Title:
PRESSURE-SENSITIVE ADHESIVE AND PRESSURE-SENSITIVE ADHESIVE FILM
Document Type and Number:
Japanese Patent JP2019077755
Kind Code:
A
Abstract:
To provide a pressure-sensitive adhesive from which a pressure-sensitive adhesive film having excellent removability and optical characteristics such as transparency and having good heat resistance, moisture heat resistance and water resistance can be produced, a pressure-sensitive adhesive film and an optical laminate.SOLUTION: The pressure-sensitive adhesive comprises a copolymer (A) having a hydroxyl group, a reactive compound (B) having a functional group reactive with a hydroxyl group, and a group 2 metal compound (C). The pressure-sensitive adhesive contains, as a monomer unit constituting the copolymer (A), a unit of an ethylenically unsaturated compound (a1) having a hydroxyl group, a unit of an ethylenically unsaturated compound (a2) having an alkyl group having 14 to 26 carbon atoms, and a unit of an ethylenically unsaturated compound (a3) having a functional group reactive with the above hydroxyl group, and contains, with respect to 100 pts.ms of the copolymer (A), 0.1 to 50 pts.ms of the reactive compound (B) having a functional group reactive with the hydroxyl group, and 0.001 to 20 pts.ms of the group 2 metal compound (C).SELECTED DRAWING: None
