More Information
Summary:The adhesive composition of the present invention has a gel fraction of 20-50%, which comprises an acrylic polymer obtained by polymerizing a monomer mixture comprising the following component (a) as a main component and the following component (b) in a proportion of 5-49 wt%: component (a): an alkyl (meth)acrylate wherein the alkyl group has 4 to 12 carbon atoms, component (b): a carboxyl group-containing monomer having a carboxyl group and an ethylenic unsaturated double bond, wherein component (b), when polymerized as a homopolymer has a glass transition temperature of not more than 70°C. The adhesive composition of the present invention is superior in all of the adhesion, impact resistance and repulsion resistance, and can adhere to a part having a coated film formed on a surface to be adhered.
