Photographic light-sensitive material having a carboxylic acid polymer antistatic layer

Claim 1

A photographic material comprising a support, a light-sensitive silver halide emulsion layer, and an antistatic layer, said antistatic layer containing about 10% to 90% wt% of a water-soluble, film-forming polymer having a carboxylic acid group and about 10 to 90 wt% gelatin, and said layer further containing a carboxylic acid activating condensing agent having the ability to activate a carboxyl group such that it reacts with an alcohol or amine in a condensation reaction, said agent being selected from the group consisting of a compound of the formula (I): ##STR12## wherein R 1 may be any n-valent group; A represents a group of atoms that are bound to the oxygen atom in the formula (I) through a nitrogen atom; and n is an integer of from 1 to 4; a compound of the formula (II): ##STR13## wherein R 2 is an aliphatic group; R 3 is an aliphatic group or an aryl group and the carboxylic acid residue of the formula R 3 --O--CO-- in the formula (II) is such that when it reacts with the carboxylic acid group of gelatin to form a mixed acid anhydride, the electron density on the carbonyl carbon is lower than that of the carboxylic acid group in gelatin; Z represents a group of atoms necessary to form a benzene nucleus, and a compound of the formula (III): ##STR14## wherein R 6 and R 7 are independently an alkyl, allyl or aralkyl group and R 6 and R 7 may combine to form a 5- or 6-membered ring which may contain 1 to 2 hetero atoms other than the nitrogen atom to which R 6 and R 7 are bound; Y is an oxygen atom or sulfur atom; W is an oxygen atom or a single bond; R 8 , R 9 and R 10 are independently a hydrogen atom, an alkyl group of up to 5 carbon atoms, an alkoxy group of up to 4 carbon atoms, an acrylamido group of up to 4 carbon atoms, and a carbamoyl group; X.sup.⊖ is an organic or inorganic acid anion, and X.sup.⊖ is absent from the formula (III) when any of R 6 , R 7 , Y, R 8 , R 9 or R 10 includes a sulfonate anion.
