PURPOSE:To provide a composition for the bonding of rubber in water, etc., having excellent adhesivity and flexibility, and obtained by adding specific amounts of a hardly water-soluble amine and amide to an epoxy resin containing >=50wt% of an epoxy resin prepared by the reaction of a specific long-chain dibasic acid with an epoxy resin. CONSTITUTION:The objective composition is composed of (A) 100pts.wt. of epoxy resin composition containing >=50wt% of an epoxy resin obtained by reacting a long-chain dibasic acid of formula (R is alkyl or alkenyl wherein the C number of the straight chain is 2-8) with an epoxy resin having two or more epoxy groups in the molecule and (B) 4-430pts.wt. of a hardly water-soluble amine and/or amide (e.g. m-phenylenediamine, a polyamide derived from the dimer of linoleic acid and ethylenediamine, etc.). USE:It exhibits especially excellent adhesivity to chloroprene rubber.
