摘要： A photographic recording material which comprises at least one gelatin-containing silver halide emulsion layer and at least one protective layer containing a gelatin derivative, the protective layer being further away from the layer support than each silver halide emulsion layer and 30 to 90% of the amino groups of the gelatin in the gelatin derivative being reacted with a monofunctional acid derivative, and which is hardened with an instant hardener can be produced at high speed and, hence, at high drying temperatures without any reticulation grain occurring during processing.
