Title:
ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2020/050018
Kind Code:
A1
Abstract:
As an adhesive tape that exhibits excellent adhesive properties between a polyester-based adhesive layer and a polyolefin-based resin foam substrate, a urethane-based resin foam substrate or an acrylic-based resin foam substrate, the present invention provides an adhesive tape having an adhesive layer comprising a polyester-based adhesive on at least one surface of a substrate [I]. The substrate [I] is at least one type selected from the group consisting of a polyolefin-based resin foam substrate, a urethane-based resin foam substrate or an acrylic-based resin foam substrate. The polyester-based adhesive is formed from a polyester-based adhesive composition [II] containing a polyester-based resin (A) which has a weight average molecular weight of 5000-300,000 and has structural units derived from a polycarboxylic acid and structural units derived from a polyol, with the content of aromatic structure-containing compounds in the polycarboxylic acid being 80 mol% or less.
