Document Type and Number:
WIPO Patent Application WO/2015/029844
Kind Code:
A1
Abstract:
Provided are: a method by which a patterned thin film having high refractive index and high transparency can be easily produced in a short time; and a thin film having high refractive index, which is produced by this method. A method for producing a thin film, which comprises: a first step for forming a coating film on a substrate using a sol that contains a metal oxide modified with a phosphorus compound represented by formula (1) (in formula (1), R1 represents a hydrogen atom, an alkyl group, an alkynyl group, an alkenyl group, an aryl group, an aliphatic heterocyclic group or an aromatic heterocyclic group; R2 represents a divalent organic residue; and n represents 1 or 2); a second step for curing the coating film on the substrate, which is obtained in the first step, by irradiation of light; and a third step for providing the cured product, which is obtained in the second step, with energy by heating and/or irradiation of light.
