Abstract
Abstract A paste for forming a transparent conductive film is provided. The paste comprises an organometallic compound convertible into a transparent conductive metal oxide by calcination, an organic solvent and a thickening agent characterized in that the paste further contains an organic monoazo compound difficultly soluble in the organic solvent, combustible at a high temperature and having the general formula: ##STR1## wherein X represents H, NO 2 or OCH 3 in a m- or p-position, Y represents NO 2 or OCH 3 in an o-position, Z represents OCH 3 , CH 3 or H in an o-position and W represents H or CH 3 in the m- or p-position.
