Definitions
- This invention relates to color photography, andrmoreparticularly :to .a process of producing multi layer color.
- negativescontaining masking images imthe cyanrand magenta layers for color correction purposes::-
- the productionof 1- color prints from' multi layer; color; negatives; the-color negative consists ofeyellow, magenta, and cyan images in the dif ferentglayers:
- The-cyan image represents thered, the: magenta imagezthe green, and the ye1'-- low image the: blue arecord: of the original subject;
- Colorrpositi've printsw or transparencies may-be obtained from sucl-icolor negatives by directuprinting: ontoa multi-la'yer color positive film or.paper;or-by-makingeolor separation negatives whichrare used for making the color positive prints.
- magenta dye image equalinvintensity to the degree to' which .themagenta dye-absorbs blue light, but oppositeiin: character, with: the yellow: dye. im-- ages
- Thesemasks or modifying images can 1 be yellowin color, assuggested by the prior art, ortheyycanr be-a neutral gray, composedof fdye or.silver.-
- Another method consists of forming masking images in the original green and red sensitive layers by a reversal processing.
- the procedure proposed, to accomplish the formation of a mask is to color develop the exposed multi-layer color film and then subject it to the action of a special fixing bath whose penetration into the depth of the emulsion layer can be controlled and the fixing action thereof limited to the upper-most blue sensitive layer.
- a special fixing bath whose penetration into the depth of the emulsion layer can be controlled and the fixing action thereof limited to the upper-most blue sensitive layer.
- an object of the present invention to provide a method for obtaining, in subtractively colored multi-layer photographic color negative materials, masking images composed of silver which correct for the color deficiencies of the cyan and magenta dye images thereof.
- a further object is to provide a method for obtaining color corrected color negative materials wherein the color correction is integrally bound with the cyan and magenta dye images.
- Bleaching i. e., converting, of all the silver negative images and any other silver, such as the colloidal silver that may be present in the yellow filter and anti-halation layer, into silver bromide by any bleach bath which does not impair the dye images already present. 4
- the bleach bath reconverts the negative silver images to silver bromide, and these newly formed silver bromide grains are light-sensitive, so that upon re-exposure and development with a developing agent containing these depth controlling reagents, the latent images of silver bromide grains form silver images.
- the sensitivity of the reformed silver bromidegrains is very much less than the sensitivity of the residual silver bromide left after color-development. Hence. ample sensitivity differential exists between the silver bromide formed by the rehalogenation of the negative silver image and the residual silver bromide to allow the formation of latent images only in the residual silver bromide.
- Example I A multi-layer photographic color film, such as prepared according to U. S. Patents 2,179,228; 2,179,239; 2,186,849; 2,220,187 and 2,357,388, was exposed to a colored object and then developed for 15 minutes in a color developer of the following composition: a
- the exposed silver-halides present in the cyan and magenta layers were reduced to metallic silver thereby forming in each such layer a masking image composed of metallic silver to provide for color correction in printing. No development took place in the yellow (uppermost) layer.
- Example II Example II was repeated with the exception that after the bleaching treatment and re-exposure, the film was further developed in a depth developer of the following composition:
- the developed film was washed, fixed and dried in the usual manner.
- Example III Example I was repeated up to and including a bleaching treatment and re-exposure of the bleached film. The re-exposed film was then developed in a depth developer of the following composition:
- li/Idlti-layer photographic film such a prepared according to United :Stats 'P-atiits- 22692158 66, 44 3; 2,272 ,191 2,284,877; 2,289f803; 253'04940; 2,3l1 ,020; 2,350,380; 2,397;- '864'-*5 6---and 7, -and the' like can also be processed into color negatives-"containing masking images in a'c'cordance with 'tl'ie present invention.
- improvement which comprises developing thereexposed silver-halide layers to positive silver images only in the magenta and cyan layers in a black and white developer containing from 0.02 to 0.4 gram per liter of developer of a, depth controlling reagent consisting of Z-mercapto-benzthiazol.
