    摘要： A phosphor composition which comprises oxygen and a combination of elements satisfying the relationship:[(Hf.sub.1-z Zr.sub.z).sub.1+x Sn.sub.1-x ].sub.1-y Ti.sub.2ywherein:x is in the range of from about -0.4 to 0.952y is in the range of from 0 to 0.5 andz is in the range of from 0 to 0.5These phosphors exhibit an orthorhombic crystal structure, and are useful in intensifying screens for producing a latent image in a silver halide radiographic element when imagewise exposed to X-radiation.

    摘要： This invention relates to a composition comprising microcapsules suspended in an aqueous media, said microcapsules comprising a water immiscible material contained within an encapsulating wall of polymeric material, wherein the aqueous media contains a stabilizer comprising an anionic polymer mixture comprising a first sulfonated polystyrene polymer and a second sulfonated polystyrene polymer wherein the ratio of the weight average polymer molecular weight of the first polymer to the second polymer is greater than 2. It further relates to an imaging element comprising said microcapsules.
