Abstract:
Provided are a resin layer capable of strongly adhering to a rough surface and to a plastic, the resin layer having high holding power and exhibiting good adhesion even at low temperature, a resin composition suitable for forming the resin layer, and a layered sheet including the resin layer. The resin composition provided by the present invention contains a (meth)acrylic polymer having a Tg of -40 DEG C or below, and 5-40 parts by weight of a tackifying resin with respect to 100 parts by weight of the (meth)acrylic polymer. The (meth)acrylic polymer is a polymer of monomer components including: 50-97 wt% of an alkyl (meth)acrylate (A1) having a C8-18 branched alkyl group at a terminal end of an ester group, a homopolymer of the alkyl (meth)acrylate (A1) having a Tg of -50 DEG C or below;and 3-50 wt% of a (meth)acrylate (A2) having an ether bond in the molecular skeleton thereof, a homopolymer of the (meth)acrylate (A2) having a Tg of -40 DEG C or below.
