ABSTRACT:
A photographic element containing a polymer comprising a recurring unit of general formula (I) and at least one recurring unit selected from the group of units of general formulae (II), (III) and IV) ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represents a hydrogen atom or an alkyl group of 1 to 6 carbon atoms; L represents a divalent linking group of 1 to 20 carbon atoms; and m is 0 or 1; ##STR2## wherein R.sub.1a represents a hydrogen atom or an alkyl group of 1 to 6 carbon atoms; R.sub.4 is an alkyl group, an aryl group or an aralkyl group; and n is 0 or 1; ##STR3## wherein R.sub.1a is as defined in general formula (II); R.sub.5 and R.sub.6 each represents a hydrogen atom or an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and p and q each is equal to 0 or 1; and ##STR4## wherein R.sub.1a is as defined in general formula (II); and D is a divalent linking group necessary for the formation of a 5- to 7-membered ring with the nitrogen atom and carbonyl group.
