Abstract

PURPOSE: To make the improvement of adhesive power, with a fixing process eliminated of photosensitive resin, by mixing a photosensitive binding agent in the photosensitive resin mainly composed of diazonium salt to be applied to the face panel.
CONSTITUTION: The material, where a little amount of photosensitive binding agent (for instance, inorganic bichromate ammonium, organic diazo resin, benzene chloride diazonium salt, etc.) is previously mixed into a photosensitive resin mainly composed of diazonium salt, is applied to the inner surfaces of face panel to construct a film. In this way, because of a light reaction in the exposure place of the film, the adhesiveness, resulting from a decomposition of the diazonium salt, and the insolubility for the water, resulting from a cross-linked binding made between the resin and the binding agent, are simultaneously generated, therefore, the fixing process, as usually made by an ammonium gas, is made unnecessary, as well as with a forming made capable of the resin film, that can fully withstand also the cleaning process further with a big power of adhesion to phosphor powder.
