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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A photographic element comprising a support and at least one radiation-sensitive hydrophilic colloid layer containing silver halide and at least one hydrophilic colloid layer hardened with a compound having two vinylsulfonyl radicals coupled through a divalent hydrocarbon radical chosen from the group consisting of: a. .[.an unsubstituted alkyl or.]. an unsubstituted alkylene radical having from 1 to 6 carbon atoms,   b. --X--Y--X-- in which X is an unsubstituted alkylene group having 1 or 2 carbon atoms and Y is an unsubstituted phenylene group, and   c. phenyl-substituted methylene.   
     
     
       2. A photographic element according to claim 1 in which said layer contains from 0.5 to 6 percent by weight of said hardener based on the weight of hardenable colloid present in said layer. 
     
     
       3. A photographic element according to claim 1 in which said layer contains from 1 to 3 percent by weight of said hardener based on the weight of hardenable colloid present in said layer. 
     
     
       4. A photographic element according to claim 1 in which said layer contains gelatin. 
     
     
       5. A photographic element according to claim 1 in which X is an unsubstituted methylene. 
     
     
       6. A photographic element according to claim 1 in which said hydrophilic colloid is hardened with 1,3-bis(vinylsulfonyl)propane. 
     
     
       7. A photographic element according to claim 1 in which said hydrocarbon radical is an unsubstituted alkylene radical. 
     
     
       8. A photographic element comprising a support and at least one radiation-sensitive silver halide-containing gelatin layer hardened with a compound having the structural formula:   CH.sub.2 =CHSO.sub.2 --A--SO.sub.2 CH=CH.sub.2     in which A is chosen from the group consisting of   a. .[.an unsubstituted alkyl or.]. an unsubstituted alkylene radical having from 1 to 6 carbon atoms;   b. --X--Y--X-- in which X is an unsubstituted alkylene group having 1 or 2 arbon atoms and Y is an unsubstituted phenylene group; and   c. phenyl-substituted methylene. .Iadd. 9. A photographic element comprising a support and at least one radiation-sensitive hydrophilic colloid layer containing silver halide and at least one hydrophilic colloid layer hardened with a compound having two vinylsulfonyl radicals coupled through a divalent hydrocarbon radical chosen from the group consisting of:   a. an unsubstituted alkenylene having from 2 to 6 carbon atoms or an unsubstituted alkylene radical having from 1 to 6 carbon atoms,   b. --X--Y--X-- in which X is an unsubstituted alkylene group having 1 or 2 carbon atoms and Y is an unsubstituted phenylene group, and   c. phenyl-substituted methylene. .Iaddend..Iadd. 10. A photographic element comprising a support and at least one radiation-sensitive silver halide-containing gelatin layer hardened with a compound having the structural formula:   CH.sub.2 =CHSO.sub.2 --A--SO.sub.2 CH=CH.sub.2     in which A is chosen from the group consisting of     a. an unsubstituted alkenylene having from 2 to 6 carbon atoms or an unsubstituted alkylene radical having from 1 to 6 carbon atoms;   b. --X--Y--X-- in which X is an unsubstituted alkylene group having 1 or 2 carbon atoms and Y is an unsubstituted phenylene group; and   
     
     
       c. phenyl-substituted methylene. .Iaddend..Iadd. 11. A photographic element according to claim 9 in which said hydrocarbon radical is an unsubstituted alkenylene radical having from 2 to 6 carbon atoms.
