| 摘要 |
<p>The present invention relates to a liquid crystal aligning agent containing a radiation sensitive polyorganosiloxane which is obtained by reacting at least one selected from the group consisting of a polyorganosiloxane having a recurring unit represented by the following formula (1), a hydrolysate thereof and a condensate of the hydrolysis with a cinnamic acid derivative having at least one group selected from the group consisting of a carboxyl group, a hydroxyl group, -SH, -NCO, -NHR (R is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms), -CH=CH 2 and -SO 2 Cl:
(in the formula (1), X 1 is a monovalent organic group having an epoxy group, and Y 1 is a hydroxyl group, an alkoxyl group having 1 to 10 carbon atoms, an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms).</p> |
