PRESSURE SENSITIVE ADHESIVE COMPOSITION

摘要

Provided are a pressure-sensitive adhesive composition, a pressure-sensitive adhesive optical laminate, a pressure-sensitive adhesive polarizing plate and a display device. The pressure-sensitive adhesive composition offers a pressure-sensitive adhesive that has excellent durability and processability in manufacturing due to increased hardness even when the pressure-sensitive adhesive layer is formed thinner than a typical adhesive composition, and that can prevent a pressure mark and leakage of the pressure-sensitive adhesive, as well as a bending problem generated when applied on an optical member such as a polarizing plate, etc.

主权项

1. A pressure-sensitive adhesive composition, comprising:
a pressure-sensitive adhesive polymer including a polymerization unit of a first monomer which forms a homopolymer having a glass transition temperature of less than 0° C., a polymerization unit of a second monomer which forms a homopolymer having a glass transition temperature of 0° C. or more, and a polymerization unit of a cross-linking monomer, and having an acid value of 1 mgKOH/g or less; and a cross-linking catalyst in an amount of 1 to 40 ppm.
