Abstract (en)

[origin: EP0297240A2] For a waterproof support for light-sensitive materials with two successive coatings of an anti-curling layer applied to the back, gelatine is dried from the sol form in the first coating and hardened in such a way that, after drying of the first coating, the second coating which contains further hardener can immediately be applied without difficulty. Both coatings contain chromium(III) salts as hardener. <??>The chosen combination of two process steps provides anti-curling layers of extremely low water absorption capacity.
