The invention relates to an aqueous resin composition characterized by comprising 80 to 10 parts by weight of modified polyolefin with weight average molecular weight of 1000 to 100000, modified by copolymerizing polypropylene, polyethylene, copolymer of propylene or ethylene with α-olefin or degradation products of these under heat or with oxidizing agent, radical-generating agent or the like, with 0.1 to 20 % by weight of one kind or not less than two kinds of acid anhydride, carboxylic acid or alcohol with radically polymerizable double bond, and 20 to 90 parts by weight of one kind or a mixture of two or more kinds of acrylic or methacrylic monomers, mixed or dissolved and polymerized in water in the presence of surfactant and polymerization initiator. And, the aqueous resin composition of the invention not only shows excellent adhesion to polyolefin, but also has adherence to other organic substrates and inorganic substrates. In addition, because of little organic solvent contained, it is excellent in the aspects of safety and hygiene and environmental pollution. |
