  • Patent number: 4310453
    Abstract: Low molecular weight addition copolymers, of (1) (meth)acrylic acid esters of alcohols such as methanol and butanol with (2) esters of alcohols such as N-(.beta.-hydroxyethyl)oxazolidine and unsaturated acids such as a (meth)acrylic acid, and (3) optional .alpha.,.beta.-ethylenically unsaturated monomers such as a (meth)acrylic acid, are found to be exceptional dispersants for inorganic and organic pigments and colorants which are insoluble in organic solvents, for lacquers, and are compatible with practically all types of lacquer resins such as vinyls, nitrocellulose, and alkyds, and with many other types of lacquer film-forming materials. Usually, when small amounts of unsaturated carboxylic acids, or other polar monomers and combinations thereof, are incorporated in the polymers, they become improved pigment dispersants. Such pigment dispersions, unexpectedly, can be let down with many types of synthetic resins and used by air-drying or baking the coated articles.
