PURPOSE:To provide treatment liquid which contains no cyanide, a pollutant, at all, and is capable of having instantaneous non-sensitizing property and printing without fouling of a background under a single run through a processor by containing inosithexalic acid or its salts and aluminium polyhydroxide compound. CONSTITUTION:Inosithexalinic acid and its salts can easily be synthesized by a publicly known method. The ideal range of density in the title treatment liquid is 10g/l-200g/l. The aluminium polyhydroxide compound means water-soluble aluminium hydroxide salt which stably contains colloidal alumina hydrate or basic high polymer multi-nuclear condensed ions such as [Al6(OH)15], [Al3(OH)20]<4+> and [Al12(OH)34]<5+>. The ideal range of density in the treatment liquid is 0.5g/l-10g/l. In addition to the above components, a proper amount of organic and inorganic acids as pH regulator, glycerine, etc. as wetting agent and phenol, etc. as antiseptics can be added to the treatment liquid. |
