ABSTRACT:
There is described a waterproof support material for light-sensitive materials with an anti-curl layer applied in two successive coatings on the reverse side.
With the first coating, gelatin is dried out from the sol form and hardened in such a manner that, after the drying of the first coating, the second coating, which contains additional hardening agent, can be applied immediately without difficulty. Chromium(III)-salts are contained in both coatings as hardening agents.
Through the selected combination of 2 process steps, anti-curl layers of extremely low water absorption capacity are obtained.
