Title:

TRANSPARENT CONDUCTIVE FILM, TRANSPARENT CONDUCTIVE BASE MATERIAL, AND CONDUCTIVE MATERIAL

Document Type and Number:

WIPO Patent Application WO/1994/013851

Kind Code:

A1

Abstract:

A transparent conductive film for office automation equipments, which has practically sufficient electrical conductivity and light transmittance and excellent wet heat resistance and etchability. The conventional transparent conductive films comprising ITO have drawbacks that the wet heat resistance is poor and the conductivity and light transmittance will lower with time. The invention aims at solving these problems and provides a transparent conductive film comprising a substantially amorphous oxide containing indium and zinc as the principal cationic element or another amorphous oxide containing indium and zinc as the principal cationic element and having an atomic ratio, In/(In+Zn), of 0.50 to 0.90.
