Abstract:
(EN) Disclosed is a silicon-based liquid crystal aligning agent which is used for film formation using an inkjet coating method.  Also disclosed is a liquid crystal alignment film having excellent in-plane uniformity and excellent straight advance properties in the film edge portion. Specifically disclosed is a liquid crystal aligning agent for inkjet coating, which is characterized by containing (A) a polysiloxane having an unsubstituted or fluorine atom-substituted side chain that is composed of a hydrocarbon group having 8-30 carbon atoms, (B) a glycol solvent having 2-7 carbon atoms, and a solvent (C) specified below. Solvent (C): one or more solvents selected from a group consisting of compounds represented by formula (T1), formula (T2) and formula (T3), ketones having 3-6 carbon atoms, and alkyl alcohols having 5-12 carbon atoms (In the formulae, X1, X3 and X5 each independently represents an alkyl group having 1-4 carbon atoms; X2 and X6 each independently represents a hydrogen atom or an alkyl group having 1-4 carbon atoms; X4 represents an alkyl group having 1-4 carbon atoms; P represents an alkyl group having 1-3 carbon atoms; m, n, j and k each independently represents an integer of 1-3; and h represents 2 or 3.)
(FR) L'invention concerne un agent d'alignement de cristaux liquides à base de silicium qui est utilisé pour former un film à l'aide d'un procédé de revêtement à jet d'encre. L'invention concerne aussi un film d'alignement de cristaux liquides qui présente une excellente uniformité en plan et d'excellentes propriétés d'avance rectiligne dans la partie de bord du film. L'invention concerne spécifiquement un agent d'alignement de cristaux liquides pour revêtement à jet d'encre, qui est caractérisé en ce qu'il contient (A) un polysiloxane comportant une chaîne latérale non substituée ou substituée par un atome de fluor et composée d'un groupe hydrocarboné doté de 8-30 atomes de carbone, (B) un solvant de glycol comportant 2-7 atomes de carbone et un solvant (C) spécifié ci-dessous. Solvant (C): un ou plusieurs solvants sélectionnés de le groupe constitué par les composés représentés par les formules (T1), (T2) et (T3), des cétones comportant 3-6 atomes de carbone, et des alcools alkyliques comportant 5-12 atomes de carbone. (Dans les formules, X1, X3 et X5 représentent chacun indépendamment un groupe alkyle comportant 1-4 atomes de carbone; X2 et X6 représentent chacun indépendamment un atome d'hydrogène ou un groupe alkyle comportant 1-4 atomes de carbone; X4 représente un groupe alkyle comportant 1-4 atomes de carbone; P représente un groupe alkyle comportant 1-3 atomes de carbone; m, n, j et k représentent chacun indépendamment un nombre entier compris entre 1 et 3; et h représente 2 ou 3).
(JA)  インクジェット塗布法を用いて成膜するケイ素系の液晶配向剤、膜の面内均一性、及び膜端部のエッジ直進性に優れた液晶配向膜を提供する。  フッ素原子が置換された又は未置換の、炭素数が8~30の炭化水素基からなる側鎖を有するポリシロキサン(A)、炭素数2~7のグリコール溶媒(B)及び下記の溶媒(C)を含有することを特徴とするインクジェット塗布用液晶配向剤。  溶媒(C):式(T1)、式(T2)及び式(T3)からなる群から選ばれる少なくとも1種の化合物、炭素数3~6のケトン、及び炭素数5~12のアルキルアルコールからなる群から選ばれる1種以上の溶媒。 〔式中、X、X及びXは、それぞれ独立に、炭素数1~4のアルキル基であり、X及びXは、それぞれ独立に、水素原子又は炭素数1~4のアルキル基であり、Xは炭素数1~4のアルキル基であり、Pは炭素数1~3のアルキル基であり、m、n、j、kは、それぞれ独立に1~3の整数である。hは、2又は3の整数である。〕
