Field of the Invention The present invention relates to an adhesive used for attaching a film or a metal foil to the surface of a molded article of a polymer material such as polycarbonate, urethane RIM, FRP, which tends to generate gas from the surface thereof over time. The present invention relates to an agent composition. More specifically, the present invention relates to a pressure-sensitive adhesive composition in which the film or the like does not bulge or peel due to gas (outgas) generated from the adherend to which the film is stuck.

ている。2. Description of the Related Art Urethane RIM and FR which have a short time after molding
It is known that P (polycarbonate) generates gas (outgas) from its surface. Therefore, the pressure-sensitive adhesive film attached to the surface has a drawback that gas is accumulated at the interface due to gas (outgas) generated from the adherend, causing blistering or peeling of the pressure-sensitive adhesive film. As a countermeasure, for example, Japanese Patent Application Laid-Open No. 61-141377 proposes a marking material comprising a continuous porous plastic film as a base material and an adhesive applied thereto.

る。Means for Solving the Problems The present invention has been intensively studied to achieve the above object, and as a result, the pressure-sensitive adhesive layer is made firm and tough and the adhesive strength is increased, so that the specific composition and the specific molecular weight can be reduced. The present invention was completed by finding that an adhesive obtained by reacting a specific amount of polyglycidylamine and zinc naphthenate with an acrylic copolymer having the same effectively prevents outgassing. That is, the present invention relates to an alkyl acrylate having 4 to 12 carbon atoms in an alkyl group having 0.1 to 10 parts by weight of an α, β unsaturated carboxylic acid.
