Abstract

A method for manufacturing a shadow mask adopting electron reflection layer on the surface of the shadow mask where electron beams collide, is characterized in that the electron refection layer is formed by spray coating a composition comprising inorganic binder and bismuth ammonium citrate solution (BACS) containing 10-50wt% of bismuth, in which the amount of the BACS is 70wt% or more, and selectively heat-treating the coated layer. The method is simple in application and greatly reduces hole-blocking and thermal transformation, to improve color purity of a reproduced image and thereby enhance the quality of the color cathode ray tube.
