<p><P>PROBLEM TO BE SOLVED: To provide a self-adhesive composition giving a self-adhesive sheet whose self-adhesive performance is improved without using a carboxy group-containing monomer and to provide the self-adhesive sheet for sticking to a metal surface. <P>SOLUTION: The self-adhesive composition consists mainly of monomer components satisfying following (a) to (d) or an acrylic copolymer material formed by at least partially polymerizing the monomer components, wherein (a) 50 to 99.9 mass% monomer (m1) represented by CH<SB>2</SB>=C(R<SP>1</SP>)COOR<SP>2</SP>(R<SP>1</SP>denotes a hydrogen atom or a methyl group and R<SP>2</SP>denotes a 1-20C alkyl) is contained, (b) 0.1 to 25 mass% N-methylol (meth)acrylamide (m2) is contained, (c) the total content of m1 and m2 is≥60 mass% of the all monomer component, and (d) no monomer having a carboxy group is substantially contained. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
