A photochromic hydroxyurethane compound of the present invention is characterized in that, on condition of having at least one photochromic moiety as the photochromic minimal unit in a molecule, it has a hydroxyurethane constitutional unit represented by Formula (1):
-X-O-CO-NH- (1).
In the formula, X is an oxygen-containing chain organic group having a hydroxyl group as a substituent, or a hydrogen atom in the hydroxyl group is substituted by any one of (A): a photochromic group having the photochromic moiety; (B): a polymerization reactive group having a polymerizable substituent; (C) an alkyl group having 1 to 10 carbon atoms; (D) a cycloalkyl group having 3 to 10 carbon atoms; or (E) : an aryl group having 6 to 14 carbon atoms (each of the groups (C)-(E) can be bonded to an oxygen atom derived from the hydroxyl group via the oxygen-containing chain organic group) .
本发明的一种光致变色羟基聚氨酯化合物的特征在于,在分子中至少有一个光致变色分子作为光致变色最小单元的条件下,它具有由式(1)表示的羟基聚氨酯构型单元:
-x-o-co-nh- (1).
式中,X 是以羟基为取代基的含氧链有机基团,或羟基中的氢原子被以下任一项取代 (A):具有光致变色分子的光致变色基团;(B).具有光致变色分子的聚合反应基团;(C).具有光致变色分子的聚合反应基团;(D).具有光致变色分子的聚合反应基团:(C) 具有 1 至 10 个碳原子的烷基; (D) 具有 3 至 10 个碳原子的环烷基;或 (E) 具有 6 至 14 个碳原子的芳基((C)-(E)中的每个基团均可通过含氧链有机基团与羟基衍生的氧原子键合)。
