(57) [Abstract] (with correction) [PROBLEMS] Acrylic adhesive for optical members that is excellent in stress relaxation and has little distortion even when used for an optical member with a large bonding area, and does not substantially contain water and solvent. The present invention provides an agent composition and a method for producing an acrylic pressure-sensitive adhesive sheet for an optical member using the composition. SOLUTION: 100 parts by weight of an acrylic monomer, 5 to 100 parts by weight of an acrylic high molecular weight polymer having a weight average molecular weight Mw of 100,000 or more, a weight average molecular weight Mw of 50,000 or less, and a glass transition point Tg of less than 20 ° C. 30 to 300 parts by weight of an acrylic low molecular weight polymer which is a photopolymerization initiator 0.01 Acrylic pressure-sensitive adhesive composition for an optical member containing about 5 parts by weight, a crosslinking agent, and substantially free of water and solvent, and the composition was cast on a support, and the amount of residual monomer was reduced. 5 Strength of 1 to 500 (W / m 2 ) Photopolymerization is carried out by irradiating the ultraviolet rays, and heating and drying are performed so that the residual monomer becomes 5000 ppm or less. |
