COMPOSITION FOR FORMING CONDUCTIVE FILM, PREPARING METHOD THEREOF AND CATHODE RAY TUBE WITH CONDUCTIVE FILM FORMED USING THEM

摘要

PURPOSE: A composition for forming a conductive film improved in transparency and film characteristics by improving bond strength and dispersability between each component of a composition and cathode ray tube equipped with the conductive film are provided which give the CRT improved in physical properties. CONSTITUTION: A composition comprises conductive black pigment fine particles, a pigment fine particle for controlling wavelength, a conductive polymer, and silicon alkoxide or one or more silica selected from its oligomer, wherein the conductive black pigment fine particles are uniformly dispersed in the network of silica sol and bonded with them such that the conductive black pigment fine particles do not coagulate and its bond strength does not weaken by pH, temperature and moisture. The cathode ray tube adopted the conductive improves contrast characteristics, has excellent color purity and exhibits high quality body color and picture quality.
