Photographic element with lactone polymer

摘要

A photographic element comprising a support having thereof at least one silver halide emulsion layer and at least one temporary barrier layer, said temporary barrier layer comprising a mixture of a lactone polymer with repetitive units represented by the formula (I): <IMAGE> Formula (I) and a vinylidene chloride terpolymer represented by the formula (II): <IMAGE> Formula (II) wherein R is a hydrogen atom, an alkyl or an aralkyl group; R1, R2 and R3 each is a hydrogen atom or a methyl group; n1 is an integer of from 1 to 5, while n2 is an integer of 1 or 2; A is a monomer unit of a copolymerizable ethylenically unsaturated acid or of the salt thereof, while B is a copolymerizable ethylenically unsaturated monomer unit; x represents from 50 to 99.5% by weight, y represents from 0.5 to 44.5% by weight, and z represents from 0 to 49.5% by weight.
