Title:
WATER-BASED ADHESIVE AGENT COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/176544
Kind Code:
A1
Abstract:
Provided is a technique relating to an adhesive agent having both high water resistance and high adhesion performance. A water-based adhesive agent composition comprising a copolymerized dispersion which is produced by the emulsion polymerization of (a) 0.1 to 10 parts by mass of an ethylene-type unsaturated carboxylic acid monomer, (b) 60 to 99 parts by mass of an acrylic acid ester monomer having a C4-12 alkyl group and (c) 0 to 39.9 parts by mass of an ethylene-type unsaturated monomer [wherein (a)+(b)+(c) = 100 parts by mass] in a reaction system containing 0.1 to 10 parts by mass of a water-insoluble adhesiveness-imparting agent having an average particle diameter of 0.05 to 1.00 μm, wherein particles contained in the copolymerized dispersion have an average particle diameter of 0.3 to 10 μm, the glass transition point of the copolymerized dispersion is -70 to -30°C, and the solid content in a solution prepared by dissolving the copolymerized dispersion in tetrahydrofuran is 70 mass% or less.
