Pressure sensitive adhesive composition, product using the same, and display using the product

摘要

Disclosed is a pressure-sensitive adhesive composition which contains an acrylic polymer and a crosslinking agent. The acrylic polymer has a weight-average molecular weight of 40x104 to 160x104 and contains at least an alkoxyalkyl acrylate (Component A) and an acrylic monomer having a crosslinkable functional group (Component B). The monomer components constituting the acrylic polymer contain 45 to 99.5 parts by weight of Component A and 0.5 to 4.5 parts by weight of Component B to 100 parts by weight of total monomer components constituting the acrylic polymer, and the monomer components constituting the acrylic polymer contain substantially no carboxyl-containing monomers. This relates to improvements to provide pressure-sensitive adhesive compositions that show excellent coatability, transparency, adhesion (typically low-temperature adhesion), and resistance to blistering/separation and concurrently have anticorrosive properties.
