Shadow mask adopting electron reflective layer, for CRT

摘要

A method for manufacturing a shadow mask adopting electron-reflection layer on the surface of the shadow mask where electron beams collide, is characterised in that the electron reflection layer is formed by spray coating a composition comprising inorganic binder and bismuth ammonium citrate solution (BACS) containing 10-50 wt.% of bismuth, in which the amount of BACS is 70 wt.% or more, and selectively heat-treating the coated layer.
