Problems solved by technology

[0006] For the above-mentioned polarizing glass lens sheet formed by covering both sides of the polarizing film layer with glass, since the base material of the cover layer is glass, it is easy to break, and the thermoforming of the base material is difficult, so the processability is not good enough.
[0007] In addition, for a polarizing plastic lens obtained by inserting a polarizing film layer into a mold and then casting, assembling the polarizing film layer into the mold requires high technology, and at the same time, due to the long-term Therefore, the polarizing film layer shrinks or thermally decomposes, thereby reducing its polarizing performance, which is a problem
[0008] In addition, Japanese Patent Laid-Open No. 8-52817 discloses an optical composite material obtained by thermally bonding a polycarbonate resin layer to a polycarbonate film on the outermost layer of a polarizing plate by insert injection molding. Molded products, for this kind of product, because the polarizer and the resin layer are too close, the heat generated during molding is directly transferred to the polarizer. Polarization performance degradation caused by decomposition

Embodiment 1

[0116] Using a TAC (triacetyl cellulose) film with a thickness of about 80 μm as a protective film layer, a polarizing plate (Sumitomo Chemical Co., Ltd. society).

[0117] A transparent nylon "Glylamide TR-90" (AIMS company) film with a thickness of about 200 μm is used as the resin film, and a layer of acrylic adhesive dyed gray with a thickness of about 30 μm is coated on one side of the film layer. The agent is "Saibinol (Saibinol AT-250" (Saiden Chemical Co., Ltd.).

[0118] The above-mentioned resin film was pasted on one side surface of the above-mentioned polarizing plate to form an intermediate composite.

[0119] The above-mentioned intermediate composite was press-molded into a spherical shape so that the TAC surface was on the convex side and the "Glylamide TR-90" surface was on the concave side with a curvature equal to that of the insert-molded concave mold.

[0120] The convex side of the obtained spherical intermediate complex is put into the concave mold, an...

[0127] Using a film made of polycarbonate (Idemitsu Petrochemical Co., Ltd.) with an average degree of polymerization of about 80 with a thickness of about 170 μm as the resin film layer, the adhesive used in Example 1 was coated with a thickness of about 30 μm. Binder.

[0128] The above-mentioned polycarbonate film was pasted on one surface of the polarizing plate used in Example 1 to prepare an intermediate composite.

[0129] In the same manner as in Example 1, the intermediate composite was pressure-molded into a spherical shape so that the TAC surface was on the convex side and the polycarbonate surface was on the concave side.

[0130] The press-molded intermediate composite was placed in the concave mold in the same manner as in Example 1, and a molding cavity was formed between it and the convex mold. Using a polycarbonate with an average degree of polymerization of about 80 as the thermoforming resin layer, the thermoforming resin layer is thermally bonded to the po...

Embodiment 3

[0135] A film made of polyethylene terephthalate (Idemitsu Petrochemical Co., Ltd.) with a thickness of about 200 μm was used as the resin film layer, and the adhesive used in Example 1 was coated thereon with a thickness of about 30 μm.

[0136] On one surface of the polarizing plate used in Example 1, the above-mentioned polyethylene terephthalate film was pasted to prepare an intermediate composite.

[0137] In the same manner as in Example 1, the intermediate composite was pressed into a spherical shape so that the TAC surface was on the convex side and the polyethylene terephthalate surface was on the concave side.

[0138] The press-molded intermediate composite was placed in the concave mold in the same manner as in Example 1, and a molding cavity was formed between it and the convex mold. A method in which polyethylene terephthalate is used as a thermoforming resin layer, and the thermoforming resin layer is thermally bonded to the polyethylene terephthalate surface of...

Abstract

A optical composite has high impact resistance and high degree of polarization, and is used as, for example, goggles, sunglasses, and spectacles, which have high impact resistance, has more safety, and can prevent dazzling light. The polarizing optical composite equipped with a polarizing plate holding a polarizer sheet layer between two protective sheet layers, wherein the polarizing sheet layer has on one side thereof at least two layers, in a body, constructed of materials different each other.

Description

Background technique [0001] The present invention relates to a lens base material and technology for providing a strong impact-resistant optical composite incorporating a polarizing film layer, for example, used in strong impact-resistant goggles, sunglasses, and prescription sunglasses. [0002] Goggles and glasses used in the field of sports equipment such as skis, snowboards, skates, speedboats, rowing boats, bicycles, motorcycles, etc., or in manufacturing, generally in industrial fields such as construction and civil engineering, are used to prevent direct sunlight The glare of light and reflected light and prevent wind, snow, rain, sea water, water, sand, medicine, foreign matter and other damage to the eyes. In addition, general-purpose sunglasses and prescription sunglasses are used to prevent glare from direct light and reflected light. [0003] Heretofore, a polarizing glass lens formed by covering both sides of a polarizing film layer with glass, or a polarizing pl...
