Problems solved by technology

Furthermore, in the case of using a polymerizable cholesteric liquid crystal material, due to the inhomogeneity of the alignment state, the alignment state changes from a planar (Planer) state to a focal conic (Focalconic) state, and due to the light scattering effect caused by the focal conic state, the The haze is greatly increased, and unevenness occurs due to partial generation of the focal conic state

Abstract

The present invention relates to a polymerizable composition which is useful as a material for liquid crystal devices, displays, optical components, coloring agents, security marking and laser light emission; and a thin film which is obtained from the polymerizable composition. The present invention provides a polymerizable liquid crystal composition which has excellent solubility in a solvent and good adhesion to a base and is capable of providing a thin film that has low haze and is free from unevenness. The present invention also provides a thin film which is obtained using the polymerizable liquid crystal composition and has excellent appearance. A composition and a thin film, which are free from unevenness and have low haze and good adhesion to a base, can be obtained at low cost by using a polymerizable liquid crystal composition of the present invention.

Description

technical field [0001] The present invention relates to a polymerizable composition useful as a liquid crystal device, a display, an optical component, a colorant, a security mark, and a member for laser light emission, and a film obtained from the polymerizable composition. Background technique [0002] In recent years, the development of polarizing plates, retardation plates, etc. using polymerizable liquid crystal materials has been actively carried out. These can be obtained by applying a solution containing a polymerizable liquid crystal material on a substrate subjected to rubbing treatment, drying the solvent, and then polymerizing with ultraviolet rays or heat. In addition, it is also known that if a polymerizable cholesteric liquid crystal material is prepared by adding a chiral compound to a polymerizable liquid crystal material, a circular vibration-light separation element can be obtained by the same method, and researches have been carried out on its use in brig...
