Abstract
Polymeric colour-formers useful in photographic materials are prepared by polymerizing at 25-90 DEG C. for 1-36 hours a mixture comprising (i) aqueous gelatin containing 10-90 parts of gelatine; (ii) a solution, in 2 to 60 parts of an addition polymerizable vinyl or a -substituted vinyl compound which is liquid at 50 DEG C., of 3-75 parts of an addition polymerizable monomeric colour-former of the formula CH2 = CR-R1-Q, wherein R is H, C1-C4 alkyl, Cl or Br; R1 is a divalent organic radical and Q is an active colour-former nucleus capable of forming upon chromogenic development of exposed silver halide images with a primary aromatic amine colour-developing agent, a quinoneimine or azomethine dye, said nucleus, in an enol form, containing a group of formula
