<P>PROBLEM TO BE SOLVED: To restrain thickening and gelling in the process in which glass dielectrics powder having specific surface area over 1.5m<SP>2</SP>/g and basicity over PH8.5 is dispersed with binder resin, in manufacture of a dielectric paste for a plasma display. <P>SOLUTION: A dielectric paste contains indispensable ingredients, i.e. glass dielectric powder, binder resin, organic dispersant compound having acidic group and organic solvent. As a result, the organic dispersant compound 14 is adsorbed by the glass dielectric powder 10 and the binder resin 11 in hydrogen bonding, so that the glass dielectric powder 10 and the binder resin 11 are prevented from absorbing each other, thereby expediting dispersing. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
