1. A photofunctional laminated article which comprises:
(L0) a transparent substrate,
(L1) a photofunctional layer comprising a fluorine-containing polymer (A) and a rare earth metal compound (B) and being formed
on the substrate (L0) and
(L2) a low refractive index layer formed on the layer (L1), and is characterized in that when refractive indices of each layer
are assumed to be n(L0), n(L1) and n(L2), the following equation:
n(L0)≧n(L1)>n(L2)
is satisfied.
