Abstract:
1. A process for producing a glass coated with a heat reflecting colored film, which comprises: a step of laminating a first layer containing at least 60 mass % of iron, based on the total metal amount, on one surface of a glass substrate, by sputtering by means of a metal oxide target containing iron oxide, or by sputtering by means of a metal target containing iron, chromium and nickel as components in a sputtering gas atmosphere containing an oxidizing gas, a step of laminating a second layer containing at least 60 mass % of cobalt, based on the total metal amount, on the first layer, by sputtering by means of a metal target containing cobalt in a sputtering gas atmosphere containing an oxidizing gas, or by sputtering by means of a metal oxide target containing cobalt oxide in a sputtering gas atmosphere containing no oxidizing gas or in a sputtering gas atmosphere containing an oxidizing gas, a step of coating a ceramic color paste and/or a silver paste on the second layer, and then, a step of then carrying out heat treatment.
