| titleOfInvention | Polymeric colour couplers |
| abstract | A polymeric colour coupler of the formula I :-n wherein E′ and E˝ represent the end groups of the polymer chain, R₁ is methyl, hydrogen, chlorine or bromine, R₂ is a divalent organic radical, R¹¹ and R¹¹¹ are each lower alkyl groups having 1 to 6 carbon atoms, or together represent the atoms required to form a five or size-membered heterocyclic ring, R¹ is an alkylene chain or an interrupted alkylene chain, W is the residue of a colour coupler which can react with an oxidised colour developer to yield a dye and B is the residue of an ethylenically unsaturated monomer which comprises no colour coupling residue nor a water solubilising group, a is from 10 to 60% by weight of the polymer, b is from 40 to 90% by weight of the polymer and c is from 0 to 20% by weight of the polymer, at least 10% by weight of the polymer being derived from the monomer which comprises the colour coupler residue and X is an anion. |
