RESIN DISPERSION, COATING MATERIALS, LAMINATES, AND PROCESSES FOR PRODUCTION OF THE SAME

摘要

To provide an aqueous dispersion of a resin wherein dispersed particles are stable with fine particle sizes and whereby bleeding out is suppressed, which is thus useful as e.g. a surface treating agent, an adhesive or a coating material for a polyolefin substrate. A resin dispersion having, dispersed in water with a 50% particle diameter of at most 0.5 µm, a polymer (C) having a hydrophilic polymer (B) or an acidic group bonded to a propylene/±-olefin copolymer (A) as a copolymer of propylene with an ±-olefin other than propylene, wherein the copolymer (A) has a propylene content of at least 50 mol% and less than 100 mol%, and the copolymer (A) has a weight average molecular weight Mw of at least 10,000 and a molecular weight distribution Mw/Mn of at most 3.5; and the resin dispersion has a surfactant content of at most 15 parts by weight per 100 parts by weight of the polymer (C); and a coating material or laminate, made by using such a dispersion.
