Abstract
Silver-containing conductive coatings are provided. The coatings are prepared from compositions comprising silver particulate material, a low firing lead-free glass frit and a liquid organic vehicle. The composition is coated on a substrate and fired to fuse the silver-containing conductive coating to the substrate. The coatings find particular use in the field of automotive backlights. The coatings are of special value in eliminating solder wet through migration.
