Aqueous dispersions and methods for their preparation, and compositions, adhesives and coatings

A water resistance particularly excellent in boiling water resistance and further excellent in shelf viscosity stability (long pot life) aqueous dispersion and a manufacturing method thereof, as well as compositions, to provide an adhesive and coating agent. (A) an at least one monomer unit selected from ethylenically unsaturated monomers and diene unsaturated monomers as a main component, and an unsaturated monomer having a carboxyl group, N - methylol (meth) acrylamide, N- butoxymethyl (meth) acrylamide, at least one of 0.1 to 10% by weight containing a crosslinkable unsaturated monomer units selected from diacetone acrylamide and acetoacetoxy ethyl (meth) acrylate polymer microparticles, (B) a vinyl alcohol polymer containing 10 mol% of ethylene units, wherein the vinyl alcohol polymer and (D) a crosslinking agent having (C) a carboxyl group, and the solids weight the ratio, (B) / (C) = 90 / 10~10 / 90, (A) / {(B) + (C)} = 99 / 1~80 / 20, {( A) + (B) + (C)} / (D) = 99.9 / 0.1~9 0/10 or above (A), (E) an ethylene unit 10 mol% and a carboxyl group-containing monomer units vinyl alcohol copolymer having a 0.1 to 10 mole% and (D) a crosslinking agent, includes, and, by solids weight ratio, (a) / (E) = 99 / 1~80 / 20, {(a) + (E)} / (D) = 99.9 / 0.1~90 / 10 in which the aqueous dispersion and a manufacturing method thereof, as well as compositions, to solve the above problems by adhesives and coatings. .BACKGROUND
