The developer for color silver halide photo papers containing hydrophobic color-forming components can be used in the chemical-photographic industry. The developer provides a reduction in the development time of color photographic paper based on silver chloride-silver emulsions containing not more than 80% AgBr, without degrading their photographic performance. This is achieved due to the fact that it contains, along with the traditional 2-amino-5 [N-ethyl-N (beta-methylsulfonamidoethyl)] -aminotoluene sulfate, a second, more active, developing substance - ethyloxyethyl paraphenylene diamine sulfate, as alkaline components - sodium phosphate and sodium hydrogen phosphate , as antivalent - 5-nitrobenzimidazole nitrate in the following ratio of components, g / l: disodium salt of ethylenediamine-N, N, N ', N'-tetraacetic acid - 1 - 3, sodium sulfite - 1 - 3, sodium phosphate 22 - 30, sodium hydrogen phosphate- 1 - 3, 5-nitrobenzimidazole nitrate - 0.02 - 0.03, hydroxylamine sulfate - 2.5 - 3.5, benzyl alcohol - 10 - 20 ml, ethylene glycol - 10 - 20 ml, 2-amino-5 [N-ethyl-N (beta-methylsulfonamidoethyl )] -aminotoluene sulfate monohydrate -5.5-6.5, ethyloxyethylparaphenylenediamine sulfate 0.5-1.5, distilled water up to 1 liter, pH 11.3-11.4.
