摘要

PURPOSE: To provide a composition which is effective for conductive coating for back light of an automobile by blending the silver granular material, a lead-free glass frit, and the organic liquid medium at a specified ratio. ;CONSTITUTION: This silver-containing conductive coating composition contains the following (a)-(c) components. (a) a silver granular material selected from a group of silver powder, silver flakes and the mixture thereof at about 40-90 wt.%; (b) a lead-free glass frit, having a following composition at about 4-12 wt.%. ZnO at 13-18 wt.%, SiO₂ at 18.0-25.0 wt.%, ZrO₂ at 2.4-3.5 wt.%, B₂O₃ at 7.5-12.5 wt.%, Na₂O at 3.0-6.0 wt.%, Bi₂O₃ at 35.0-46.0 wt.%, TiO₂ at 1.0-2.5 wt.%, and Al₂O₃ at 0-1.0 wt.%, (c) A liquid organic medium, which forms dispersion material of the silver grains and the glass frit and which has a function for facilitating application of the composition to the support, at about 7-40 wt.%. Furthermore, colorant, color-adjusting agent, rheology adjusting agent and other additive components can be blended in the composition.;COPYRIGHT: (C)1995,JPO
