PRESSURE-SENSITIVE ADHESIVE COMPOSITION FOR OPTICAL MEMBERS AND PRESSURE-SENSITIVE ADHESIVE TAPE FOR OPTICAL MEMBERS |
摘要 |
Provided is a pressure-sensitive adhesive composition for optical members which is protected from whitening under high -temperature and high-humidity conditions and which can ensure high reliability. Also provided is a pressure-sensitive adhesive tape for optical members, which is produced using the pressure-sensitive adhesive composition. The pressure -sensitive adhesive composition for optical members comprises an acrylic copolymer obtained by polymerizing a mixed monomer which contains 1 to 25wt% of 2-hydroxyethyl acrylate, 1 to 25wt% of N-vinylpyrrolidone, 0.5 to 30wt% of a monomer having a structure represented by general formula (1-1), or 0.1 to 30wt% of a monomer having a structure represented by general formula (1-2). In general formula (1-1), R1 is hydrogen or methyl; R2 is hydrogen or alkyl having less than 3 carbon atoms; and n is an integer of 8 to 45. In general formula (1-2), R3 is hydrogen or methyl; R4 is alkyl having 3 to 30 carbon atoms; and m is an integer of 8 to 45. |
