PRESSURE-SENSITIVE ADHESIVE COMPOSITION FOR AN OPTICAL FILM

摘要

PURPOSE: An adhesive composition for optical film is provided to remarkably improve production efficiency and productivity of an optical film because effective coating process is possible in state of a large amount of solid phase, and to accurately and uniformly control physical properties such as a thickness of an adhesive layer. CONSTITUTION: An adhesive composition for optical film comprises: 100.0 parts by weight of an acrylic polymer comprising a radically polymerizable group and a thermosetting function group, and has a weight average molecular weight is 1,000,000; and 0.01-1.0 parts by weight of a crosslinking agent capable of reacting with the thermosetting functional group. A coating solid content of the adhesive composition is 20 weight% or more. The absolute value of different between a peel strength after 4 days since attached to a glass substrate with an adhesive form and a peel strength after 15 days sine attached.
