摘要:
Polymeric color couplers with repeating units of a polymerized monomer K of formula I ##STR1## with R.sup.1 H or an optionally substituted alkyl group;R.sup.2, R.sup.3, R.sup.4 (identical or different) H, Cl, --COOH or optionally substituted alkyl groups; andX H or a group releaseable by coupling provide, during chromogenic development: magenta dye images with high dye yield and advantageous absorption level.
