Title:
RESIN DISPERSION, COATING MATERIALS, LAMINATES, AND PROCESSES FOR PRODUCTION OF THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/105344
Kind Code:
A1
Abstract:
The invention provides a stable aqueous resin dispersion which contains dispersed particles having small diameters and is suppressed in bleed out and which is useful as a surface treatment, adhesive or coating material for polyolefin substrates, or the like. A resin dispersion obtained by dispersing a polymer (C) produced by binding a hydrophilic polymer (B) or an acid group to a propylene/α-olefin copolymer (A) made from propylene and an α-olefin other than propylene in water with the 50% particle diameter controlled to be 0.5μm or below, wherein the copolymer (A) has a propylene content of 50% by mole or above but below 100% by mole, a weight-average molecular weight (Mw) of 10000 or above and a molecular weight distribution (Mw/Mn) of 3.5 or below and the surfactant content of the resin dispersion is 15 parts by weight or below per 100 parts by weight of the polymer (C); and coating materials and laminates, made by using the dispersion.
