The present invention provides a polymerizable composition having low birefringence which contains at least two types of polymerizable compounds represented by Formula (I):
in the formula, A represents a phenylene or a trans-1,4-cyclohexylene, L represents -OC(=O)-, -OC(=O)O-, and the like, m represents 3 to 12, Sp1 and Sp2 represent an alkylene of which -CH2- may be substituted with -O- or the like, and the like, and Q1 and Q2 represent a polymerizable group, and the like, in which when a number obtained by dividing the number of trans-1,4-cyclohexylenes represented by A by m is set to mc, the polymerizable compounds include a polymerizable compound satisfying 0.5 < mc < 0.7 and a polymerizable compound satisfying 0.1 < mc < 0.3. A film such as a low birefringence phase difference film or a reflection film having high selectivity in a reflection wavelength range can be provided by using the polymerizable composition.
本发明提供了一种具有低双折射的可聚合组合物,该组合物含有至少两种由式(I)表示的可聚合化合物:
式中,A 代表亚苯基或反式-1,4-环己烯,L 代表-OC(=O)-、-OC(=O)O-等,m 代表 3 至 12,Sp1 和 Sp2 代表其中-CH2-可被-O-等取代的亚烷基等、以及 Q1 和 Q2 代表可聚合基团等,其中,当将 A 所代表的反式-1,4-环己烯的数目除以 m 所得到的数字设为 mc 时,可聚合化合物包括满足 0.5 < mc < 0.7的可聚合化合物和满足0.1 < mc < 0.3的可聚合化合物。使用该可聚合组合物可以提供一种薄膜,例如低双折射相位差薄膜或在反射波长范围内具有高选择性的反射薄膜。
