    Abstract: 1,247,589. Treating keratinic fibres. L'OREAL. 9 June, 1969 [10 June, 1968], No. 29158/ 69. Heading D1B. [Also in Divisions A5, A6, C3, C4 and C5] Keratinic fibres, e.g. wool, are treated with polymers containing a -CO-NRM group where R is hydrogen, lower (C 1-6 ) alkyl or lower hydroxyalkyl and M is a group containing a thiol residue. The fibres may then be dyed. Exemplified polymers are the reaction product of #-mercaptoethylamine and N,N-diethylpropylene diamine with a maleic anhydride-itaconic anhydride copolymer and the reaction product of #-mercaptoethylamine with a methyl acrylate-acrylic anhydride copolymer.
