Luminescent article with high pigment to binder ratio and manufacture

Luminescent article with high phosphor to binder ratio and manufacture

A coating composition suitable for forming an adhesive primer layer on a hydrophobic polyester resin support, wherein said coating composition essentially consists of (an) addition polymerizable monomer or mixture of such monomers having dissolved therein at least one of the polymers (i) and/or (ii), wherein: (i) is a linear copolyester of isophthalic acid and at least one other dibasic carboxylic acid with an aliphatic diol, said copolyester being soluble in methyl methacrylate for at least 10 g per 100 ml at 20.degree. C., and/or (ii) is a linear polyester of terephthalic acid and/or isophthalic acid with an oxyalkylated bisphenol, said polyester being soluble in methyl methacrylate for at least 10 g per 100 ml at 20.degree. C., and wherein said composition comprises said monomer(s) acting as solvent(s) for polymers (i) and/or (ii) in a 20 to 70% by weight ratio with respect to the totality of said polymer(s) and monomer(s).

Luminescent radiographic system comprising a support, a phosphor-binder

A radiographic screen comprising a support, a layer comprising a fluorescent phosphor dispersed in a binder and a protective topcoat coated over the phosphor binder layer, wherein the edges are reinforced by a radiation cured coating obtained by curing a radiation curable composition comprising a polyester prepolymer, and a diluent mono-functional monomer.

Radiographic screen with edge-reinforcing coating

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.
