Process for the production of a photographic black dye image which comprises (a) imagewise exposing photographic silver halide material comprising at least one silver halide emulsion layer coated on a support, there being present in the silver halide emulsion layer(s) or in a layer in operative contact with at least one silver halide emulsion layer a resorcinol compound of the formula ##STR1## where each of W, Y and Z is hydrogen, chlorine or bromine, a nitrogen-linked heterocycle, --SR.sub.1 where R.sub.1 is alkyl, aryl or a heterocycle or W, Y or Z is acylamino or --R.sub.3 where --R.sub.3 is alkyl, cycloalkyl or aralkyl or Z alone is --CO--R.sub.1 where R.sub.1 is as just defined but at least one of W, Y and Z must be --R.sub.3, and X which is the coupling position is hydrogen, chlorine or bromine, a nitrogen-linked heterocycle or --SR.sub.1, (b) color developing the exposed material using a color developing solution which comprises an aqueous alkaline solution of a primary aromatic amine color developing agent to form simultaneously a silver image and a black dye image, (c) optionally bleaching the silver image, and then (d) fixing out all the silver halide in the material using an aqueous solution of a silver halide solvent.

染料图像的过程包括:(a)对涂覆在支撑材料上的至少一层
银卤素乳剂进行成像曝光,其中
银卤素乳剂层或与至少一层
银卤素乳剂处于操作接触的层中存在式为##STR1##的邻二
酚类化合物,其中W、Y和Z中的每一个是氢、
氯或
溴、氮连接的杂环、--SR.sub.1,其中R.sub.1是烷基、芳基或杂环,或W、Y或Z是酰胺基或--R.sub.3,其中--R.sub.3是烷基、环烷基或芳基烷基,或仅Z是--CO--R.sub.1,其中R.sub.1如上所述,但至少有W、Y和Z中的一个必须是--R.sub.3,而耦合位置X是氢、
氯或
溴、氮连接的杂环或--SR.sub.1;(b)使用含有原芳香
胺类显影剂的
水性碱性显影液对曝光材料进行彩色显影,同时形成
银像和黑色
染料像;(c)可选地漂白
银像;然后(d)使用含有
银卤素溶剂的
水性溶液固定材料中的所有
银卤素。
