PRESSURE-SENSITIVE ADHESIVE COMPOSITION FOR OPTICAL MEMBER, PRESSURE-SENSITIVE ADHESIVE LAYER FOR OPTICAL MEMBER, PRESSURE-SENSITIVE ADHESION TYPE OPTICAL MEMBER, AND IMAGE DISPLAY DEVICE

摘要

A pressure-sensitive adhesive composition for an optical member which comprises a (meth)acrylic polymer, a solvent (A) based on a hydrocarbon having 6 to 9 carbon atoms and a high boiling point and high solubility solvent (B) having a boiling point higher than that of the above hydrocarbon solvent and exhibiting the solubility for the (meth)acrylic polymer higher than that of the above hydrocarbon solvent, wherein the content of the solvent (A) based on the hydrocarbon is 20 to 60 wt % relative to the total amount of the solvents, and the ratio of the content (wt %) of the solvent (A) based on the hydrocarbon to that (wt %) of the high boiling point and high solubility solvent (B) (high boiling point and high solubility solvent (B)/hydrocarbon- based solvent (A)) is 0.05 to 4. The above pressure-sensitive adhesive composition for an optical member exhibits good applicability due to a reduced viscosity thereof, allows the reduction of the amount of an organic solvent to be used, and further can form a pressure-sensitive adhesive layer being excellent in durability and having a highly uniform surface.
