To increase the dispersion stability of the glass powder and suppress the occurrence of aggregation of the glass powder with the time by using the glass powder together with a binding resin and fatty acids.
The glass powder preferably softens at 400-600°C and is a mixture of lead oxide, boron oxide and silica or the like. The binding resin is preferably an acrylic resin. Thus, in the resultant membrane-forming material layer manifests excellent adhesion to the glass base material, resultantly the transfer film formed by applying the composition to the substrate film shows excellent transfer to the glass base plate. The amount of the binding resin is 5-40 pts.wt. per 100 pts.wt. of the glass powder. The fatty acid increases the dispersion stability of the glass powder and a saturated fatty acid such as octanoic acid or the like or an unsaturated fatty acid such as elaidic acid or the like can be cited. The content of the fatty acid is preferably 0.001-10 pts.wt. per 100 pts.wt. of the glass powder.
