| 发明名称 | Laminated glass lens for spectacles | ||
| 摘要 | In a laminated glass lens for spectacles, first and second glass lens substrates (each about 1 mm thick) are bonded together with an adhesive agent layer 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 first glass lens substrate in the form of a droplet, and the second glass lens substrate is pressed against the first glass lens substrate with a relatively light load to spread the droplet into a layer having a thickness of 5 to 150 micrometers, and allowing the thus spread layer to be cured as the adhesive layer. | ||

| 主权项 | 1. A laminated glass lens for spectacles, comprising two glass lens substrates laminated one on another through an adhesive layer,wherein the adhesive layer has a thickness of 5 to 150 μm and comprises a solventless adhesive, a pigment containing a tetraazaporphyrin compound and 0.2 to 2% by weight of an organic solvent, such that the laminated glass lens has a main absorption peak of visible light spectral transmission at wavelengths of 565 to 605 nm. | ||
