摘要：
Azo dyes of formula II are released on development from dye releasers which are associated with a light-sensitive silver halide emulsion layer. The azo dyes are chelatable and form with metal ions blue or cyan dye-metal-complex image dyes. ##STR1## In the formula A.sup.1 and A.sup.2 represent electronegative substituents whose meta-sigma values .sigma..sub.m (according to D. H. McDaniel and H. C. Brown in J. Org. Chem. 23, 420 et seq (1958) conform to at least one of the following three relationships:1. .sigma..sub.m (A.sup.1), .sigma..sub.m (A.sup.2) +0.332. .sigma..sub.m (A.sup.1) +.sigma..sub.m (A.sup.2) +0.75;3. .sigma..sub.m (A.sup.1) +0.33 and A.sup.2 represents--SO.sub.2.sup.XX represents H, --OH, --NH.sub.2, --NH--Y or a cyclic amino group, andY represents alkyl, aryl, alkylsulfonyl, arylsulfonyl or acylQ represents a group for completing a 2-amino-3-hydroxypyridine ring, a 4,5-diphenylimidazole ring or a 4-hydroxyisoquinoline ring which is attached through the 1-position; andG represents a group capable of chelate formation.
