A composition for transparent coloration of a glass surface. The composition has fine gold (Au) particles; fine silver (Ag) particles; a fixing agent including an organic Ti compound, an organic Fe compound, and an organic Si compound; a binder resin; and an organic solvent. The relationship between the amount of gold and silver particles to the fixing agent as a ratio of the number of metal atoms is as follows: (Au&plus;Ag)/(Ti&plus;Fe&plus;Si)<&frac12;.

Glass colorant composition

A method for producing a colored and fired film formed on a substrate having an improved chemical resistance includes the steps of applying a coloring composition onto a substrate so as to form a film, coating the surface of the film with a coating agent, and firing the film and the coating agent. The coloring composition comprises ultra-fine particles of at least one precious metal selected from the group consisting of Au, Pt, Pd, Rh and Ag, a fixing agent comprising an organic metal compound, a binder resin, a glass network forming component formed of an organic compound containing at least one element selected from the group consisting of Si, B and P, and an organic solvent.
