  • Luminescent article with high pigment to binder ratio and manufacture thereof
    Patent number: 5789021
    Abstract: 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.

  • Luminescent article with high phosphor to binder ratio and manufacture thereof
    Patent number: 5569530
    Abstract: A luminescent article comprising a self-supporting or supported layer of phosphor particles dispersed in a binding medium and a protective coating thereover wherein the binding medium consists essentially of one or more hydrogenated styrene-diene block copolymers, having a saturated rubber di-block or tri-block having a styrene endblock on respectively one or both sides of the di-block or tri-block, as rubbery and/or elastomeric polymers. The ratio by volume of phosphor to binding medium is more than 70/30 and preferably more than 85/15. By using the hydrogenated diene copolymers which are rubbery and/or elastomeric polymers, the phosphor layer has improved elasticity, high protection against mechanical damage and thus high ease of manipulation and high pigment to binder ratio without deterioration after frequent reuse.

  • Radiographic screen
    Patent number: 5334842
    Abstract: A radiographic screen comprising (1) a metal or hydrophobic resin support, (2) a layer comprising a fluorescent phosphor dispersed in an organic polymeric binder and (3) an optionally present outermost organic polymer coating protecting said phosphor layer against abrasion, characterised in that the edges (side surfaces) of said screen are covered with a polymer material being formed essentially from a moisture-hardened polymer composition.
