摘要 |
<p>The present invention relates to a pressure-sensitive adhesive composition used for a pressure-sensitive adhesive sheet to be directly attached to a metal surface, the composition including, a monomer mixture or an acrylic copolymer material obtained by at least partially polymerizing the monomer mixture, the monomer mixture including: at least one monomer (monomer ml) selected from alkyl (meth)acrylates represented by the following formula (I): CH 2 =C(R 1 )COOR 2 in which R 1 is a hydrogen atom or a methyl group, and R 2 is an alkyl group having 1 to 20 carbon atoms, and N-methylol (meth)acrylamide (monomer m2); in which the monomer ml and the monomer m2 are contained in a total amount of 60% by weight or more based on the total amount of the monomer mixture, and the monomer mixture includes substantially no carboxyl group-containing monomer.</p> |
