Title:
PRESSURE-SENSITIVE ADHESIVE TAPE AND ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/004056
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a pressure-sensitive adhesive tape which can maintain excellent adhesive strength over a long period of time even in cases where sweat, sebum, and the like, have adhered to the tape, and which exhibits excellent impact resistance and repulsion resistance.
The present invention relates to a foam pressure-sensitive adhesive tape which has a specific foam density, wherein a pressure-sensitive adhesive layer contains an acrylic pressure-sensitive adhesive containing an acrylic copolymer and a specific content of a crosslinking agent. The acrylic copolymer contains a specific content of (A) a carboxyl group-containing monomer, (B) a hydroxyl group-containing monomer and (C) another alkyl (meth)acrylate monomer as constituent components. The average number of carbon atoms in a saturated hydrocarbon group in the monomer (C) is less than 4.
