Definitions
- a fifth bath incorporating glycerine for prevention of emulsion cracking may be used to increase the life and permanence of the finished product.
- the said materials are rapidly passed through a series of four baths.
- the solutions in the baths are maintained at an elevated temperature of from 75 to 125 F. by thermostatically controlled means well known in the art.
- the elevated temperatures accelerate the developing and fixing reactions. It has been found possible, by employing the compositions of the present invention, to have the photosensitive material traverse all of the four baths in less than one-halfminute.
- the speed of a high-alkaline hydroquinone development is achieved, while greatly extending the activity and useful life of the solution.
- the first bath serves to impregnate the photosensitive material with developing agents at a pH which will ensure long solution life and stability.
- the pH necessary for rapid development is provided by the second bath.
- the hydroquinone is thus not subject to in situ oxidation and only the small quantity of hydroquinone carried over into the alkaline second bath is subject to chemical reaction.
- a preferred first bath solution according to the present invention consists of the following:
- the ethylene glycol increases the solubility of the hydroquinone in the solution thereby increasing the amount of hydroquinone which will be absorbed into the photosensitive material.
- a preferred second bath solution according to the present invention consists of the following:
- the developing time is of the order of 14 seconds due to the combination of the high concentration of the first solution, the high pH of the second solution and the elevated temperatures (75 to F.) of both solutions.
- a preferred fixing solution according to the present invention consists of the following:
- Another fixing solution according to the present invention consists of the following:
- a preferred fourth bath consists of:
- thiosulfate in the final bath in dilute quantity provides sufficient complexing to tie up free silver ionsand still wash the reaction by-products in sufficient quantity to provide good short-term fixing.
- a fifth bath may be employed.
- a satisfactory fifth bath to give the photographic materials archival quality comprises the following:
- a method for increasing the speed for developing exposed photosensitive materials comprising, in combination, developing said materials in two different baths, the first bath containing 86.73 percent by weight of water, 0.70 percent by weight sodium bisulfite, 0.02 percent by weight of benxotriazole, at least 4.71 percent by weight of hydroquinone, 7.73 percent by weight of ethylene glycol, 0.11 percent by weight of sodium sulfite; the second bath containing 88.09 percent by weight of water, 0.65 percent by weight of potassium bromide, 5.87 percent by weight of sodium sulfite, 1.47 percent by weight of trisodium phosphate, and 3.92 percent by weight of sodium hydroxide; then fixing said material by passing them through a third bath containing some 29.14 to 35.72 percent by weight of ammonium thiosulphate (50 percent), 12.2 to 17.86 percent by weight of ammonium thiocyanate (50 percent), 46.42 to 54.75 percent by weight of water; and washing said materials by passing them through a fourth bath
- said third bath contains also from 0 to 2.78 percent by weight of monosodium phosphate and 0 to 1.21 percent by weight of sodium sulfite.
