TRANSPARENT INSULATING FILM FORMING PASTE

摘要

PURPOSE:To obtain the titled paste which gives a coating film having a high strength by screen printing, by adding a tackifier to an org. solvent soln. containing an organozirconium compd. contg. oxygen directly attached thereto and an organosilicon compd. CONSTITUTION:A paste is obtd. by dissolving a mixture of an organozirconium compd. contg. oxygen directly attached thereto and an organosilicon compd. in an org. solvent and adding a tackifier thereto. To enable a transparent insulating film to be formed by screen printing, the silicon compd. and the zirconium compd. must be stably dissolved in a high-boiling (180 deg.C or above) org. solvent and converted perfectly into oxides at a baking temp. (450-700 deg.C) of the paste. Examples of such compds. are vinyltris(2-methoxyethoxy)silane and tetraacetylacetonatozirconium. Examples of the tackifiers are ethylcellulose and nitrocellulose.
