| titleOfInvention | Photographic recording material containing a light-protective agent |
| abstract | 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. <IMAGE> (I) In Formula I, R1 denotes H, a group which can be split off under alkaline conditions, alkyl or aryl; R2 denotes OH, alkyl, aryl, alkoxy or O3H, SO2H, alkyl, aryl, alkoxy, sulphonyl, sulphamoyl, acylamino or <IMAGE> and at least one of the groups R2, R3, R4 R5 and R6 is a group of the formula <IMAGE> A denotes an alkylene group having 1-6 carbon atoms, n stands for 0 or 1, R7 denotes H or an optionally substituted alkyl group, R8 denotes the group of a polymer produced by polycondensation, in particular a polyester, polyether, polycarbonate, polyurethane or polyester polyurethane, R1 and R3 may form a 5-membered or 6-membered ring, in which case R2=OH or alkoxy, and R2 and R4 may form a 5-membered or 6-membered carbocyclic ring. |
