A resin dispersion having, dispersed in water with a 50% particle diamter of at most 0.5 &#x3bc;m, a polymer (C) having a hydrophilic polymer (B) or an acidic group bonded to a propylene/&#x3b1;-olefin copolymer (A) as a copolymer of propylene with an &#x3b1;-olefin other than propylene, where the copolymer (A) has a propylene content of at least 50 mol% and less than 100 mol% and the copolymer (A) has a weight average molecular weight Mw of at least 10,000 and a molecular weight distribution Mw/Mn of at most 3.5, and the resin dispersion has a surfactant content of at most 15 parts by weight per 100 parts by weight of the polymer (C).

Resin dispersion, coating material, laminate, and processes for their production

To provide an aqueous dispersion of a resin wherein dispersed particles are stable with fine particle sizes and whereby bleeding out is suppressed, which is thus useful as e.g. a surface treating agent for a polyolefin substrate, an adhesive or a coating material. A resin dispersion having dispersed in water a polymer (C) having a hydrophilic polymer (B) bonded to a polyolefin (A) in a ratio of (A):(B)=100:5 to 100:500 (weight ratio); a method for producing the resin dispersion; and a coating material and a laminate, employing it.

Aqueous resin dispersion, method for its production, coating material and laminate

The present invention discloses an aqueous resin composition containing (A) a copolymer of (a) a monomer having one or more aldehyde groups or ketone groups, and a radical polymerizable unsaturated bond, in a molecule, with (b) a monomer having a radical polymerizable unsaturated bond copolymerizable with the monomer (a); (B) a hydrazine compound of the following formula (1)
