COMPOSITON FOR FORMATION OF CONDUCTIVE MEMBRANE AND CATHODE RAY TUBE ADOPTING THE CONDUCTIVE MEMBRANE FORMED BY USING THE SAME

摘要

PURPOSE: A composition for forming a conductive membrane is provided, which provides membrane hardness and contamination preventing function as well as an excellent conductive property and contrast property. Also, a cathode ray tube containing the conductive membrane formed by using the composition is provided. CONSTITUTION: The composition contains; (i) conductive black pigment; (ii) conductive polymer; (iii) binder that is alkylalkoxysilicate: RnSi(OR')4-n, wherein, R is an independently alkyl group having carbon number of 1-4, OR' is an independently alkoxy group having carbon number of 1-4 and n is 1 or 2; (iv) solvent; and (v) optionally at least one conductive agent selected from the group consisting of metal corpuscle and metallic oxide corpuscle. The cathode ray tube contains; (i) panel; and (ii) the conductive membrane formed at the outside of the panel.
