PURPOSE:To provide the titled adhesive capable of preventing fungus development and of shortening construction period, especially suitable for jointing between mortar construction and gypsum board, comprising hydroxyl group- contg. liquid diene polymer, polyisocyanate and polyol compound. CONSTITUTION:The objective adhesive comprising (A) a hydroxyl group-contg. liquid diene polymer (pref. a 4-12C diene (co)polymer with a number-average molecular weight 500-10,000 having terminal hydroxyl group of a content 0.3-5.0meq/g, e.g., butadiene homopolymer, butadieneacrylonitrile copolymer), (B) a polyisocyanate compound (pref. diphenylmethane diisocyanate) and (C) a polyol compound (pref. N,N-bis-2-hydroxyethyl aniline N,N-bis-2-hydroxypropyl aniline).
