원문 (중국어)

There is provided a resin composition, containing (A) an acrylic resin, (B) an epoxy resin, and (C) a curing agent for the epoxy resin, wherein the acrylic resin (A) has a glass transition temperature of 5° C. to 35° C.; the acrylic resin (A) is a copolymer of starting material monomers containing (a1) methyl methacrylate, (a2) styrene and (a3) glycidyl (meth)acrylate; the proportion of the glycidyl (meth)acrylate (a3) in the total amount of the starting material monomers is less than 3.0% by mass; and the total content of the epoxy resin (B) and the curing agent for the epoxy resin, (C) is 1 part by mass to 30 parts by mass per 100 parts by mass of the acrylic resin (A). The resin composition can bring about good reworkability and good adhesiveness between sealing material layers.
