Abstract
(EN)
Provided is an aqueous dispersion-type adhesive composition that makes it possible to improve water resistance. This aqueous dispersion-type adhesive composition contains an acrylic polymer as a base polymer, an aqueous dispersion-type tackifying resin, and polyacrylic acid. The number average molecular weight of the polyacrylic acid is 2,000-500 × 104. The content of the polyacrylic acid is 0.3-7 parts by weight with respect to 100 parts by weight of the base polymer.

L'invention concerne une composition adhésive de type dispersion aqueuse qui permet d'améliorer la résistance à l'eau. Cette composition adhésive de type dispersion aqueuse contient un polymère acrylique en tant que polymère de base, une résine donnant du collant de type dispersion aqueuse et de l'acide polyacrylique. La masse moléculaire moyenne en nombre de l'acide polyacrylique est de 2 000 à 500 × 104. La teneur de l'acide polyacrylique est 0,3 à 7 parties en poids par rapport aux 100 parties en poids du polymère de base.
