<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive for optical films which prevents a pressure-sensitive adhesive layer from foaming, causes no exfoliation from a polarizing plate or the like even under heating or humidification/heating conditions, and makes the pressure-sensitive adhesive layer ease the concentration of stress, which is caused by the expansion and contraction of the polarizing plate or the like, not to cause a light leakage phenomenon to a liquid crystal display device. <P>SOLUTION: The pressure-sensitive adhesive for optical films includes an acrylic copolymer (A) and an isocyanate compound (B). In this case, the acrylic copolymer (A) is obtained by copolymerizing 0.01-0.5 pts.wt. of a monomer (a-1) having hydroxy groups and other monomers (a-2). The pressure-sensitive adhesive for optical films has 0.5 (inclusive)-300 (inclusive) mol of the isocyanate groups of the isocyanate compound (B) to 1 mol of the hydroxy groups which the acrylic copolymer (A) has. <P>COPYRIGHT: (C)2012,JPO&INPIT |
