RELEASABLE ADHESIVE SHEET, METHOD FOR MANUFACTURING SAME, AND RELEASABLE ADHESIVE SHEET LAMINATE

WIPO Patent Application WO/2006/104235

A1

Disclosed is a releasable adhesive sheet comprising an adhesive layer which is formed by coating one surface of a base sheet with an adhesive containing a spherical adhesive agent and an emulsion binder adhesive agent. The spherical adhesive agent is composed of a spherical adhesive agent (A) which is obtained by polymerizing an ethylenically unsaturated monomer in the presence of 0.1-3 parts by mass of a polyacrylic acid per 100 parts by mass of the ethylenically unsaturated monomer component, or another spherical adhesive agent (B) which is obtained by adding 0.1-7 parts by mass of a polyacrylic acid per 100 parts by mass of the solid content of a spherical adhesive agent that is obtained by polymerizing an ethylenically unsaturated monomer. Such a releasable adhesive sheet does not vary very much in adhesiveness and releasability even when the pressures applied thereto are different, thereby exhibiting uniform adhesiveness and releasability.
