Abstract
A method for producing an article with a low reflection film having a low reflection film on a substrate 2, comprising applying a coating composition to the substrate 2 using an electrostatic coating method of atomizing and electrifying the coating composition so as to be attached to the substrate 2 by static electricity, and baking or drying the coating composition to form the low reflection film, wherein the coating composition contains a dispersion medium (a), fine particles (b) dispersed in the dispersion medium (a), a binder (c) dissolved or dispersed in the dispersion medium (a), and an organic compound (d) having a polar group dissolved or dispersed in the dispersion medium (a).

A method for producing a substrate with a film having fine particles dispersed in a matrix comprising Si01, the method comprising:
- preparing a coating composition comprising a dispersion medium (a), fine particles (b) dispersed in the dispersion medium (a), and a binder (c) which contains a hydrolyzate of an alkoxysilane and is dissolved or dispersed in the dispersion medium (a);
- placing a substrate on an electrically conductive substrate;
- spraying the coating composition onto the substrate from a nozzle tip of an electrostatic coating gun;
- electrifying the coating composition in an atomized state, thereby attaching the coating composition to the substrate placed on the electrically conductive substrate;
- and
- baking or drying the coating composition, thereby forming the substrate with the film.
