PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition suitable for releasing a molded product produced from an ultraviolet curable molding material. SOLUTION: It contains a (meth) acryl oligomer having a hydrogenated polybutadiene or hydrogenated polyisoprene skeleton and a photoinitiator that can be cured by ultraviolet irradiation, and after curing by ultraviolet irradiation, a glass transition temperature (Tg): − The pressure-sensitive adhesive composition was adjusted so as to exhibit an elastic modulus at 60 to -20 ° C and 25 ° C: 0.3 to 2.0 MPa and an SP value of 17.0 to 19.0 [MJ / m 3 ] 1/2. Constitute. [Selection] Figure 1 |
