Abstract
Abstract Photographic elements are disclosed containing a hydrophilic colloid layer hardened with a compound having two vinylsulfonyl radicals coupled through a divalent hydrocarbon radical chosen from the group consisting of (1) an aliphatic radical having from 1 to 6 carbon atoms, (2) --X--Y--X-- in which X is an alkylene group having 1 or 2 carbon atoms and Y is a phenylene group and (3) a phenyl-substituted methylene group. The compounds may be utilized generally in hardenable hydrophilic colloid compositions. Except for those compounds incorporating an alkylene divalent hydrocarbon radical, the hardeners are new compounds. .Iadd.
