ABSTRACT:
A color cathode ray tube includes an automatic convergence unit employing index elements on the reverse surface of a color-selective electrode. The paste used for forming the index elements has a composition consisting essentially of index phosphors, an inorganic adhesive and water to assure the adhesive force of the index elements onto the color selective electrode to prevent peeling of the index elements while facilitating the coating operation for formation of the index elements.
