摘要:
An object of the present invention is to provide a polarizing laminate which is resistant to impact, has the high polarization degree, hardly causes a solvent crack, and hardly causes a fine crack even when perforation-processed, for example, goggles, sunglasses, prescription sunglasses, and shields which are resistant to impact, have higher stability, and can effectively prevent glare.There is provided a polarizing laminate comprising two protective sheets having approximately the same thickness, and a polarizer sheet held by them, wherein a protective sheet and a polarizer sheet are adhered, the protective sheet is any of a polyamide-based resin sheet, and a polyurethane-based resin sheet, and the laminate has the function as an optical lens.
