<P>PROBLEM TO BE SOLVED: To provide an optical reflection film obtained by a coating method using an aqueous dispersion slurry, the film having an excellent reflecting property, little scattering of light and high productivity, and to provide an optical reflector using the film. <P>SOLUTION: The optical reflection film includes at least one unit comprising alternately layered high refractive index layers and low refractive index layers on a support. The high refractive index layer comprises (1) a water-soluble polymer having a phosphoric acid group or its salt, or a phosphate or its salt and having a weight average molecular weight of 30,000 or less, (2) a water-soluble polymer having a weight average molecular weight of 50,000 or more, and (3) a metal oxide. <P>COPYRIGHT: (C)2013,JPO&INPIT |
