ABSTRACT:
A method of forming a colored and/or electrically conductive coating layer on a glass sheet by applying a paint containing an inorganic pigment and/or a metal powder together with a powdered glass frit and an organic liquid binder onto the glass sheet, by screen-printing for instance, so as to form a paint layer on the glass sheet surface, rendering the paint layer hard and untacky and thereafter firing the paint-applied glass sheet so as to melt the glass frit contained in the paint. The organic liquid binder comprises at least one acrylate which is selected from monofunctional acrylates and bifunctional acrylates and is polymerizable by radiation of ultraviolet rays. Hardening of the paint layer is accomplished by ultraviolet radiation of very short duration, and the polymerized acrylate can be completely burnt out at the firing step without leaving unburnt carbon which is detrimental to the coating layer.
