Title:
アクリル系粘着剤組成物、アクリル系粘着シートおよび該粘着シートの自動車塗膜面への接着方法
Document Type and Number:
Japanese Patent JP5581419
Kind Code:
B2
Abstract:
Disclosed is an acrylic pressure-sensitive adhesive composition that gives a pressure-sensitive adhesive layer exhibiting superior adhesiveness even to coatings, which are likely to cause low adhesion due to bleeding typically of a surface conditioner, without requiring, for example, washing process. The acrylic pressure-sensitive adhesive composition contains a vinyl monomer or a partial polymer thereof (a); and a (meth)acrylate co-oligomer (b), in which the vinyl monomer contains, as a main component, an alkyl (meth)acrylate monomer (a1) having an alkyl group with 2 to 14 carbon atoms, and the (meth)acrylate co-oligomer (b) has a weight-average molecular weight of from 1000 to 30000 and contains, as monomer components, 96 to 99.5 percent by weight of an alkyl (meth)acrylate (b1) and 0.1 to 4 percent by weight of a (meth)acryloyl group-containing silicone oil (b2).
