A novel class of stabilizing compounds for phosphor screens

摘要

A phosphor screen is provided, characterised in that said screen comprises at least one organozinc compound corresponding to the following general formula I : <CHEM> wherein : A = either carbon or phosphorus Y = -OR<6> , -NR<7>R<8>, alkyl or aryl, wherein R<6>, R<7> and R<8> each independently represent a substituted or unsubstituted alkyl- or aryl group, or wherein R<7> and R<8> together form a ringstructure n = 1 when A is carbon n= 2 when A is phosphorus. sai
