Pigment dispersions and lacquers containing copolymer of isobornyl methacrylate

摘要: Low molecular weight copolymers (1) acrylic acid esters or methacrylic of alcohols such as methanol with (2) bicyclic isobornyl alcohol and unsaturated acids acid, contrasted high monomers (see U.S. Pat. No. 3,485,775) to other polymers, are found be exceptional in compatibility practically all types polyesters alkyds many lacquer film-forming materials. The modifiers, particulary for alkyds, need not selected on the basis oil length solvent (aromatic aliphatic), modifiers being compatible long medium short alkyds. When small amounts amine-containing carboxylic acids, polar combinations thereof, incorporated polymer solutions, they become improved pigment dispersants. Such dispersions, unexpectedly, can let down synthetic resins used by air-drying baking coated articles. Lacquers metals, paints, printing inks examples uses blends.
