A novel polymerizable high-refractive index compound which is useful as an optical material, and a holographic recording medium using the same, which has high diffraction efficiency, high light transmittance and small rate of shrinkage, are provided. A composition for forming a holographic recording layer containing a reactive compound represented by the following formula 1, a holograph recording material, and a holographic recording medium provided with a recording layer containing the same, are disclosed.
(In the formula (1),
A is an optionally substituted ring;
Ar is an optionally substituted (hetero)aryl group formed by condensation of two or more rings;
R is hydrogen or a methyl group;
n is an integer of from 1 to 7; and
when n is 2 or more, then plural Ars may be the same as or different from each other,
provided that when A is an aromatic heterocyclic ring, and Ar is an optionally substituted (hetero)aryl group formed by condensation of two or more rings, then in the structure in which A and Ar are connected with each other, those partial structures that are in the structure of each of A and Ar, and are connected directly with each other, do not contain a heteroatom.)
提供了一种新型可聚合高折射率化合物,可用作光学材料,并使用该化合物提供了一种具有高衍射效率、高透光率和小收缩率的全息记录介质。公开了一种含有下式1所表示的反应性化合物的全息记录层组成物、全息记录材料以及具有含有该化合物的记录层的全息记录介质。(在式(1)中,A是可选择取代的环;Ar是由两个或多个环缩合而成的可选择取代的(杂)芳基基团;R是氢或甲基;n是1到7的整数;当n为2或更多时,多个Ar可以相同或不同,但当A是芳香杂环环时,且Ar是由两个或多个环缩合而成的可选择取代的(杂)芳基基团时,在A和Ar连接在一起的结构中,直接连接在一起的那些部分结构不包含杂原子。)
