发明名称 Color photographic recording material containing a color coupler of the pyrazoloazole series
摘要 Color photographic images having advantageous sensitometric properties, in particular high maximum magenta color density, can be obtained by use of a color photographic recording material containing a pyrazoloazole type magenta coupler of formula I Q-L-COOH I In the formula Q denotes the bicyclic group capable of color coupling in a pyrazolo[3,2-c]-1,2,4-triazole magenta coupler and L denotes a linking member which is not split off in the color coupling reaction and which cointains a ballast residue unless a ballast residue which cannot be split off is attached to the non-coupling ring of the bicyclic group Q.
