[Also in Division B2] A composition comprises a pigment in admixture with at least 1% by wt. of an alkylated polymer of an N-vinyl heterocyclic monomer, e.g. a N-vinyl lactam or pyrrolidone, which has been prepared by (i) alkylating a polymer of a heterocyclic N-vinyl monomer with a C 2-2000α-olefine or poly-α-olefine or (ii) simultaneously polymerizing and alkylating a mixture of the N-vinyl monomer, the aboveα-olefine or poly-α-olefine and another monoethylenically unsaturated monomer, or another N-vinyl heterocyclic monomer. In examples numerous organic and inorganic pigments were used. In examples the above pigment compositions were used to colour lacquers consisting of nitrocellulose and glyptal resin, or a vinyl chloride/ acetate copolymer and a mixture of organic liquids; linseed oil and zinc oxide; or a mixture of soya bean oil/phthalic anhydride/ glycerine resin, xylol, TiO 2 , mineral spirit and cobalt naphthenate.</p> |
