  • Pressure-sensitive adhesive composition, process for producing same, and pressure-sensitive adhesive film
    Patent number: 10662355
    Abstract: The present invention is an adhesive composition that is characterized by including (A) a polymer comprising a structural unit having a hydroxy group in a side chain, (B) a compound having two or more isocyanate groups, (C) a bismuth carboxylate, and (D) a tertiary amine having a pKa of 6 or more. The polymer (A) may include further a structural unit having a urethane bond and a polymerizable unsaturated bond in a side chain.
    Type: Grant
    Filed: July 12, 2016
    Date of Patent: May 26, 2020
    Assignee: MITSUI CHEMICALS TOHCELLO, INC.
