Problems solved by technology

[0020] In the case of using the photochromic plastics exemplified by the above-mentioned impregnation method for eyeglasses, since the base material is prepared separately and the photochromic compound is impregnated into the obtained base material, not only the production method is complicated, but also for To improve impregnation, it is necessary to lower the glass transition temperature (Tg) of the base material, so the flexibility of the base material becomes too high. As a result, the following new problems arise: the hardness of the base material decreases, the heat resistance decreases, There is a lot of optical distortion, etc.

Embodiment 1～9、 comparative example 1～6

[0347] The (A) radically polymerizable compound shown in Examples 1-9 of Table 1, and Comparative Examples 1-6, (C) photochromic compound, and other additive components were fully mixed at 70 degreeC. This liquid mixture was cooled to room temperature, (B) radical polymerization initiator was added, and it mixed at room temperature until it became uniform. Table 1 shows their compounding ratios.

[0348]The mixed solution containing the photochromic compound was poured into a mold formed by wrapping the outer peripheries of two disc-shaped glass plates with an adhesive tape, and casting polymerization was performed. During the polymerization, an air furnace was used, and the temperature was gradually raised to perform polymerization. After the polymerization, the casting mold was taken out from the air furnace, and after natural cooling, the solidified body was removed from the glass mold of the casting mold.

Abstract

The polymerizable composition of the present invention comprises: (A) a compound containing two or more allyloxycarbonyl groups represented by the following general formula (1), (B) a radical polymerization initiator selected from peroxyketal-based radical polymerization initiators, At least one polymerization initiator selected from the group consisting of peroxymonocarbonate-based radical polymerization initiators and perester-based radical polymerization initiators, and (C) at least one selected from the group of naphthopyran compounds Photochromic compounds.

Description

technical field [0001] The present invention relates to a polymerizable composition that can be suitably used for producing a cured photochromic body excellent in photochromic action. Background technique [0002] The so-called photochromic phenomenon refers to the reversible phenomenon that when a certain compound is irradiated with light containing ultraviolet rays such as sunlight or mercury lamp light, the color changes rapidly, and when the light irradiation is stopped and placed in a dark place, the original color is reversible. function, which has been used for various purposes. [0003] For example, the photochromic phenomenon has also been applied in the field of spectacle lenses. By curing polymerizable monomers to which various photochromic compounds having the above-mentioned properties are added, plastics having photochromic properties are obtained. lens. As the photochromic compound, a fulgimide compound, a spirooxazine compound, a chromene compound, etc. whi...
