    • Compounds corresponding to Formula I are suitable as light stabilizers for the image dyes produced from colour couplers by chromogenic development. They are also suitable as oil formers for the colour couplers. In a colour photographic recording material, they are preferably used in combination with a pyrazoloazole coupler and associated with a light-sensitive silver halide emulsion layer. ##STR1## In Formula I, R.sup.1 denotes H, a group which can be split off under alkaline conditions, alkyl or aryl;R.sup.2 denotes OH, alkyl, aryl, alkoxy or ##STR2## R.sup.3, R.sup.4, R.sup.5 and R.sup.6 denote H, OH, COOH, SO.sub.3 H, SO.sub.2 H, alkyl, aryl, alkoxy, sulphonyl, sulphamoyl, acylamino or ##STR3## and at least one of the groups R.sup.2, R.sup.3, R.sup.4 R.sup.5 and R.sup.6 is a group of the formula ##STR4## A denotes an alkylene group having 1-6 carbon atoms, n stands for 0 or 1,R.sup.7 denotes H or an optionally substituted alkyl group,R.sup.8 denotes the group of a polymer produced by polycondensation, in particular a polyester, polyether, polycarbonate, polyurethane or polyester polyurethane,R.sup.1 and R.sup.3 may form a 5-membered or 6-membered ring, in which case R.sup.2 =OH or alkoxy, andR.sup.2 and R.sup.4 may form a 5-membered or 6-membered carbocyclic ring.
