AQUEOUS ADHESIVE COMPOSITION, METHOD FOR PRODUCING THE SAME AND ADHESIVE PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide an aqueous adhesive composition excellent in resistance to water whitening and adhesion even when used in a field particularly requiring resistance to water whitening and excellent in mechanical stability and application properties of adhesives even in a coating step for obtaining adhesive products, and to provide a method for producing the same and adhesive products. SOLUTION: The aqueous adhesive composition is composed of polymer particles [X] dispersed in an aqueous medium, wherein the polymer particles [X] comprise a vinyl polymer [A] containing a carboxy group and a cycloaliphatic hydrocarbon group and a polymer [B] containing a crosslinkable reactive group and a cycloaliphatic hydrocarbon group and have an acid value of 5-50 and an average particle size of 300 nm or less. The coating film formed from the aqueous adhesive composition has a glass transition temperature of -25°C or lower and a gel fraction of 25-80 wt%. The adhesive product is composed of a layer consisting of the coating film and a base material. The method for producing the aqueous adhesive composition is also disclosed.
