A photochromic curable composition that contains a (meth)acrylate compound represented by the following formula (1-X1);
(wherein Y is an oxygen atom or a divalent group represented by -NH-, R1 and R2 are hydrogen atoms or methyl groups, R3 is an alkylene group having 1 to 6 carbon atoms, R4 is an alkylene group having 1 to 6 carbon atoms, a cycloalkylene group having 3 to 8 carbon atoms and which may include a double bond, or an arylene group having 6 to 10 carbon atoms, and a is a positive number of 1 to 20), other radically polymerizable monomers and a photochromic compound. The invention provides a lens that features excellent durability and high photochromic property free of the problems of turbidity in the surfaces of the lens caused by bleed out or the peeling in the step of production.
一种光致变色固化组合物,它含有由下式(1-X1)表示的(甲基)丙烯酸酯化合物;
(其中 Y 是氧原子或由 -NH- 代表的二价基团,R1 和 R2 是氢原子或甲基,R3 是具有 1 至 6 个碳原子的亚烷基,R4 是具有 1 至 6 个碳原子的亚烷基、具有 3 至 8 个碳原子且可包括双键的环亚烷基或具有 6 至 10 个碳原子的芳烷基,a 是 1 至 20 的正数)、其他可辐射聚合的单体和光致变色化合物。本发明提供的镜片具有出色的耐久性和高光致变色性能,不会出现因生产步骤中的渗出或剥离而导致镜片表面浑浊的问题。
