Abstract

Proteins, particularly gelatin, may be hardened by adding a compound or compounds having the general formula H2 = CH-A-Ar-SO2F wherein Ar represents an arylene or substituted arylene radical and A represents a bivalent radical containing a group which exerts an activating influence on the additive power of the ethylenic compound, particularly a carbonyl group. Compounds specified are m - fluorosulphonyl-N-acryloyl aniline, N-vinyl-N1-m-fluorosulphonyl-benzene-ureide, N-vinyl-N1-p-fluorosulphonyl-benzene-ureide and 2-acryloyloxy-fluorosulphonyl-chlorobenzene. m - Fluorosulphonyl-N-acryloylaniline may be prepared by reacting m-fluorosulphonyl aniline with acrylyl chloride. N-Vinyl-N1-p or m-fluorosulphonyl benzeneureide may be prepared by reacting p- or m-fluorosulphonylaniline with vinyl isocyanate. 2-Acryloyloxyfluorosulphonyl chlorobenzene may be prepared by reacting o-chlorophenol sulphonyl fluoride with acrylyl chloride. Specifications 822,061, 860,631, 860,632 and 891,221 are referred to.
