<P>PROBLEM TO BE SOLVED: To obtain an adhesive composition for installing an adhesive layer on a discotic liquid crystal layer of an optically functional film having the discotic liquid layer for expanding visible angle, and forming the adhesive layer excellent in adhesiveness not only to an object to be adhered but to the discotic liquid crystal layer, and excellent in durability (heat resistance, water resistance and the like) required in application to liquid crystal displays, and provide an optically functional film having the adhesive layer with visible angle expansion function. <P>SOLUTION: The adhesive composition for discotic liquid crystal comprises an acrylic copolymer as a main ingredient, a silane coupling agent and a tolylene diisocyanate-based cross linking agent (X) and other cross linking agent (Y) as cross linking agents. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
