Abstract

PURPOSE: To prepare the titled fluorescent material having improved heat resistance and luminance without lowering the reflecting properties of ultramarine pigment, by coating a blue light-emitting fluorescent material with ultramarine pigment and a cobalt-blue pigment consisting of cobalt aluminate.
CONSTITUTION: The objective fluorescent material is obtained by coating (A) a fluorescent material emitting blue light with (B) ultramarine pigment and (C) a cobalt-blue pigment consisting of cobalt aluminate. The amount of the component (B) is preferably 0.5W10wt%, based on the component (A), and that of the component (C) is preferably 5W40% of the component (B). The above fluorescent material is prepared preferably by (1) mixing a fluorescent material coated with the component (B) and a fluorescent material coated with the component (C), or (2) coating the component (A) with a mixture of the component (B) and the component (C), or (3) coating the component (A) successively with the component (B) and the component (C).
USE: For color picture tube.
