[[Also in Divisions C3 and D1] A setting lotion suitable for application to hair comprises a solution, e.g. alcoholic, a coloured polymer consisting solely of repeating units of formula (a) or solely of formula (a) and of formula (b) where R is H, CH 3 or C 2 H 5 , Q is a tetravalent hydrocarbon radical derived from a polymer of an ethylenically unsaturated anhydride, consisting of repeating units of formula where D is a mono-cyclic or poly cyclic amino dye nucleus, A is the residue of a monohydric alcohol of formula A.OH and p is 0 or 2-6. In the examples the polymers were made by condensing (1) poly(maleic anhydride) with n-butyl alcohol and a dye of formula (2) poly(itaconic anhydride) with n-ibutyl alcohol and a dye of formula (3) poly(acrylic anhydride) with n-butyl alcohol and a dye of formula (4) poly(methacrylic anhydride) with n-butyl alcohol and a dye of formula and (5) poly(acrylic/methacrylic anhydride), with n-butyl alcohol and the dye (IV). These polymers are compounded in the examples (A to C) with Z-amino-2-methyl-1-propanol, ethyl alcohol, water and a methyl vinyl ether/butyl monomaleate copolymer to form hair setting lotions.</p> |
