Patented Feb. 2, 1932 UNITED STATES PATENT OFFICE BODOLPHE BERTHON, OF NEUILLY, FRANCE, ASSIGNOR, BY MESNE ASSIGNMENTS, TO
xrsmm conronnrron, on NEW YORK,
N. Y., A CORPORATION OF DELAWARE FOB COLOR CINEMATOGRAPHY Application filed June 26, 1928,,Serial No. 288,499, and in France July 2, 1927.
The methods of cinematography in colours.
' modification has the effect 0 permitting negatives to be obtained that are suitablefor printing positives, as desired,.by projection.
This modification consists in incorporating into the sensitive emulsion a substance adapt ed to prevent an difiusion of light'from reflection on the a jacent grains of bromide or of any other silver salt employed, so that only such rays as have directly passed through the retracting elements of the backing can-attack the silver salt while the reflected rays are deprived of all photographic activity. The sub stances to be used are generally black, brown or yellow colouring agents, but I can also use certain emulsified salts such as silver chromate. Whatever the substances used, they must be liable to complete elimination by means or suitable baths The panchromatic emulsions intended for obtaining negatives should utilize, preferably, dark colouring agents such as indulines; while the positive emulsions, the normal sensitiveness of which is limited to blue radiations, may utilize a yellow colouring agent such as tetrazine. In both cases the colour-- ing agent acts by subduing the reflected rays more energetically than the transmitted rays.
If insoluble salts are added to emulsions, such addition must be made to the emulsion itself previous to the latter being spread on the backing. If, on the contrary, colouring agents are used, they may, as desired, either be mixed with the emulsion or used afterwards to dye the gelatine of the";filin' by wetting. i For the panchromatic film? the dyeing may be efiected either before or after anchromatization, if the latter is itself effected by wetting.
Films so obtained are specially applicable to methods or processes which involve the use of films having linear microscopic elements, such films being intended for printing by optical obliteration of the network on projection. They are applicable also to processes involving the use of films gofl'ered with picots, specks or dots, as, for example, the socalled Keller-Dorian method. Lastly, they are not limited to cinematography but are serviceable for all and any photographic processes in which lenticular nets are employed.
The invention Will be more fully understood rom the accompanying drawing, the single figure of which is a sectional view of a fragment of film on a greatly enlarged it will print this layer, but a part of the ray will be reflected, first according to line 2 and then again, at the gofi'ered surface, according to line 3, and it will form an image at D which is a duplicate of image D. Two further reflections then occur accordin to lines 4 and 5, and there is danger of a t ird image 1) of the point D being formed.
It will be seen, therefore, that it is of great importance to render the reflected rays 2, 3, 4 and 5 non-actinic, in order to eliminate the formation of images D and D".
I claim as my invention:
1. A color motion picture film having a flexible base supporting a single layer of emulsion on one side thereof and having the film and to transmit it to the emulsion, and jorated therei'nf9 said emulsion having inco a substance which will ten to prevent the reflection of actinic rays transmitted to the emulsion through the base.
2. A color motion flexible base supporting a single layer of picture film having a a menses emulsion on one side thereof anti heving the other side provided with a, multiplicity of refracting elements, said other side heing so disposed as to receive'the light striking the s film and to transmit it to the emulsion; and said emulsion having incorporetefi therein a coloring agent which will tend to prevent the reflection of eetinic reys transmitted to the emulsion through the losse. to 3. A color motion picture film having at flexible losse supporting e single leyer of emulsion on one side thereoi and having the other sfle provided with e, multiplicity of retracting elements snfi other sidle being so 115 disposfi as to receive the light striking the film and to transmit it to the emnkion, end said emulsion having inoorporetecl therein an emulsifiecl salt which will. tenol to prevent the reflection of aetinic rays trensrnittedl to 2o the emulsion through the heseu in testimony whereof I my si metnre.
