Definitions
- the sharpness and resolution of photographic images produce with photosensitive layers of silver halide emulsions are impaired by the light scattering caused by the silver halide grains. This elfect can be reduced by colouring the photosensitive layers with dyestuffs which absorb light in the spectral range to which the emulsion is sensitive, which dyestufis may then be removed after exposure.
- the harmful effect of the scattered light is attenuated owing to the longer path which the light has to traverse than the light which falls directly on the silver halide granules to produce the image.
- Dyestuffs particularly when used for colour photography, must be practically completely decolorised or removed subsequently because even a faint stain of residual dyestuif can considerably impair the quality of a colour image.
- Many dyestuffs which are decolorised by the agents used in the processing baths, e.g., by sodium sulphite or potassium ferricyanide are useless because mostly the decolorisation is incomplete. It is therefore advantageous to use dyestuffs which can be washed out of gelatine layers.
- Dyestuffs which are suitable for absorbing the scattered light particularly in the red sensitive layer of multiple layer photographic materials without having a desensitising action and which may be removed quantitatively from gelatine layers by washing with water are by far rarer than absorbing dyestuffs for the layers which are sensitive' to green or blue.
- red sensitive layer dyestufis which are easily soluble in water, particularly for colour photographic multi-layer copying materials which have a strong absorp- 'tive action in the whole red region of therspectrum, especially in the region of maximum red sensitivity, which.
- the absorbing dyestuffs according to the invention are added in aqueous solution, preferably in quantities of 0.5 to 5 grams per gram atom of silver in the form of silver halide to the gelatine-silver halide emulsions before casting. Based on the quantity of silver halide in the emulsion, we have found that for about 0.5 to about 10 g. of dye per gram mole of silver can be employed, although higher or smaller amounts of dye can be used depending upon particular conditions.- Owing to the high watersolubility of the dyestuifs and their low aflinity to gelatines they become distributed over adjacent layers so that it may be advantageous to colour not only the red sensitive emulsion layer but also the other emulsion layers before casting.
- the dyestuffs which are uniformly distributed in all the layers, in addition reduce the intensity of reflected light.
- FIGURE 1 shows the preparation and application of the dyestufis (A, B, C) according to the invention.
- FIGURE 2 shows the spectral distribution of red-sensitivity of the photographic layer sensitised with dyestuff Rr 1953 (Fiat Final Report No. 943), with themain maximum of red sensitisation in the region between 680 and 710 III/1., which is characteristic for multi-layer copying materials for colour photography.
- Rr 1953 conforms to the following formula:
- Example 1 31.8 g. of 1,2-diaminonaphthalene-3,7-disulphonic acid was dissolved by gently heating it in ml. of water and adding 80 ml. saturated sodium acetate solution. 32.4.g. of ferric chloride dissolved in 100 m1. of water were then gradually added with stirring at'30 C. to the yellow solution. After allowing the mixture to stand at room temperature for one hour, the" precipitated dyestulf (A) was isolated by suction filtering and digested twice with a small quantity of 1 5% hydrochloric acid and then filtered by suction until dry in air and subsequently completely dried at 70. 12 g. of dark green powder readily soluble in water to give a clear'solution with a brilliant blue-green colour were obtained.
- This emulsion was used for the middle layer of a three.
- the lowest layer applied on a cellulose triacetate foil consisted of a blue sensitive gelatine-si-lver bromide emulsion with yellow colour coupler, andthe uppermost layer was a green sensitive gela-.
- tine-silver chlorobromide emulsion with magenta colour coupler contained about 42 mg. of dyestufi (A) per mP. film was composed without the addition of absorbing dyestuff.
- Example 2 50 g. of 1,Z-diaminonaphthalene-S,7-disulphoni-c acid was dissolved by heatingin 350 ml. of water and 49 g. potassium acetate were added. 170 cc. of a 3 1% ferric chloride solution were stirred at into this intensely coloured yellow solution. After stirring for one hour at room temperature, the precipitated dyestuff (B) was filtered off by suction, pu-rifiedby digesting with 20%.
- a three layer positive colour-film was built up as in Example 1, except that all the layers contained 0.6 g.
- V Example 3 V 35.4 g; l,Z-diaminonaphthalene-f;,6-disulphonio. acid used such as cyanmes, 'merocyanines, complex (trinuclear) and 29.4 g. potassium acetate were dissolved together in 200 ml. water. 32 g. of ferric chloride dissolved in 100 ml. water were added at 35 with stirring.
- the product was filtered after 15 'minutes and the filtrate was treated with 1 /2 times its volume of alcohol and the precipitated dyestufi (C) was separated by suction filtration, washed with about 50 ml. of 96% alcoholand dried in a drying oven at 70. 37v g. of a greenishblack powder readily soluble in water to give a clearblue green solution were'obtained.
- the photographic. silver halideemulsions can be optically sensitised or unsensitised-
- Emulsions ofsilver chloride'orsilver chloro bromide are. preferred.
- our invention is particularly directed to .the ordinary employed silver halide gelatine emulsions, binding agents other than .gelatine, e.g.',' polyvinyl alcohol or. cellulose materials; .such 1 as hydrolyzed cellulose acetate; carboxymethyl. cellulose I or the like which haveno; deleterious etlect upon the lightsensitive materials, can beemployed aloneor in comb1nation.with.gelatine;. i g
- the emulsions prepared in accordance with our inven- 'tion can. be coated in the usual manner uponany suitable material with absorbing dyestuft had a resolution of p I lines/mm. and much better contrast.
- the blue-green colour-coupler used in the emulsion according to the invention is not especially critical and is selected according to the requirements of the particular copying material in which the emulsion is to be used.
- a photographic silver halide gelatine emulsion optically sensitised to the red region of the spectrum containing from about 0.5 to 10 g. per mole of silver halide of a water soluble dye, said dye being a reaction product of ferric chloride with 1,2-diaminonaphthalene disulphonic acids, said reaction product having its maximum absorption in the red region of the spectrum.
- a photographic element for subtractive colour photography comprising a support having coated thereon a plurality of silver halide emulsion layers, one of which is sensitive to the blue region of the spectrum and contains a colour-forming compound capable of coupling with the oxidation products of a colour developer to produce a yellow image, one of which is sensitive to the green region of the spectrum and contains a colour-forming compound capable of coupling with the oxidation products of a colour developer to produce a magenta image and one of which is sensitive to the red region of the spectrum and contains (1) a colour-forming compound capable of coupling with the oxidation products of a colour developer to produce a cyan image and 2) from about 0.5 to 10- grams per mole of silver halide of a water soluble dye having its maximum absorption in the red-light region of the spectrum, said dye being a reaction product of ferric chloride with 1,2-diamiuonaphthalene-disulphonic acid.
