ABSTRACT:
An aqueous resin dispersion useful as a primer capable of providing plastics products, in particular polyolefin plastics products, with good coatability characteristics. A thermocrosslinkable resin dispersion having a continuous phase having an aqueous medium and a dispersed phase distributed therein, the dispersed phase having particles (I) of a resin component and particles (II) of a crosslinking agent as separately dispersed from the particles (I), the resin component having, as an essential constituent thereof, a modified polyolefin resin (a) or a mixture thereof with a vinyl resin (b), the resin (a) having a number average molecular weight of at least 1,500 and having at least one functional group species selected from the group of carboxyl, hydroxyl, mercapto, amino, isocyanate and carbodiimide groups, the resin (b) having a number average molecular weight of 700 to 40,000 and a glass transition temperature of −65 to 40° C., and the crosslinking agent having at least two groups reactive with the resin (a).
