液晶硬化膜;LIQUID CRYSTAL CURED FILM

摘要

本发明之课题在于提供一种可容易地进行转印，且缺陷产生少、透明性优异之液晶硬化膜。解决手段为一种液晶硬化膜，其系由具有乙烯性不饱和键及芳香环的聚合性液晶化合物所形成，且满足式(Y)之液晶硬化膜。0.95>P1/P2>0.60(Y)[P1：相对于液晶硬化膜的厚度方向呈垂直的面中之一面的P值；P2：另一面的P值；P=I(1)/I(2)；I(1)：藉由红外线全反射吸收光谱测定所得的来自乙烯性不饱和键的面内弯曲振动的吸收峰强度；I(2)：藉由红外线全反射吸收光谱测定所得的来自芳香环的不饱和键的伸缩振动的吸收峰强度。] An objective of this invention is to provide a liquid crystal cured film allowing imprinting to be easily conducted, with less defect and excellent transparency. ;Provided is a liquid crystal cured film formed of a polymerizable liquid crystal compound having ethylenic unsaturated bond and aromatic ring, and satisfying the formula (Y). 0.95>P1/P2>0.60 (Y) [P1: the P value of one surface of the surfaces perpendicular to the thickness direction of the liquid crystal cured film, P2: the P value of the other surface, P=I (1)/I (2), I (1): the peak intensity from in-plane bending of ethylenic unsaturated bond detected by the IR total reflection absorption spectrum; I (2): the peak intensity from stretching of aromatic ring detected by the IR total reflection absorption spectrum]
