ACRYLIC PRESSURE-SENSITIVE OPTICAL ADHESIVE COMPOSITION HAVING EXCELLENT REPEELING PROPERTIES AND LAMINATE USING SAME

摘要

PURPOSE: An acrylic pressure-sensitive optical adhesive compound having excellent repeeling properties because of its low adhesion in the initial attachment and generating no bubble or peeling phenomenon because of its adhesion increase with the laps of time and by heat and optical laminate using the same are provided which improve confidence because it is easy to remove an optical laminate when used to the optical laminate. CONSTITUTION: In an acrylic pressure-sensitive optical adhesive composition, the composition comprises 100 parts by weight of an acrylic pressure adhesive, 0.01 to 0.5 parts by weight of a cross linking agent and 0.01 to 10 parts by weight of polyalkylene oxide-modified polydimethylsiloxane copolymer of formula; Me3SiO(Me2SiO)x(MeSiPEO)ySiMe3. In formula, Me is methyl; PE is -CH2CH2CH2O(EO)m(PO)nZ; m and n is an integer, a sum thereof is more than 1, but n is not 0; EO is ethylene oxide; PO is propylene oxide; Z is H, amine or alkyl.
