Adhesion between phosphor and topcoat layers of an X-ray intensifying screen
摘要
An improved X-ray intensifying screen element containing a topcoat layer comprising an acrylonitrile-styrene copolymer optionally mixed with a carboxylated acrylic polymer and an active, phosphor layer having an adhesion promoting amount of a soluble, inorganic salt as described. The improved element exhibits strong adhesion between the topcoat and active layers and is eminently suitable for the rough handling encountered when these elements are used in autochangers and the like.
