    摘要: An aqueous dispersed resin composition is disclosed, comprising (A) an aqueous dispersion of carbonyl-containing resin particles having an inner layer and an outermost layer, which is obtained by emulsion polymerization of a monomer mixture comprising (a) not less than 0.5% by weight of a carbonyl-containing monomer containing at least one aldo group or keto group and one polymerizable unsaturated double bond in the molecule thereof, (b) not less than 0.5% by weight of an ethylenically unsaturated carboxylic acid, (c) not more than 99% by weight of a monomer having a water-solubility of not more than 8 g/100 ml at 20.degree. C., and (d) not more than 99% by weight of an unsaturated monomer other than the monomers (a) to (c) in an aqueous medium in the presence of dispersed resin particles serving as an inner layer, (B) a hydrophilic compound comprising a hydrazine derivative containing at least two hydrazino groups in the molecule thereof, and (C) an epoxy-containing compound containing at least two epoxy groups in the molecule thereof, in which the resin constituting said outermost layer of said carbonyl-containing resin particles has a degree of solubilization of at least 5% by weight, and the resin constituting the whole resin particles has a degree of solubilization of from 4 to 50% by weight. The composition is easily crosslinked at room temperature to provide a film excellent in water resistance, resistance to whitening on contact with water, antiblocking properties, heat resistance, solvent resistance, adhesion and hardness, and is particularly useful as an adhesive composition.
