| 摘要 |
The present invention is to sufficiently fixate chips even after cutting the chips in a chip cutting process and to improve the yield by preventing scattering of chips when cutting chips. The present invention provides a removable adhesive composition, which comprises an acrylic copolymer (A) and a cross-linking agent (B), wherein the monomer component constituting the acrylic copolymer (A) consists of (a) alkyl (meth)acrylate ester having an alkyl group with 4 or less carbon atoms, (b) a co-monomer, in which a glass transition temperature (Tg) of the homopolymer thereof is 80°C or higher, and (c) a monomer which has functional groups capable of reacting with the cross-linking agent (B), and the ratio of (a) alkyl (meth)acrylate ester monomer is 50 weight% or more to the total monomer components. |
