PURPOSE:The titled adhesive providing a dried film of coating having adhesivity, having improved water resistance of film of coating, obtained by blending a mixed solution of an aqueous dispersion of a polymer comprising an ethylenic unsaturated carboxylic acid, etc., and a polyamide resin with a water-soluble or water-dispersible epoxy resin. CONSTITUTION:(A) An aqueous dispersion of a polymer having -60--10 deg.C Tg of polymer and 0.3-2.0 micron average particle diameter of dispersed particles obtained by radically polymerizing (i) 0.5-15pts.wt. ethylenic unsaturated carboxylic acid with (ii) 85-99.5pts.wt. copolymerizable ethylenic unsaturated monomer in water is blended with (B) 2-50pts.wt. (based on 100pts.wt. polymer of the component A) polyamide resin (e.g., condensate of aliphatic dicarboxylic acid and polyethylene polyamine) and then mixed with (C) a water-soluble or water-dispersible epoxy resin to give the aimed adhesive.
