Abstract:
A photographic element, which contains, at least in a binder on a base, at least one compound having a group that is capable of causing chemical reaction with a reactive group contained in the binder, to form a covalent bond, wherein the compound is a compound represented by the following formula (1), (2), or (3): formula (1) ##STR11## wherein the ring structure containing the N represents a nitrogen-containing nonaromatic ring having at least three ring members, X represents a hydrogen atom, an alkoxy group, an aryloxy group, an oxy radical group, a hydroxyl group, or a group capable of forming an imino group or a hydroxyimino group by hydrolysis, and Y represents a group that is capable of causing chemical reaction with a reactive group contained in the binder, to form a covalent bond; ##STR12## wherein X.sup.1 represents a hydrogen atom or a substituent, which substituent may bond to form a ring, n1 is an integer of 1 to 4, Y represents a group that is capable of causing chemical reaction with a reactive group contained in the binder, to form a covalent bond, W represents a divalent linking group, m1 is 0 or 1, and Z represents a group of nonmetallic atoms capable of forming a 5- to 7-membered nitrogen-containing heterocyclic group; formula (3) ##STR13## wherein R.sup.1 represents a hydrogen atom, an alkyl group, an aryl group, or a group capable of forming a hydroxyl group by hydrolysis, n2 is an integer of 1 or more, X.sup.1 represents a hydrogen atom or a substituent, m2 is an integer of 1 or more, with m2+n2 being 5, and Y represents a group that is capable of causing chemical reaction with a reactive group contained in the binder, to form a covalent bond.
