AUGUSTE LUMIEBE AND LOUIS LUMIERE, or LYON, FRANCE.
SENSITIVE PLATE FOR COLOR PHOTOGRAPHY.
To all whom it may concern:
Be it known that we, AUGUSTE LUMIERE and LoUIs L MIERE, citizens of France, residing at Lyon, (Rhone,) France, have invented new and useful Improvements in Sensitive Plates for Color Photography, of which the following is a specification.
The invention relates to the process of. manufacture of sensitive plates for color photography, such process consisting in the interposition between the sensitive coating and said process the continuity of the screen layer interposed between the sensitive coating and its support is obtained by'fillim the interstices remaining between the colored particles with black powder. This filling is. avoided by themethod hereinafter described and illustrated in the accompanying drawing.
Figure 1 shows, on a greatly enlarged scale, the arrangement of the-colored particles after their application. to the support. Fig. 2 shows these same particles after the complementary operation for rendering the After-having spread on the transparent support,-- which maybe glass, film, paper,
etc., afl-ayer of pitchy material, there is spread a la er, as uniform as ossible, ofcolored partic es, in which layer t e grains touch other/as shown at Fig. '1. hese grains,
composed 'of fecl'ila, starch, or other analo Specification of Letters Patent. Application filed May 9.190s. Serial No. 316.011.

er to acquire the gous matter, are then brought to a suitablehygrometric condition in or necessary plasticit forthe next oppration.
In this state the-co ored coating is su mitted, at the same time as its support, to a direct pressure or-to a rolling, which crushes the suitably softened colored grains and causes them to fill the spaces so as to form, as shown at Fig. 2, a mosaic covering the support at all parts. i
This method has, over that of filling with black powder, the advantage of producing more luminous plates and of regularizing the thickness of the coating in such manner as to avoid as much as possible the difi'usiou'of The colored coating thus obtained is, as before, covered with a transparent varnish, above which is spread the sensitive coating, and the plates are utilized as before. What we claim as our invention and desire A sensitive plate for color photography comprising a sensitive coating-and a layer of crus ed colored particles interposed between the sensitive coating and the support.
In testimony whereof we have signed our names to this specification inthe presence of witnesses. AUGUSTE LUMIERE'. LOUIS LUMIERE; Witnesses:
