A self-supporting or supported phosphor screen or panel

摘要

A screen, comprising a self-supporting or supported phosphor layer with phosphor particles (PP) dispersed in a polymeric binder (B), said phosphor particles (PP) being present in said binder (B) in a volume ratio PP/B of at least 80/20 is provided wherein the polymeric binder comprises at least one polymer (P) having a Tg ≤ 0 DEG C, an average molecular weight (MGavg) between 5000 and 10<7>, being soluble in ethylacetate for at least 5 % by weight (% wt/wt) and a self-supporting layer of said polymer P comprising 82 % by volume of phosphor particles and having a tickness so has to comprise 100 mg of phosphor particles per cm<2>, has an elongation at break of at least 1 %. The screen or panel shows low screen structure mottle and a very good compromise between speed and resolution.
