<p>The present invention provides an aqueous resin composition for paints, inks, adhesives, sealants, and primers, the composition having good adhesion to polyolefin substrates and good compatibility with various polar resins, and containing no organic solvent. Specifically, the present invention provides an aqueous resin composition obtained by dissolving 100 parts by mass of acid-modified polyolefin and 5 to 60 parts by mass of surfactant in 15 to 1900 parts by mass of polymerizable monomer, adding water in the presence of basic compound to perform phase inversion emulsification, and then polymerizing the polymerizable monomer;
an aqueous resin composition obtained by dissolving 100 parts by mass of acid-modified polyolefin and 5 to 60 parts by mass of surfactant in a first polymerizable monomer, adding water in the presence of basic compound to perform phase inversion emulsification, polymerizing the first polymerizable monomer to form a resin composition, adding a second polymerizable monomer to the resin composition, and then polymerizing the second polymerizable monomer; the first and second monomers being used in a total amount of 15 to 1900 parts by mass per 100 parts by mass of the acid-modified polyolefin; and
paints, inks, adhesives, sealants and primers containing such composition as an active ingredient.</p> |
