Embodiment 1
[0160] The following components were mixed to prepare a radically polymerizable component (A).
[0166] Other radically polymerizable monomers (A4)
[0167] GMA: 1 part by weight
[0168] αMS: 8 parts by weight
[0169] MSD: 1 part by weight
[0170] Fully mix 0.2 parts by weight of PC1 (photochromic compound (B)) and 1 part by weight of PerButyl ND (Perbutyl ND, polymerization initiator) in 100 parts by weight of the radically polymerizable component (A) prepared above to obtain photochromic curable composition.
[0171] The curable composition was poured into a mold sandwiched between a glass plate and a thiourethane-based resin plastic lens substrate with a refractive index of 1.60 using a spacer made of ethylene-vinyl acetatecopolymer, and casting was performed. plasti...

[0186] A photochromic curable composition was prepared in the same manner as in Example 1 except that the radically polymerizable component and photochromic compound described in Table 2 were used, and a photochromic laminate was produced in the same manner as in Example 1. body to evaluate. Table 3 shows the evaluation results.

Abstract
Provided is a photochromic curable composition containing the following: a silsesquioxanemonomer (A1) that has a radically polymerizable group and an acid value of 0.5 to 2.0 mgKOH / g; and a photochromic compound (B). This photochromic curable composition is suitable for use in the manufacture of a photochromic cured body that exhibits a superb photochromic effect, and is particularly suited to providing a photochromic cured body for obtaining, via a bonding process, a laminate that exhibits good adhesion.
Description
technical field [0001] The present invention relates to a novel photochromic curable composition suitably used for production of a photochromic cured product excellent in photochromic action, and a cured product obtained by curing the photochromic curable composition. Background technique [0002] Photochromism refers to a reversible action in which a certain compound changes color rapidly when it is irradiated with ultraviolet light such as sunlight or light from a mercury lamp, and returns to its original color when the light is stopped and left in a dark place. It has been used in various applications. . As photochromic compounds having such properties, fulugimid compounds, spirooxazine compounds, chromene compounds, and the like have been found. By compounding these compounds with plastics, optical articles having photochromic properties can be produced, and therefore, many researches on compounding have been carried out. [0003] For example, photochromism is also app...
