摘要： A photostimulable phosphor of which the emission intensity at the stimulation wavelength of 550 nm is higher than the emission intensity at the stimulation wavelength of 600 nm, characterized in that said phosphor is a divalent europium activated barium fluorobromide containing as codopant samarium, and wherein the terminology barium fluorobromide stands for an empirical formula wherein (1) a minor part of the barium (less than 50 atom %) is replaced optionally by at least one metal selected from the group consisting of a monovalent alkali metal, a divalent alkaline earth metal other than barium, and a trivalent metal selected from the group consisting of Al, Ga, In, Tl, Sb, Bi, Y, and a rare earth metal selected from the group consisting of Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, (2) a minor part (less than 50 atom %) of the bromine is replaced by chlorine, and/or iodine, and (3) wherein fluorine is present stoichiometrically in a larger atom % than bromine taken alone or bromine combined with chlorine and/or iodine.

摘要： A method for recording an image of ionizing radiation comprising the steps of:(1) image-wise exposing to ionizing radiation an element containing at least one phosphor which converts said ionizing radiation into photochemically active radiation,(2) image-wise exposing a recording material to the thus obtained photochemically active radiation, said recording material containing at least one non-luminescent substance or poorly luminescent substance by means of which through said photochemically active radiation at least one compound is produced forming in said recording material or by transfer into a receptor element a latent luminescent image or by means of which through said photochemically active radiation (a) compound(s) is (are) formed that is (are) allowed to transfer from the recording material into a receptor element to form therein by chemical reaction a latent luminescent image,(3) exposing said latent image to radiation stimulating the fluorescent light emission of the formed luminescent compound(s), and(4) detecting a pattern of fluorescent light emitted by said latent image.

摘要： Process for forming a halftone multicolor pattern which comprises in sequence given the following steps:(1) scanningwise exposing a multicolor original attached to a rotating scanner drum to produce series of electrical signals that are fed into a computer,(2) exposing in a single scan separate black-and-white light-sensitive silver halide emulsion layer materials under the control of the computer in accordance with said signals,(3) developing the exposed silver halide emulsion layers with a hardening or tanning developing agent producing a negative or positive silver selection image that can be used as intermediate original in the production of a printing plate, a pattern of oxidized hardening developing agent being imagewise transferred during development from the emulsion layer onto a hardenable non-photosensitive colored gelatin layer originally carried on a temporary support or carried directly on a permanent support,(4) producing a colored relief image by wash-off processing of said colored gelating layer, and(5) assembling the colored relief images into a multicolor pattern on the same permanent support.
