Abstract:
Provided is a photochromic polarizing plate exhibiting reduced tint. The photochromic polarizing plate contains a laminate including at least one film, a polarizer, and an optically transparent substrate, wherein the photochromic polarizing plate has a single-plate transmittance T1(λ)% and a crossed transmittance T2(λ)% at a wavelength of λ nm satisfying Formulae (1) to (4): Formula (1) 55%≧T1(430)≧38%; Formula (2) 60%≧T1(590)≧42.5%; Formula (3) 1.0≧T1(430)/T1(590)≧0.9; and Formula (4) T2(430)≧0.02%.
