Abstract
Abstract A two-part adhesive which comprises (i) as the main ingredient an emulsion consisting essentially of (a) an aqueous emulsion of a polymer or copolymer obtained from an essential monomer of an adduct of a tertiary amino group-containing acrylic or methacrylic acid ester and an epihalohydrin, (b) a tackifier resin selected from the group consisting of a petroleum hydrocarbon resin, a phenolic resin, a terpene resin, a rosin resin, a coumarone resin, and a coumarone-indene resin, and (c) an epoxy compound containing two or more epoxy groups in the molecule; and (ii) a curing agent selected from a primary or secondary amino group-containing compound. The adhesive is particularly useful for preparing automobile interior decorations, such as inside trims (e.g. doors, pillars), instrument panels, formed ceiling, and console box.
