Japanese Patent JPH0440700

B2

Latexes suited for homogeneously incorporating compounds with a photographically useful group into photographic silver halide emulsion materials. The latex incorporates a copolymer comprising recurring units of a monomer with photographically useful group, and recurring units of surface active monomer, according to the general formula: wherein: R1 is hydrogen or methyl, n is 0 or 1 to 20, L is R2 is hydrogen or a hydrocarbon group, R3 is a monovalent chemical bond or a bivalent aliphatic hydrocarbon group or such group interrupted by the group -COO- or -CONR-, and Y is a sulpho, sulphato or phosphono group in acid or salt form, and at least one of the groups -(CH2)n-, R2 and R3 is or comprises a hydrocarbon chain of at least 8 C-atoms.
