  • Method for metallizing a phosphor screen for a cathode ray tube
    Patent number: 4122213
    Abstract: A method for metallizing a phosphor screen for a cathode ray tube including the steps of forming a volatilizable substrate on the surface of the phosphor screen and depositing a metal layer on the substrate, followed by heating for volatilizing the substrate, said substrate comprising a laminate of superposed layers respectively representing different organic materials having different thermal decomposition points. This disclosed method is advantageous in that the substrate can be volatilized without causing blistering of the metal layer and the formed metal layer is enabled to reflect light more effectively.
