A photographic silver halide light-sensitive material having at least one hydrophilic colloid layer containing gelatin and/or a gelatin derivative hardened with a compound represented by the following general formula (I): ##STR1## wherein a and d each represents 1 or 2; b and c each represents 0, 1 or 2 with the proviso that both b and c are not simultaneously 0; R represents a divalent group; and n is 0 or 1, which compound provides a preferred hardening rate and does not adversely affect the photographic properties of photographic light-sensitive materials, and a method of hardening gelatin and/or a gelatin derivative comprising treating the gelatin and/or the gelatin derivative with a compound represented by the general formula (I) above.

Method of hardening gelatin and photographic light-sensitive material

A photographic silver halide light-sensitive material having at least one hydrophilic colloid layer containing (a) gelatin and/or a gelatin derivative and (b) at least one compound represented by the following general formula (I) or (II): ##STR1## wherein Y represents a vinyl group; A represents a divalent group; R, which may be the same or different, each represents a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms; and n is 0 or 1. The compounds of the general formulas (I) and (II) are novel class of gelatin hardeners which are particularly suitable for use in silver halide photographic light-sensitive materials.

Photographic light-sensitive material hardened with a vinylsulfonyl

A method of subbing plastic films, particularly for use in photography, comprising applying an aqueous subbing composition to a surface thereof, the aqueous subbing composition comprising a polymer prepared from 45 to 99.5% by weight of at least one monomer selected from the group consisting of vinylidene chloride and vinyl chloride; 0.1 to 15% by weight of at least one monomer selected from vinyl monomers having one or more alcohol groups in their side chains; and 0 to 54.4% by weight of at least one monomer selected from the group consisting of acrylates, methacrylates, acrylonitrile, methacrylonitrile, alkyl vinyl esters, and alkyl vinyl ethers.
