Title:
組成物、組成物層、光学積層体および画像表示装置
Document Type and Number:
Japanese Patent JP7355928
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing: a composition for the formation of an underlayer, said composition suppressing the occurrence of cissing during the formation of an underlayer, while enabling an optically anisotropic layer formed on the underlayer to have good liquid crystal alignment properties; a composition layer which is formed using this composition; and an optical multilayer body and an image display device, each of which comprises this composition layer. A composition according to the present invention contains a photo-alignable polymer and a surfactant; the photo-alignable polymer has a photo-alignable group, and a fluorine atom or a silicon atom; the surfactant has a fluorine atom or a silicon atom, while having a weight average molecular weight of 10,000 or less; and the liquid surface tension A1 of the surfactant and the liquid surface tension A2 of the photo-alignable polymer satisfy formula (IA). (IA): A2 – A1 ≥ 0.5 mN/m
