Abstract: Coloured polystyrene or styrene copolymers contain as dye up to 2% of dissolved anthraquinone - 2,1(N) - 11, 21(N) - benzacriolone, or anthraquinone - 2,1(N) - 11,21(N) - naphthacriolone, i.e. where rings I and II may be substituted by halogen atoms or alkyl groups. The styrene copolymers may contain butadiene, e.g. 10% acrylonitrile or acrylic esters. A number of the acriolone dyes are specified. The dyes are brought into a finely divided form before use. The compositions may be granulated before being molded or shaped into articles.
