Transparent optical article

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...

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...
