Disclosed is a multi-functional monomer including a heat-curable functional group as well as a typical photoreactive group. In the multi-functional monomer, the photoreactive group is not chained to a main chain of a polymer. Thus, since it is possible to perform desirable alignment treatment even though polarized UV is radiated for a short time, the production time and the production cost are reduced and alignment regulating force of liquid crystals is increased, thereby increasing a dichroic ratio.

[EN] Disclosed is a multi-functional monomer including a heat-curable functional group as well as a typical photoreactive group. In the multi-functional monomer, the photoreactive group is not chained to a main chain of a polymer. Thus, since it is possible to perform desirable alignment treatment even though polarized UV is radiated for a short time, the production time and the production cost are reduced and alignment regulating force of liquid crystals is increased, thereby increasing a dichroic ratio. [FR] L'invention concerne un monomère plurifonctionnel comprenant un groupe fonctionnel thermodurcissable ainsi qu'un groupe photoréactif type. Dans le monomère plurifonctionnel, le groupe photoréactif n'est pas relié à une chaîne principale d'un polymère. Ainsi, comme un traitement d'alignement souhaitable peut être exécuté en dépit du rayonnement d'UV pendant un bref laps de temps, il est possible de réduire à la fois la durée et le coût de fabrication tout en augmentant la force de régulation des cristaux liquides, ce qui accroît le rapport dichroïque.
