<p>In accordance with the present invention a luminescent article is provided which luminescent article comprises a self-supporting or supported layer of phosphor particles dispersed in a binding medium and a protective coating thereover characterised in that the binding medium comprises one or more rubbery and/or elastomeric polymers, in that the ratio by volume of pigment to binding medium is at least 70:30 and at most 92:8 and the packing ratio is less than 67 %. By said rubbery and/or elastomeric polymers the phosphor layer has improved elasticity of the screen, high protection against mechanical damage and thus high ease of manipulation and high pigment to binder ratio. Moreover no compression manipulation is necessary to get a thinner coated phosphor layer with reduced voids, and nevertheless a better image quality, i.a. sharpness, is obtained. One or more antioxidants may be present.</p> |
