In color photographic material with light-sensitive silver halide emulsion layer(s) and an associated development inhibitor-releasing (DIR) coupler, the DIR coupler (I) has a 1,2,3-triazolyl or a tetrazolyl-5-thio inhibitor group, linked to the coupler directly or by a timing group. In color photographic material with light-sensitive silver halide emulsion layer(s) and an associated development inhibitor-releasing (DIR) coupler, the DIR coupler is of formula A<11>-(TIME)n-INH (I) and has a 1,2,3-triazolyl or a tetrazolyl-5-thio inhibitor group, linked to the coupler directly or by a timing group: A<11> = residue of a coupler, which coupler with the oxidation product of a silver halide developer under photographic development conditions and hence releases a group of the formula; INH = 1,2,3-triazolyl (IIA) or a tetrazolyl-5-thio (IIB) group of the formulae; TIME = a linking group released with INH during development, which inhibits release of the INH group under development conditions; R<11>, R<12> = H, alkyl, aryl, alkaryl, S-R<13>, -COO-R<13>, -CON(R<13>)R<14>, -N(R<15>)R<16>, -OR<13> or heterocyclyl; at least one of R<11>, R<12> is not H; R<13>, R<14> = alkyl, aryl, alkenyl or alkynyl; R<15> = H or R<13>; R<16> = acyl or R<13>'; R<17> = H, alkyl, aryl or heterocyclyl; n = 0 or 1; R<11>R<12>, R<13>R<14> and R<15>, R<16> = 5-7-membered ring; at least one of R<11> or R<12> and R<17> = alk(en)oxy- or aroxy-alkoxy group of formula R<21>-(OCmH2m)r-O- (III); R<21> = alkyl, aryl or alkenyl; m = 2-4; r = 1-6
