い。(Problems to be Solved by the Invention) As mentioned above, silver thiosulfate complex salt aqueous solutions have the disadvantage of precipitation of silver sulfide during storage and turning black. Although this can be prevented by adding sulfite or sulfite water, However, it is not desirable as a cut flower because it emits a sulfurous odor.

効果を示すことを知った。(Means for Solving the Problems) The present inventor intended to stabilize a thiosulfate silver complex salt aqueous solution without using sulfite or its salt, and conducted repeated research using volatile substances. As a result, phosphoric acid, phosphorous acid, boric acid, metaborate, formic acid, oxalic acid, succinic acid,
Citric acid, malic acid, gluconic acid, ascorbic acid, alginic acid, histidine, lysine, guanidine, hydrazine, etc. are all ineffective or insufficient, but polyaminocarboxylic acids such as hexamethylenetetramine or ethylenediaminetetraacetic acid I learned that salt has excellent effects.

ニウム塩のような水溶性塩として用いられる。The polyaminocarboxylic acid referred to in the present invention is a chelate in which multiple amine groups are bonded via an alkylene group such as ethylene, and one or more hydrogen atoms in the water curtain of the amino group are substituted with a carboxylic acid group such as an acetate group. It means a compound having an action, and specific examples thereof include ethylenediaminetetraacetic acid, diethylenediamineacetic acid, diethylenetriaminepentaacetic acid, and the like. Polyaminocarboxylic acids are used as alkali metal salts such as sodium salts and potassium salts, or water-soluble salts such as ammonium salts.
