Moisture resistant phosphorescent X:ray reinforcement screens - having phosphorescent halogen contg. particles treated with organo-metallic cpds

Halogen-contg. phosphorescent particles are rendered less susceptible to the deleterious effects of moisture by treatment with >=1 organometallic cpd. (I). (I) is pref. applied to the surface of the particles using a suitable binder, (resin e.g. ABS) e.g. by milling the components together in an...

description Halogen-contg. phosphorescent particles are rendered less susceptible to the deleterious effects of moisture by treatment with >=1 organometallic cpd. (I). (I) is pref. applied to the surface of the particles using a suitable binder, (resin e.g. ABS) e.g. by milling the components together in an organic solvent. Process is esp. useful for making phosphorescent X-ray reinforcement screens less sensitive to loss of fluorescing capacity due to the effects of moisture. Suitable (I) are e.g. water insoluble metal carboxylates, tin mercaptides, triphenyl antimony, triphenylbismuth or tetraphtenyltin.
