Abstract
A coating composition comprising (a) a hydrophilic copolymer of ethylene, alpha,beta-ethylenically unsaturated carboxylic acid and polyvalent alcohol monoester of alpha,beta-ethylenically unsaturated carboxylic acid, (b) a water-soluble base, (c) water, and if required, (d) one or more compounding agents, can form on substrates such as glass, plastics, metals and fibers films having excellent hydrophilic nature, water resistance, surface hardness, resistance to scuffing, adhesion to the substrates, and the like.
