ELECTRICALLY CONDUCTIVE PIGMENTARY COMPOSITION AND PREPARING METHOD THEREOF

摘要

PURPOSE: A method for producing an electrically conductive pigmentary composition comprising a sulfone group-containing dispersing agent and a soluble conductive polymer-containing mixed solvent is provided which gives the title composition useful for manufacturing a CRT. CONSTITUTION: A composition comprises 0.3 to 30% by weight of a sulfone group-containing dispersing agent and 0.24 to 1.2% by weight of a soluble conductive polymer-containing mixed solvent based on the total weight of a composition, wherein an average particle size of the dispersed pigment particle is 50 to 300nm and the pigment is one or more selected from organic or inorganic pigments and dyes. The composition forms no coagulation between fine particles of a composition and is excellent in electrical conductivity.
