    摘要: To obtain elasticity imparting agents for paints comprised of liquid non-aqueous polymer dispersions which, when added to paints, improve the scratch resistance without lowering the acid resistance of the hardened paint film. A liquid non-aqueous polymer dispersion which contains (a) 40-90 percent by weight organic solvent, (b) 10-50 percent by weight particle component comprised vinyl based copolymer which contains 30 percent by weight or more of structural units of formula (1), and (c) 5-40 percent by weight dispersion stabilizer for dispersing the (b) component in the (a) component. In formula (1) R.sup.1 -R.sup.5 are H or methyl groups, m is 0-2, n is 0-10, p is 0 or 1, q is 0-3 and r is 0-3.
