ANTISTATIC AGENT FOR LIQUID CRYSTAL AND LIQUID CRYSTAL COMPOSITION CONTAINING THE AGENT

摘要

PURPOSE: To obtain an antistatic agent for liquid crystal, having a specific heterocyclic structure and a specific molecular weight, capable of keeping the clear point, causing little lowering of the specific resistance of a liquid crystal composition, exhibiting excellent antistatic effect and useful for a liquid crystal electrooptical element, etc. ;CONSTITUTION: This antistatic agent is composed of a compound having a molecular weight of ≤300 and having a 5 or 6-membered heterocyclic structure containing nitrogen atoms and carbon atoms wherein at least one of the nitrogen atoms constituting the ring structure is bonded with H {e.g. a compound of the formula [R¹ to R⁵ are each H or an alkyl; A¹ is a (halogen or methyl- substituted) trans-1,4-cyclohexylene or a (halogen or methyl-substituted) 1,4- phenylene; (n) is 0 or 1]}. The agent is included in a liquid crystal composition in an amount of 0.001-5wt.%.;COPYRIGHT: (C)1996,JPO
