Abstract
An adhesive composition for use in bonding of a polarizing plate is prepared from acrylic-based polymer graft-polymerized and modified by a reactive silane coupling agent with a specific grafting position and an ordinary cross-linking agent. Compared with unmodified acrylic-based copolymers, the adhesive composition thus synthesized demonstrates high adhesion property, cohesion property, elasticity property and high durability and, when used in bonding of the polarizing plate, flexibly follows dimensional changes of the polarizing plate in a high-temperature high-humidity atmosphere, alleviates the phenomenon where the polarizing plate demonstrates uneven distribution of residual stress due to dimensional changes of the polarizing plate, and prevents light leakage and uneven color which might otherwise occur to the polarizing plate due to the aging, cracking, or peeling of a conventional adhesive.
