An adhesive constituent for optics, an image display device, and an input/output device
Document Type and Number:
Japanese Patent JP6131153
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical adhesive composition capable of obtaining an adhesive layer which reduces a relative dielectric constant and has excellent flexibility.SOLUTION: There is provided an optical adhesive composition which comprises (A) a hydrogenated block copolymer, (B) a first compatibilizing agent and (C) a second compatibilizing agent, wherein the (A) component has a hard segment constituted of a polymer component composed of an aromatic vinyl monomer and a soft segment constituted of a polymer component composed of a conjugated diene monomer, the (B) component has a property compatible with the hard segment and has a softening point of 50°C or less, the component (C) has a property compatible with the soft segment and a softening point of 50°C or more to 140°C and is contained in an amount of 2 to 50 pts.mass based on 100 pts.mass of the component (A) and an adhesive layer obtained from the optical adhesive composition has a relative dielectric constant of 1 to 3.5.
