Abstract:
This invention provides a water-based primer composition characterized by comprising an aqueous dispersion formed by dispersing unsaturated carboxylic acid- or acid anhydride-modified polyolefin (a) having a melting point of 50-120° C. and a weight-average molecular weight within a range of 30,000-200,000, and unsaturated carboxylic acid- or acid anhydride-modified polyolefin (b) having a melting point of 30-100° C. and a weight-average molecular weight within a range of 30,000-200,000, in an aqueous medium, the melting point of the modified polyolefin (a) being higher than that of the modified polyolefin (b) by at least 10° C.
