| abstract |
The purpose of the present invention is to provide: a coating composition which enables the formation of a coating easily by application or the like; a porous film and a light-scattering layer each of which has excellent heat resistance, excellent surface smoothness, excellent flexibility, a high refractive index, high light-scattering properties and a high light transmittance; and an organic electroluminescent element equipped with the light-scattering layer. It is found that a hardened article produced by hardening a composition comprising a polysilane, a metal oxide and a solvent has voids formed inside thereof. The hardened article having voids formed therein has light-scattering properties and therefore can be used as a light-scattering film. |
