Description

1225006 A7 ____B7_ V. Description of the Invention (彳) Technical Field The present invention relates to a plastic molded body which has anti-glare properties due to its light-color characteristics and / or polarized characteristics, and has excellent optical characteristics. In particular, it is a plastic lens molded body that has excellent appearance and optical characteristics and is easy to manufacture and process, and is used for anti-glare purposes such as sunglasses that are thrown away after use. BACKGROUND OF THE INVENTION As for the use of transparent plastic products with anti-glare properties, there can be listed: windows related to construction, sunshade roofs or windows, sunglasses or goggles related to automobiles, and lighting appliances or decorations to other aspects . In particular, in the United States in recent years, the demand for plastic lenses using transparent polycarbonate with excellent impact resistance has been growing rapidly for sunglasses and the like that are discarded after use. Accompanying this phenomenon, the development of lens materials for spectacles having superior optical characteristics compared to aromatic polycarbonates is progressing vigorously. For example, in Japanese Patent Application Laid-Open No. 1 2-6 3 5 06, a material having an excellent balance of optical properties using an aromatic-aliphatic copolymerized polycarbonate resin material as a lens material is disclosed. When this material is used in a lens substrate, when the object is viewed through the lens, the Abbe number (Abbé number: the number representing the degree of color difference of the lens material), which is the brightness of the image, is different from ordinary aromatic polycarbonate. The ester is 2 9 as high as 3 9, and a vivid image can be observed. In addition, in terms of refractive index, the China National Standard (CNS) A4 specification (210 ×: Z97 mm) is applicable to the general paper size used as a material for optical applications ~ -4- (Please read the precautions on the back before filling (This page)

Description of the invention (2) Polymethyl methacrylate is 1.49 and the material is 1.57. It has 1 · The high refractive index of 5 9 is approximately equal. When used in spectacle lenses that have been lost after use, the thickness can be reduced, which is more suitable for spectacle lenses that are required to be easily made. Polarized sunglasses have excellent anti-glare properties that block reflected light. Their usefulness in outdoor activities such as sea sports, skiing, and fishing has become widely recognized, and they need to show recent sharp elongation. . Especially when it is made of aromatic polycarbonate, it tends to be remarkable because of its superior impact resistance. On the other hand, with the development of superior light color pigments, rapid progress has been made in response to the surrounding brightness and the change in transmittance. The improvement of anti-glare plastic light color sunglasses is also significant, and it is still rapidly gaining popularity. welcome. However, the processing of plastic light-colored sunglasses is not easy. For example, the polycarbonate lens described in Japanese Patent Application Laid-Open No. 6 1-5 9 10 is used for the manufacture of polycarbonate plates. A lens containing a photochromic pigment only has a response speed, which is insufficient for this. Even if it is a resin other than polycarbonate, it also has a strength that can be used as an anti-glare material. When it is kneaded, it will cause the degradation of light color pigments. It is troublesome during kneading. Or problems such as slow response times are more common. In addition, in the case of a lens substrate using aromatic polycarbonate, as described above, because the Abbe number is small, the fresh brightness of the image is slightly inferior, and the internal strain and deformation of the high photoelasticity coefficient are large. Further improvements in optical characteristics are to be expected.

Description of the invention It can be manufactured by heating to a temperature slightly higher than the glass transition temperature (for example, about · 130 ~ about 180 ° C), and substantially stretching in one direction. In this case, the stretching ratio has an effect on the retardation 値. The e and g-type adhesive layers in FIG. 2 are used as adhesives for general bonding of a PC film and a polarizing film. However, any of them is preferable, but polyurethane resins are more suitable for use as an adhesive.

The thickness should be in the range of 5 2 to 1 0 0 // m, and more preferably 5 to 5 0 #m. When the thickness is less than 5 // m, it is difficult to obtain sufficient bonding strength. If it exceeds 100 #m, the bonding strength is sufficient, but it takes time to volatilize the solvent of the bonding layer, and the productivity or economical efficiency will be deteriorated. It is also possible to add a U V absorbent in this layer and provide U V blocking ability in the laminate. As mentioned above, when (C) is used in injection molding, it needs a thickness of more than 100 / m. If it is lower than this range, wrinkles or cracks are likely to occur during injection molding.
