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 T.sub.g .ltoreq.0.degree. C., an average molecular weight (MG.sub.avg) between 5000 and 10.sup.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 tickhess so has to comprise 100 mg of phosphor particles per cm.sup.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.
