Abstract:
1. A thermocrosslinkable resin dispersion which comprises a continuous phase comprising an aqueous medium and a dispersed phase distributed therein; said dispersed phase comprising particles (I) of a resin component and particles (II) of a crosslinking agent as separately dispersed from the particles (I), said resin component comprising, as an essential constituent thereof, a polyolefin resin (a) or a mixture thereof with a vinyl resin (b), said resin (a) having a number average molecular weight of at least 1,500 and being comprised of a polyolefin polymer (a0) having been modified by the addition of at least one functional group species selected from the group consisting of carboxyl, hydroxyl, mercapto, amino, isocyanato and carbodiimido groups, said resin (b) having a number average molecular weight of 700 to 40,000 and a glass transition temperature of −65 to 40° C., and said crosslinking agent having at least two groups reactive with said resin (a); wherein the crosslinking agent has at least two reactive groups selected from the group consisting of hydroxyl, amino, epoxy and carbodiimido groups.
