ULTRAVIOLET RAY-CURABLE SILICONE ADHESIVE AGENT COMPOSITION, AND METHOD FOR PRODUCING LAMINATE

摘要

An ultraviolet ray-curable silicone adhesive agent composition comprising (A) a polysiloxane represented by formula (1): (R¹SiO_3/2)_a1(R¹₃SiO_1/2)_b1(X¹O_1/2)_c1 (wherein R¹ represents a monovalent hydrocarbon group wherein a methyl group accounts for 20 mol% or more and an alkenyl group accounts for 0.1 to 50 mol%; X¹ represents a hydrogen atom or the like; a1 represents 0.1 to 1; b1 represents 0 to 0.75; and c1 represents 0 to 0.1; and the requirement represented by the formula: a1+b1+c1 = 1 is satisfied), (B) a polysiloxane represented by formula (2): (R²₃SiO_1/2)_a2(R²₂SiO)_b2 (wherein R² represents a monovalent hydrocarbon group wherein a methyl group accounts for 20 mol% or more and an alkenyl group accounts for 0.01 to 25 mol%; a2 represents 0.001 to 0.67; b2 represents 0.33 to 0.999; and the requirement represented by the formula: a2+b2 = 1 is satisfied), (C) a hydrogen polysiloxane represented by formula (3): R³_dH_eSiO_[(4-d-e)/2] (wherein R³ represents a monovalent hydrocarbon group; and d and e represent numerical values satisfying the requirements represented by the formulae: 0.7 ≦ d ≦ 2.5, 0.01 ≦ e ≦ 1.0 and 0.8 ≦ d+e ≦ 2.7) and (D) a platinum-group catalyst capable of being activated with light having a wavelength of 200 to 500 nm. The ultraviolet ray-curable silicone adhesive agent composition can provide a cured article having excellent adhesion force to an object of interest even when being cured under room temperature.
