向があり、その解決が求められていた。[Prior art and its problems] Pressure-sensitive adhesives used for double-sided adhesive sheets, adhesive labels, etc. are of course required to have excellent adhesive properties such as adhesive strength, cohesive force, and tack. However, in addition to this, it is also required to have excellent processing suitability when commercializing the adhesive processed original fabric. In other words, when commercializing double-sided adhesive sheets, adhesive labels, etc., the adhesive material is cut into a specified width using a slitter, slicer, etc., but if the adhesive sticks out or the adhesive is not cut properly, the blade may be damaged. The adhesive is required to have properties that prevent such phenomena from occurring, that is, so-called processability. However, conventionally provided adhesive compositions tend to have poor processability when adhesion, tack, etc. are improved, and a solution to this problem has been sought.

せることにより製造される。The copolymer used in the present invention consists of a methacrylic acid alkyl ester in which the alkyl group in the alkyl ester moiety has 8 to 16 carbon atoms (hereinafter referred to as "methacrylic acid C8-16 ester"), a functional monomer, and an alkyl methacrylate. It is produced by copolymerizing another vinyl polymer (hereinafter referred to as "vinyl monomer") copolymerizable with the ester using a conventional method.

ことが難しい。If the number of carbon atoms in the alkyl group of the methacrylic acid alkyl ester is less than 8 or more than 16, the glass transition point will be too high for use as the main monomer, making it impractical as an adhesive. Furthermore, even if these monomers are copolymerized with acrylic esters or the like that have a low glass transition point in order to compensate for this drawback, it is difficult to maintain a balance between adhesive properties and processability.
