An aqueous resin composition for paints, inks, adhesives, sealants or primers, which has good adhesion to polyolefin substrates, good compatibility with various polar resins, and does not contain organic solvents. I will provide a. SOLUTION: 100 parts by mass of an acid-modified polyolefin and 5 to 60 parts by mass of a surfactant are dissolved in 15 to 1900 parts by mass of a polymerizable monomer, and water is added in the presence of a basic compound to carry out phase inversion emulsification. Thereafter, an aqueous resin composition obtained by polymerizing the polymerizable monomer; and 100 parts by mass of the acid-modified polyolefin and 5 to 60 parts by mass of the surfactant are dissolved in the first polymerizable monomer, and the base Water is added in the presence of the polymerizable compound to effect phase inversion emulsification, and then the first polymerizable monomer is polymerized to form a resin composition, and then the second polymerizable monomer is added to the resin composition. In addition, an aqueous resin composition obtained by polymerizing the second polymerizable monomer, the total amount of the first and second polymerizable monomers being 15 with respect to 100 parts by mass of the acid-modified polyolefin. An aqueous resin composition obtained by using 1900 parts by mass. [Selection figure] None |
