Abstract: There is provided a compound represented by Formula (1), and a coloring composition including the compound: wherein, in Formula (1), R0 to R3 each independently represent a hydrogen atom or a substituent, and R0 and R1, R0 and L, or R1 and L may be combined with each other to form a ring, L represents a single bond or a divalent linking group, D represents a residue in which n hydrogen atoms are removed from a compound represented by Formula (2), n represents an integer of 1 or more, provided that when n represents an integer of 2 or more, a plurality of R0's to R3's and L's may be the same or different, the compound represented by Formula (1) has at least one ionic hydrophilic group, and in Formula (2), R4 to R24 each independently represent a hydrogen atom or a substituent.

Abstract: A radiation conversion panel allows recorded radiation image information to be read therefrom with high accuracy while reliably avoiding adverse effects of residual past radiation image information that remains in the radiation conversion panel. When a radiation conversion panel storing radiation image information therein is scanned by reading light from a reading light source, the radiation image information is read from first linear electrode layers, and scanned position information is read from a first linear electrode layer of a marker. A corrector corrects presently read radiation image information based on past radiation image information and scanned position information to acquire radiation image information free from the effect of a residue of the past radiation image information.
