    • In order for the discolored laminated glass lens for spectacles to have excellent glare-prevention characteristics, a tetraazaporphyrin compound is combined at a required concentration with an extremely thin adhesive agent layer in a manner so that unevenness of color does not arise, and of the light-absorbing ability expected for a laminated lens for spectacles. There is sufficient shielding of light in the vicinity of the 585 nm wavelength. In the laminated glass lens for spectacles, two glass lens substrates (2 and 3) (each about 1 mm thick) are bonded together with an adhesive agent layer (1) therebetween. A liquid substance of a solventless adhesive to which a pigment containing a tetraazaporphyrin compound is added together with an organic solvent is dropped onto the glass lens substrate (2) in the form of a droplet (1a; shown by phantom line in FIG. 1), and the other glass lens substrate (3) is pressed against the glass lens substrate (2) with a relatively light load to spread the droplet (1a) into a layer having a thickness of 5 to 150 micrometers, and allowing the thus spread layer to be cured as the adhesive layer (1).

    • The object is to provide a spectacle lens which contains an infrared absorbing agent, and which shows excellent infrared absorbing properties by minimizing deterioration and decomposition of the infrared absorbing agent, and to provide a method of producing such an optical lens.This infrared absorbing spectacle lens is formed by adding an infrared absorbing dye to a polyurethane resin obtained by addition polymerization of a prepolymer produced by reacting a polyisocyanate with a polyhydroxy compound, and an aromatic polyamine. show excellent infrared absorbing properties with no deterioration or decomposition of the infrared absorbing agent. It is possible to prevent deterioration of the infrared absorbing agent due to additives such as peroxides (including polymerization catalysts and initiators such as benzoyl peroxide), as well as increased absorption of visible light, which was difficult with conventional resin materials for molding. Also, because this lens can be molded at a relatively low temperature and it is not necessary to mold it at a temperature exceeding 250° C. as in the prior art, the infrared absorbing agent is less likely to deteriorate by heating.
    • 本发明的目的是提供一种含有红外线吸收剂的眼镜片,通过使红外线吸收剂的劣化和分解最小化,显示优异的红外线吸收特性,提供制造这种光学透镜的方法。 通过将聚异氰酸酯与多羟基化合物反应而得到的预聚物和芳香族多胺反应而得到的聚氨酯树脂中添加红外线吸收性染料,形成红外线吸收型眼镜镜片。 显示出优异的红外线吸收性能,不会使红外线吸收剂劣化或分解。 可以防止由于过氧化物(包括聚合催化剂和引发剂如过氧化苯甲酰)等添加剂引起的红外线吸收剂的劣化,以及可见光的吸收增加,这对于用于成型的常规树脂材料是困难的。 此外,由于该透镜可以在相对较低的温度下成型,并且在现有技术中不需要在超过250℃的温度下成型,所以红外线吸收剂不太可能因加热而劣化。

    • A light-shielding lens which can cut ultraviolet or visible radiation having wavelengths of 430 nm and shorter or of 500 nm and shorter and which can sufficiently satisfy users' demand for its color. The lens contains 0.01 to 2 parts by mass of an indole-based ultraviolet absorbing dye having a melting point of 140 to 150° C., based on 100 parts by mass of a synthetic resin forming the lens, and preferably further contains an oil-soluble dye, whereby the lens can cut ultraviolet and visible radiation having wavelengths of 430 nm and shorter. Since the predetermined amount of the indole-based ultraviolet absorbing dye is sufficiently dissolved in the synthetic resin, it efficiently reveals its expected function. The lens can thus cut ultraviolet and visible radiation having wavelengths of 430 nm and shorter, or even 500 nm and shorter, while keeping highly transparent light color.
