摘要:
A method for producing a silver salt of an organic acid, which comprises steps of reacting (1) a solution containing silver ions in water or in a mixture of an organic solvent and water, with (2) a solution or suspension containing an alkali metal salt of an organic acid in water, in a mixture of an organic solvent and water, or in an organic solvent to prepare a silver salt of an organic acid, and removing a byproduct salt by a desalting operation, wherein a dispersing agent having a molecular weight of 3000 or less is added and dispersed during a time period of from before the reaction to before the desalting operation. There is provided a method for producing a silver salt of an organic acid, which can provides low fog, high sensitivity and high concentration of blackening when it is used for photothermographic materials, and is suitable for the production of photothermographic materials having low haze and less image degradation after storage.

摘要:
A silver halide photographic material comprising a support having provided thereon a silver halide emulsion layer, in which said silver halide emulsion layer contains at least one sensitizing dye selected from the group consisting of a compound represented by formula (I): ##STR1## and a compound represented by formula (II): ##STR2## and at least one of said silver halide emulsion layer and other hydrophilic colloidal layers contains a dye represented by formula (III): ##STR3## wherein the substituents of the formulas (I), (II) and (III) are as described in the specification. The photographic material exhibits excellent performance properties in terms of sensitivity to light emitted from an Hc-Ne laser or an LED, safety from safelight, and freedom from color remaining after processing.
摘要:
It is an object to provide an image reading apparatus, an image reading method, and a program, in which in the case of reading both of a reflecting original and a transmitting original by one image reading apparatus, an average scanning time in the scan of a plurality of number of times can be shortened without increasing costs. In the image reading apparatus, whether the read original is the reflecting original or the transmitting original is discriminated based on a part of data read as a reflecting original by a reflecting original reading unit. If it is determined that the original is the transmitting original, the original is read as a transmitting original by a transmitting original reading unit. If it is determined that the original is the reflecting original, the data which has been read before is used.
