A photochromic cured product which has excellent photochromism such as high color density and high fading speed, excellent adhesion to a hard coat and high striping work efficiency. This cured product is obtained by polymerizing and curing a curable composition which comprises (A) a polyfunctional polymerizable monomer such as trimethylolpropane trimethacrylate, (B) a silyl monomer such as γ-methacryloyloxypropyl trimethoxysilane, (C) another radically polymerizable monomer and (D) a photochromic compound. As for the contents of the polymerizable monomers, the content of the component (A) is 1 to 50 wt%, the content of the component (B) is 0.5 to 20 wt% and the balance consists of the component (C) based on the total of the components (A), (B) and (C). The photochromic compound (D) is contained in an amount of 0.0001 to 10 parts by weight based on 100 parts by weight of the total of the components (A), (B) and (C).
一种光致变色固化产品,具有优异的光致变色性能,如色彩密度高、褪色速度快、对硬涂层的附着力优异以及剥离工作效率高。这种固化产品是通过聚合固化一种可固化组合物获得的,该组合物包括:(A)一种多官能团可聚合单体,如三羟甲基丙烷三甲基丙烯酸酯;(B)一种硅基单体,如γ-甲基丙烯酰氧基丙基三甲氧基硅烷;(C)另一种可辐射聚合单体;(D)一种光致变色化合物。至于可聚合单体的含量,组分(A)的含量为 1 至 50 wt%,组分(B)的含量为 0.5 至 20 wt%,余量为组分(C),即组分(A)、(B)和(C)的总和。光致变色化合物 (D) 的含量为 0.0001 至 10 重量份(以 100 重量份的组分 (A)、(B) 和 (C) 的总和为基准)。
