Abstract

See full text

The present invention provides an aqueous dispersion comprising a polyamide-based rubber-like elastomer emulsified and dispersed therein, wherein 0.8 to 10 parts by weight of a copolymer of ethylene with an ethylenically unsaturated carboxylic acid, relative to 100 parts by weight of the polyamide-based rubber-like elastomer is contained. The aqueous dispersion of the present invention is a novel aqueous dispersion of polyamide-based rubber-like elastomer that is excellent in storage stability at low temperatures, and that can provide processed products excellent in flexibility and heat resistance when used as a coating material.
