    Abstract: PROBLEM TO BE SOLVED: To provide an aqueous dispersion which develops the excellent adhesion (adhesiveness) to molded articles of various kinds of resins of polyolefins such as polypropylene, synthetic rubbers, unsaturated polyesters, epoxy resins, polyurethane resins or the like, or to metals such as steel plates and aluminum. SOLUTION: The aqueous dispersion comprises (A) a thermoplastic elastomer and (C) a urethane linkage-containing resin in the same particle; and the aqueous dispersion comprises a reaction product formed by reacting (A) the thermoplastic elastomer with (C) the urethane linkage-containing resin; and the aqueous dispersion comprises a reaction product formed by reacting (B) a functional group-modified thermoplastic elastomer with (C) the urethane linkage-containing resin; and in addition, the aqueous dispersion comprises such a copolymer of propylene-1-butene as (A) the above thermoplastic elastomer. The aqueous dispersion has a new, as never before, operational advantage that the aqueous dispersion can be used just as it is without causing a separation phenomenon in the aqueous dispersion and as a sprayable coating material, paint, a primer and an adhesive, and has the excellent adhesion to molded articles of various kinds of resins such as polyolefins and synthetic rubbers and to metals such as steel plate and aluminum. Also, this aqueous dispersion can use a curing agent reactive with an active hydrogen and/or a hydroxy group. Furthermore, the more excellent adhesive aqueous dispersion can be obtained by utilizing as (A) the thermoplastic elastomer, a propylene-1-butene random copolymer. COPYRIGHT: (C)2008,JPO&INPIT
