ABSTRACT:
A novel medium for a glass enamel consists essentially of at least 50, preferably at least 80, weight percent polyether glycols, solid at room temperature, having a weight average molecular weight in the range of 2000 to 9000, the remainder of the medium being incompatible vinyl-type polymers, solid at room temperature, having a viscosity at 140.degree. C. less than 1000 cps., preferably less than 500 cps. This medium is used in a minor amount with extenders, together with pigments, stabilizers, leveling agents and other additives, as desired, to make novel glass enamels useful for non-smearing patterns on glass which is to be subsequently coated with hot resins. However, this medium is equally useful in vitrifiable systems.
