Abstract
A method and composition for manufacturing a luminescent screen assembly for a color cathode ray tube (CRT) is disclosed. The luminescent screen assembly is formed on an interior surface of a faceplate panel of the CRT. The luminescent screen assembly has a patterned light-absorbing matrix thereon. The matrix defines a first set of fields, a second set of fields, and a third set of fields. An aqueous pigment suspension is applied to the first set of fields. The aqueous pigment suspension comprises a pigment, one or more surface-active agents and at least one non-pigmented oxide particle. The at least one non-pigmented oxide particle has a size that is less than that of the pigment.
