Abstract

Proteins, particularly gelatin, may be hardened by adding a compound or compounds having the general formula HO-Ar-SO2F wherein Ar represents an arylene radical or a substituted arylene radical and the hydroxyl and sulphofluoride groups are in ortho-, meta- or para-positions. The additive may be p-fluorosulphonyl phenol or m-fluorosulphonyl-o-chlorphenol. Specifications 822,061, 860,631, 860,632 and 891,221 are referred to.
