UV-CURABLE BLU LIGHT GUIDE PLATE COMPOSITION AND A LIGHT GUIDE PLATE CAPABLE OF REPLACING AN EXISTING EXTRUDED LIGHT GUIDE PLATE OF A THERMOPLASTIC RESIN

摘要

PURPOSE: A UV-curable blu light guide plate composition and a light guide plate are provided to improve heat resistance, flexibility, mass producibility, and productivity.;CONSTITUTION: A UV-curable blu light guide plate composition comprises 20-75 weight% of polyurethane(meth)acrylate with MW of 1500-40,000, 15-70 weight% of ultraviolet ray reactive monomer, and 1-10 weight% of photopolymerization initiator based on total weight of the composition. The polyurethane(meth)acrylate with MW of 1500-40,000 is synthesized from polyol, diisocyanate, and mono(meth)acrylate with hydroxy group in which hydroxy group exists. A molar ratio of polyol: die isocyanate: hydroxy mono (meta) acrylate is 0.9 : 1.8 : 2 -3.3 : 4.3 : 2.;COPYRIGHT KIPO 2012
