摘要：

PROBLEM TO BE SOLVED: To provide an optical laminate which offers good processability, surface hardness, and visibility through a pair of polarized sunglasses.SOLUTION: An optical laminate 1 comprises a hardened layer A made of an ionizing radiation curable resin composition formed on one surface of a plastic film having a retardation value of 3000-30000 nm or a plastic film that causes 1/4 wavelength phase difference, and a hardened layer B made of the ionizing radiation curable resin composition formed on the other surface. The hardened layers A and B each have a thickness of not less than 30 μm, and the total thickness is 64-350 μm. The plastic film 11 preferably has a thickness of 4-200 μm.
