 are defined in the specification.
