Zusammenfassung:	PURPOSE:To enable the bonding of coarse-surface plastics to each other or of a coarse-surface plastic to paper, by using a two-pack adhesive compositoin which comprises the first liquid consisting mainly of a copolymer resin emulsion and the second liquid consisting of an isocyanate. CONSTITUTION:A two-pack adhesive composition for a coarse surface comprising 100pts.wt. first liquid and 0.5-6pts.wt. second liquid which are mixed just before use. The first liquid is prepared by mixing 100pts.wt. (solid content) ethylene-vinyl acetate copolymer emulsion and/or acrylic ester-vinyl acetate copolymer emulsion with 1-30pts.wt. plasticizer (e.g., a phthalic ester) and 1-30pts.wt. water-soluble resin (e.g., a polyvinyl alcohol or hydroxyethyl cellulose). the second liquid comprises an isocyanate, preferably hexamethylene diisocyanate or tolylene diisocyanate.
