OPTICAL CLEAR ADHESIVE COMPOSITION AND ADHESIVE SHEET COMPRISING THE SAME

摘要

PURPOSE: An optical transparent adhesive composition and adhesive sheets are provided to prevent impact from external environment and improve durability under heat-resistant and moisture-resistant environment. CONSTITUTION: An optical transparent adhesive composition comprises polyol, acrylic monomer, isocyanate based crosslinker, and photopolymerization initiator. The polyol is more than 1type which is selected from the following polyols: polyether-based polyol, polyester based polyol, polycarbonate based polyol, and polycaprolactone based polyol. The acrylic monomers are 1-6 functional monomers. 7-230 parts by weight of the acrylic monomers are included in the acrylic monomer based on 100.0 parts by weight of polyol. The adhesive sheets include adhesive layers consisting of transparency adhesive composition in between 2 base films.
