    摘要： A method of preparing a homogeneous, ready to use, sulfate-free, single-part color developing composition comprises the steps of:

    A) mixing in water, a color developing agent present as a sulfate salt, an antioxidant for the color developing agent, alkali metal ions in at least stoichiometric proportion to the sulfate salt, and a water-miscible or water-soluble, straight-chain organic solvent having a molecular weight of from 50 to 200, and present at a concentration such that the weight ratio of water to the solvent is from 15:85 to 50:50, to form an alkali metal sulfate in the solution, and
    B) removing the alkali metal sulfate from the solution.

    摘要： Improved one-part concentrated color developing replenishers and methods of preparation thereof comprising a photographically inert single ring heterocyclic amide. The replenisher concentrates are packaged in a single unit which upon dilution provides ready-to-use replenishing solutions for photographic materials. The concentrated replenishers are characterized by a one-part multi-phase concentrate wherein developing agents are retained in an upper phase and protected from deterioration which normally occurs in the highly alkaline lower phase.

    摘要： Black-and-white elements, such as radiographic films, can be processed in roomlight because the developing composition includes a water-soluble colorant. Such colorants are water-soluble dyes that have a maximum absorption wavelength of from 350 to 500 nm. Processing is carried out by processing the exposed element using a two-stage process in the same processing container. In the first stage, development is initiated with an opaque developing composition having a pH of from 10 to 12.5, and comprising an appropriate black-and-white developing agent, a yellow colorant, and a sulfite. After an appropriate time, a fixing agent (other than a sulfite) is introduced into the processing container to begin simultaneous development and fixing. The entire process in quite rapid, that is less than 90 seconds.

    a method of making a concentrated alkaline photo­graphic developer composition, packaged in a single part to be diluted with water to form a ready to use develop­ing solution for silver halide photographic materials, which comprises dihydroxybenzene developing agents, inor­ganic alkali agents, inorganic antioxidant agents, se­questering agents and antifoggants, characterized in that comprises the following steps:
    a) preparing an aqueous KOH concentrated solution having a specific gravity not higher than 1.110 at 20°C, b) adding to the resulting solution inorganic anti­oxidant agents which form sulfite anions (SO₃⁻⁻) in aque­ous solution, at least half in moles of which being Na₂S₂O₅ (sodium metabisulfite), in a quantity of from 0.8 to 2 moles per liter, c) adding to the resulting solution further aqueous KOH concentrated solution until the specific gravity of the resulting solution is ≧ 1.175 at 20°C, d) adding to the resulting solution developing agents in such a quantity that the molecular ratio be­tween said inorganic antioxidant agents and the develop­ing agents is from 1.5 to 4.00, and e) adding the other components of the developer com­position in such a quantity to obtain a concentrated de­veloper composition having a specific gravity higher than 1.300 at 20°C.
