Definitions
- V 1 This invention relates to photographic deing color images in multi-color photographic velopers and particularly to accelerators for layers containing color-formers fast to diffusion, photographic developers. as disclosed in United States Patents 2,178,612;
- these amines accelerate ellent quality- 7 the development so as to cause the developing
- the developing e w th black and white agent to form the image (silver or color image) developers, for instance, solutions of hydromore rapidly than is possible without the presquinone and monomethylam ne- -p S111- ence of such amines.
- an object of the present invention to provide a black and white and color p-chlorobenzylamine developer having an increased rate of development so that the developing time is substantially GENE decreased to about one-half of the normal time.
- Example I Grams p-Monomethylamine-m-phenol sulfate 0.8 Sodium sulfite (anhydrous) 45 Hydroquinone 1.2 Sodium carbonate (monohydrate) 8 Potassium metabisulfite 4 Potassium bromide 1.5 p-Chlorobenzylamine 4 Water to make liter 1
- This tank developer gives, on development at 20 C. of the usual roll film, a soft negative in about 6-10 minutes after fixing and washing. The time required to develop a similar roll in the same developer and at the same temperature, but containing no p-chlorobenzylamine, ranges from 15 to 20 minutes. Increasing the concentration of the p-chlorobenzylamine to '7 grams per liter effects a further decrease in time.
- Example II The following developer requires 30 minutes at 20 C. to give a satisfactory degree of color development with color paper:
- the color paper utilized in the foregoing example, consists of an integral tripack emulsion coated on either the usual paper base, or a clear cellulose acetate or nitrate film base, or in some cases an opaque white film base.
- Each of the emulsion layers is sensitized to one of the primary colors of light; namely, blue, green and red.
- the top layer is blue sensitive.
- a filter layer, yellow in color and blue absorbing, lies under the top layer. Below this filter layer, lies a green sensitive emulsion layer, and below this a red sensitive emulsion layer.
- Each of the three silver-halide emulsion layers contains dye-forming compounds which unite during the development of a silver image in an aromatic amine developing agent to form a dye with the oxidation product of the developing agent.
- a yellow dye is formed in the blue sensitive emulsion; a magenta dye is formed in the green sensitive emulsion; and a cyan dye is formed in the red sensitive emulsion.
- the combination of the dye images from these three printing primaries yields the color picture.
- Suitable methods for the preparation of multicolor emulsion layers have been described in the literature relating to color photography, and
- Example III The following developer requires 19 minutes at 20 C. to give a satisfactory degree of color development with color paper:
- R is a group selected from the class consisting of methyl and ethyl groups
- n is a positive integer of from 1 to 2
- X is a negative group selected from the class consisting of nitro and halogen atoms, and the salts of said amines.
- R is a group selected from the class consisting of methyl and ethyl groups
- n is a positive integer of from 1 to 2
- X is a negative group selected from the class consisting of nitro and halogen atoms, and the salts of said amines.
- a color-forming photographic developer comprising a primary aromatic amino developing agent and a negatively substituted aralkylamine selected from the class consisting of those corresponding to the following formulae:
- R is a group selected from the class consisting of methyl and ethyl groups
- n is a positive integer of from 1 to 2
- X is a negative group selected from the class consisting of nitro and halogen atoms, and the salts of said amines.
- a color forming photographic developer REFERENCES CITED comprising a, primary aromatic amino develop- I ing agent and a negatively substituted aralkylg z Z ES i Rq i of record m the amine characterized by the following formula: p
