Title:
AQUEOUS PRIMER COMPOSITION AND METHOD FOR COATING PLASTIC MOLDED ARTICLE BY USING SUCH COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/094510
Kind Code:
A1
Abstract:
Disclosed is an aqueous primer composition containing an aqueous dispersion obtained by dispersing, in an aqueous medium, (a) an unsaturated carboxylic acid-modified or unsaturated carboxylic acid anhydride-modified polyolefin having a melting point of 50-120˚C and a weight average molecular weight of 30,000-200,000, and (b) an unsaturated carboxylic acid- modified or unsaturated carboxylic acid anhydride-modified polyolefin having a melting point of 30-100˚C and a weight average molecular weight of 30,000-200,000. This aqueous primer composition is characterized in that the melting point of the modified polyolefin (a) is higher than that of the modified polyolefin (b) by at least 10˚C.
