  A low molecular weight, film-forming, polymerizable, ethylenically-unsaturated compound is water- and organic solvent-soluble (i.e., soluble in both water and organic solvents) but is readily converted on exposure to actinic radiation to a polymer that is solvent-insoluble (i.e., not soluble in water, organic solvents, or mixtures of water and organic solvents) and, in certain examples, is hydrophobic. The compound comprises the ethylenically-unsaturated derivative (i.e., an ester or an amide) of a sulfopolyol or sulfopolyamine having an ethylenic unsaturated functionality of 2 to 18 and an equivalent weight per ethylenic unsaturated functionality of less than 2500.

  一种低分子量、成膜、可聚合的乙烯基不饱和化合物可溶于水和有机溶剂（即可溶于水和有机溶剂），但在暴露于放热辐射下容易转化为溶剂不溶性（即不溶于水、有机溶剂或水和有机溶剂的混合物）的聚合物，在某些实例中还具有疏水性。该化合物包括乙烯基不饱和衍生物（即酯或酰胺），该衍生物为磺基多元醇或磺基多胺，其乙烯基不饱和官能度为 2 至 18，且每个乙烯基不饱和官能度的当量重量小于 2500。

  Light-sensitive photographic element comprising a polymeric film base, a silver halide emulsion layer, and an antistatic layer comprising a low viscosity and highly sulfonated water soluble polyacetal (preferably obtained by reaction of a low viscosity polyvinyl alcohol and a sulfonated aldehyde), a hydrophobic binder selected from the group consisting of a water dispersible sulfopolyester and a latex polymer having hydrophilic functionality, and a polyfunctional aldehyde crosslinking agent. The antistatic layer may be present as a backing layer on the side of the base opposite the silver halide emulsion layer, as a subbing layer between the base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the base and a different backing layer.
