Glass substrate with colored film fine-particle-containing solution for forming colored film and method for producing glass substrate with colored film

摘要

The present invention provides a glass sheet with a colored film that can be recycled as a cutlet raw material. The glass sheet includes a glass substrate and a colored film that coats at least part of the surface thereof. This colored film includes an alkali metal oxide, a silicon oxide, and fine particles containing carbon as their main component. The colored film functions as light-shielding films that reduce the visible light transmittance and ultraviolet transmittance.
