Claims
- 1. In a process for hardening gelatin for color photographic material which comprises; corona irradiating the surface of a substrate layer support comprised of a cellulose paper which is laminated with a layer of polyolefin on both sides to form an inner paper, said inner paper having an equilibrium moisture of 30-60% relative humidity, casting at least one gelatin-containing color component silver halide emulsion layer associated with a supported gelatin layer on said support, the improvement of adding to a casting solution for at least one layer for application, a solution consisting essentially of gelatin, a hardening solution of 0.4 to 0.8% by weight, based on gelatin, of 1,3,5-triacrylohexahydro-1,3,5-triazine and a polyhydric aliphatic alcohol with from 3 to 10 carbon atoms in an amount of 2 to 20 times the quantity of the hardener by weight on said support.
- 2. A process as claimed in claim 1, in which the polyhydric alcohol is glycerol or 1,1,1-trimethylol propane.
- 3. A process as claimed in claim 1 in which the layer of polyolefin is polypropylene, polyethylene or a mixture thereof.
