RADIATION CURABLE RESIN, LIQUID CRYSTAL SEALING MATERIAL, AND LIQUID CRYSTAL DISPLAY CELL USING SAME |
摘要 |
<p>[PROBLEMS] To provide a radiation curable resin having an extremely low possibility of contaminating liquid crystals, and a liquid crystal sealing material using such a photopolymerization initiator. [MEANS FOR SOLVING PROBLEMS] A liquid crystal sealing material characterized by comprising (a) a radiation curable resin represented by the general formula (1) below, (b) a photopolymerization initiator and (c) a filler having an average particle diameter of not more than 3 µ m.
(In the formula (1), R1 represents a hydrogen atom or a methyl group; R2 may be the same or different and represents a hydrogen atom, a halogen atom, a hydroxyl group, a monovalent linear, branched or cyclic alkyl group having 1-10 carbon atoms or an alkoxy group having 1-10 carbon atoms; m represents an integer of 1-4; R3 represents a hydrogen atom or a methyl group; R4 represents a linear, branched or cyclic alkyl group having 1-10 carbon atoms; 1 represents a range of positive numbers from 1 to 5; and the repeating unit number n represents a range of positive numbers from 0 to 20.)</p> |
