| 摘要 |
The present invention provides a multi-layered PSA article having higher interlayer adhesive strength. The multi-layered PSA article of the present invention comprises a PSA layer (A) formed from a PSA composition (a) comprising an acrylic polymer (a) as a primary component, a PSA layer (B) formed from a PSA composition (b) comprising an acrylic polymer (b) as a primary component, and an intermediate layer (C) placed between the PSA layer (A) and the PSA layer (B), wherein the PSA composition (a) and the PSA composition (b) individually further comprise a compound having per molecule two or more functional groups that are capable of reacting with active hydrogen, and the intermediate layer (C) is formed from an intermediate layer composition (c) comprising a polymer (c) obtained by polymerizing a monomer composition (c) comprising a monomer having an active hydrogen. |
