Problems solved by technology

[0004] However, as a high-performance transparent optical article with polarizing function and dimming function, which can prevent glare caused by reflected light and can appropriately change the light-shielding performance according to the intensity of external light, so far, there is no practical product, and people are looking for it. It is desired to be able to provide such a highly functional transparent optical article at low cost

Embodiment 1

[0087] On one side of the polyvinyl alcohol series polarizing element layer with a layer thickness of about 20 μm, the corresponding solid content is coated with a film thickness of 30 μm, and the spirooxazine series light-adjusting pigments 1, 3, 3, and 5 are contained at 10% by weight. , 6-pentamethylspirocycle [Indolino (Indolino)-2,3'[3H]-naphthalene (2,1b) (1,4) the binder of oxazine (Saiting (Syden) chemical company "Sebinol (サイビノ-ル)" AT-245).

[0088] A polycarbonate layer sheet having a layer thickness of 400 μm prepared using polycarbonate having an average degree of polymerization of about 80 was attached to the adhesive surface.

[0089] Furthermore, in the same manner as above, the other side of the polarizing element layer was coated with an adhesive that did not contain a light-adjusting pigment, and the above-mentioned polycarbonate layer was attached to this portion. The resulting composite laminate was bonded at 40° C. to obtain a polarized light-adjustable t...

Embodiment 2

[0093] On one side of the polyvinyl alcohol series polarizing element layer with a layer thickness of about 20 μm, the corresponding solid content is coated with a film thickness of 30 μm, and the spirooxazine series light-adjusting pigments 1, 3, 3, and 5 are contained at 10% by weight. , 6-pentamethylspirocyclic [Indolino (Indolino)-2,3'[3H]-naphthalene (2,1b) (1,4) the binder of oxazine (Saiting (Siden) chemical company "Sebinol (サイビノ-ル)" AT-245).

[0094] A 400-μm-thick TAC-ply composite ply prepared by laminating two 190-μm-thick triacetate (TAC) plies was attached to the above-mentioned adhesive surface.

[0095] Furthermore, in the same manner as above, the other side of the polarizing element layer was coated with an adhesive that did not contain a light-adjusting pigment, and the above-mentioned TAC layer composite layer was attached to this portion. The resulting composite laminate was bonded at 40° C. to obtain a polarized light-adjustable transparent optical artic...

Embodiment 3

[0099] On one side of a polycarbonate layer sheet with a layer thickness of 400 μm prepared by mixing polycarbonate with an average degree of polymerization of about 80 with 1% by weight of the light-adjusting pigment used in Example 1, an adhesive was applied with a film thickness of 30 μm. A mixture (Saiden Chemical Co., Ltd. "Saibinol" AT-245) was used to prepare a polycarbonate laminate with a light-adjusting pigment compounded with a binder.

[0100] Furthermore, a polycarbonate laminate with an adhesive was prepared in the same manner as above except that no light-adjusting pigment was added.

[0101] On one side of the polyvinyl alcohol series polarizing element layer with a layer thickness of about 20 μm, the above-mentioned light-adjusting pigment compound polycarbonate layer with adhesive is attached, and the above-mentioned polycarbonate layer with adhesive is attached to the other side sheets and bonded. The obtained composite laminate was a polarized light-adjust...

Abstract

A polarizing / dimming transparent optical article having both a polarizing function and a dimming function, such as polarizing / dimming sunglasses, goggles, and lenses. The transparent optical article is a transparent optical article of a laminated structure containing one layer of polarizer sheet, wherein at least one layer other than the polarizer sheet has a dimming function. A plurality of sheets provided with one layer of polarizer sheet and at least one layer of other sheet are bonded together by an adhesive or a tackifier to constitute a composite sheet-like item, and at least one layer of the other sheet and the adhesive or the tackifier in the composite sheet-like item has a dimming function.

Description

technical field [0001] The present invention relates to an invention related to a transparent optical article that can be used in sunglasses, goggles, lenses, and the like. Background technique [0002] If the vibration component of the light in the plane including the incident light and the normal direction is P-polarized light, and the vibration component in the plane perpendicular to it is S-polarized light, then the light reflected on a glossy surface such as glass or water surface and Corresponding to the reflection angle, the S polarized light increases monotonously, on the contrary, the P component has a near-zero minimum point near 60°. Therefore, if you use a polarizing filter that filters out S-polarized light and passes only P-polarized light, you can greatly reduce the glare caused by reflected light. Sunglasses with polarizing elements, ski goggles, corrective lenses, etc. well known. [0003] In addition, it can be used to impart light adjustment to sunglass...
