Title: SOLUTION FOR MAKING A RESIN FILM AND ITS APPLICATION AT SCREENS OF CRTs
Abstract:
A solution for making a resin film contains at most 5 % by weight, preferably 1 % by weight, of α-carbon methyl group polymer. By the solution, the combustion temperature can be lowered down, and the resin film can be completely volatilized without upward swelling of the aluminum thin film during the burning or baking step owing to the solution formed by the α-carbon methyl group polymer. Specifically, also in the method for dry electrophotographically manufacturing a screen of a CRT, the conductive layer, the photo-conductive layer, and the resin film can be completely volatilized without the upward swelling and unfastening of the aluminum thin film during the burning step in a frit furnace for sealed-assembling the panel and the funnel, so that the plane reflectivity of the aluminum thin film is improved and thus the picture quality of the CRT is greatly improved.
