GERMAN PATENT OFFICE

It is known to produce color rasters for purposes of additive color photography in that several layers of film mass of different colors pressed together to form a block and from this block by peeling or planing perpendicular to the plane of the layers one Film foil is removed. This procedure can be repeated by doing the first Layers removed from the block on top of one another and then proceed in the same way. To this In this way, multi-color dot grids are created.

Negative material for additive color photography using multi-color line grids produced in this way or a grid of points consists, for example, of a celluloid carrier or other transparent ones Carriers with applied raster film and photo emulsion applied to it. The exposure happens thereby through the celluloid carrier. But you can also use a celluloid carrier initially a photo emulsion and place the color grid on top of it.

The positive material for the additive color photography process described also mostly exists from a celluloid carrier or paper carrier, applied photo emulsion with applied Color line grid or from a carrier with an applied color line grid and applied to it Photo emulsion.

When recording, copying, and projecting using the above In the case of photographic material, there is a loss of intensity due to reflection on the celluloid or other Carrier and / or color raster, which is disadvantageous, and the luminosity and brilliance of the color images

It is also possible to "apply" a compensation rate by dipping. A tried and tested "method" for tempering consists in blowing a gaseous compound which can be decomposed into hydrate oxide with water in the presence of water vapor from a nozzle to form thin, transparent, resistant layers onto the surface to be tempered. This method is also suitable for the production of photographic material according to the invention with follow to apply. . . . . ^:; The advantages achieved by the invention are in the reduction of reflectivity. to film material for additive color photography see, whereby it is achieved that a greater light intensity to blacken the photo-sensitive Emulsion reaches the photo material in a less bright; ^ camera use can find- 'ayfcli' dief.Reprodu-tion improved - q; will.
