Title:
REMOVABLE WATER-DISPERSING ACRYLIC ADHESIVE COMPOSITION AND ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2011/132566
Kind Code:
A1
Abstract:
Provided is a water-dispersing acrylic adhesive composition that can form a removable adhesive layer that has excellent resistance to an increase in adhesive strength, appearance traits, and low contamination properties with respect to an adherend. The removable water-dispersing acrylic adhesive composition is composed of an alkyl (meth)acrylate ester and an unsaturated monomer containing a carboxyl group as an essential raw material monomer, and contains: an acrylic emulsion polymer (A), in which, of the total quantity of the raw material monomer, the content of alkyl (meth)acrylate ester is 70 to 99.5 wt%, and the content of the unsaturated monomer containing a carboxyl group is 0.5 to 10 wt%; a non-water-soluble crosslinking agent (B); an acetylenic diol (C); and a specific polyether-type defoaming agent (D). The HLB value of the acetylenic diol (C) is less than 13, the PO content of the polyether-type defoaming agent (D) is 70 to 100 wt%, and the number average molecular weight is 1200 to 4000.
