  • Process for metallizing phosphor screens
    Patent number: 5874124
    Abstract: A process for the metallization of phosphor screens is disclosed. The process includes the steps of coating all aqueous dispersion of a poly(hydroxyalkanoate) on a phosphor screen, allowing the screen to dry, optionally heating the screen to form a cohesive polymeric coating, depositing a layer of metal upon the coated screen to form a composite, and heating the composite to a temperature above the decomposition temperature of the poly(hydroxyalkanoate) in order to decompose and/or volatilize the film coating.
