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.

Adhesion between phosphor and topcoat layers of an X-ray intensifying

Performance characteristics for an X-ray intensifying screen are improved by use of an acrylonitrile/styrene copolymer composition as the protective topcoat. The resulting intensifying screen is well suited for use in automatic X-ray changer systems.

X-ray intensifying screen with improved topcoat

X-ray intensifying screen comprising, in order, support; fluorescent phosphor containing active layer; and protective topcoat which is a flexible film of a fluorine containing polymer, the topcoat being energy treated under oxidative condition, e.g., corona discharge, etc., and having an antistatic agent applied thereto, e.g., from a solution containing at least 0.1% by weight of an anionic, cationic, nonionic or amphoteric antistatic agent. The X-ray intensifying screens have improved resistance to static.

A method for concomitant particulate deposition in electroless plating wherein objects to be plated are subjected to tumbling during the plating process.

Method and apparatus for concomitant particulate deposition in

This invention is a method for depositing on an article a coating containing at least one member of the group metals and metal alloys plus particulate dispersed diamond comprising contacting the surface of the article with a stable electroless plating bath consisting essentially of an aqueous solution of soluble constituents of the group, electroless reducing agent therefor, a suspension of diamond particles therein and a stabilizer, and maintaining the diamond particles in suspension throughout the bath during the coating of the article for a time sufficient to produce a preselected depth of coating on the article, and the coated article per se.
