Abstract of the Disclosure This invention relates to dispersions of gold and a certain inorganic binder in an inert liquid vehicle, useful in the electronics art for producing conductor patterns adherent to substrates. Small amounts of the binder are effective in producing excellent adhesion to substrates, such as ceramic substrates. The binders comprise certain amounts of the crystalline materials PbF2, Cu2O, and CdO, in addition to a glass of, by weight, 45-52% PbO, 3-6% B2O3, 30-35% SiO2, 4-6% TiO2, 2-4% ZrO2, 0-1% ZnO, 1-4% Na2O, 0-4% CdO, and 0-2% Li2O.
