Coloured hair lacquers or hair setting compositions containing a coloured macromolecular substance, are formed by chemically combining a dye with the macromolecular substance or by copolymerizing the dye with a colourless monomer. The dye may be combined with the polymer through the reactive groups by means of a condensation reaction. Suitable polymers are the copolymers of acrylamide or methacrylamide with acrylic acid esters, methacrylic acid esters, vinyl esters, vinyl lactams and if desired small amounts of unsaturated carboxylic acids. Dyes suitable for this purpose are those of the azo or anthraquinone series containing N-methylol groups as reactive groups. Dyes which can be used for copolymerization are those of the azo or anthraquinone series containing in the molecule a polymerizable olefinically unsaturated group outside the chromophoric system. Suitable monomers for copolymerizing with these dyes are acrylamide, methacrylamide, a low molecular weight acrylic esters or methacrylic ester, vinylacetate, vinyl-propionate and/or a vinyl-lactam. Specification 877,402 is referred to.ALSO:Coloured hair or hair setting compositions containing a coloured macromolecular substance are formed by chemically combining a dye with the macromolecular substance or by copolymerizing the dye with a colourless monomer.
