An overglaze ink comprising (a) 55 to 70 weight % of a glass composition, the glass composition comprising (1) 15 to 43 weight % of a main glass component selected from the group consisting of BaO, SrO and SrO+BaO, (2) a glass forming component comprising 34 to 45 weight % B2O3 and 0 to 6 weight % SiO2 (3) 0 to 2 weight % of a colorant selected from the group consisting of Cr2O3, CoO and NiO, (4) 7 to 20 weight % of a thermal expansion modifier selected from the group consisting of ZnO, Al2O3, TiO2 and mixtures thereof, and (5) 1 to 7 weight % of a dopant comprising one or more of the following: ZnF2 having a weight % of 0 to 5, Li2O having a weight % of 0 to 2, Na2O having a weight % of 0 to 2, K2O having a weight % of 0 to 2, LiF having a weight % of 0 to 2, NaF having a weight % of 0 to 2, KF having a weight % of 0 to 2, BaF2 having a weight % of 0 to 2, Na2SiF6 having a weight % of 0 to 2, PbO having a weight % of 0 to 3, V2O5 having a weight % of 0 to 2, BiO3 having a weight % of 0 to 2, and (b) 30 to 45 weight % of an organic vehicle. The overglaze ink is useful in constructing rigid multilayer integrated circuits on substrate materials, particularly alumina. |
