PHOTOGRAPHIC TRANSFER.
Application led February 14, 1924. Serial No. 692,885.
ferred, will produce a pic-ture with an at-V tractive and sparkling or metallic effect.
The invention consists in the several novel features hereinafter set forth and more particularly defined by the claim at the conclusion hereof.
ln the drawings: Fig. l is a diagrammatic sectional view on an enlarged yscale of a printed strip of carbon tissue applied to a glass plate. Fig. 2 is a View similar to Fig. l, showing the carbon tissue strip with the backing removed. Fig. 3, is a. diagramniatic sectional view on an enlarged scale of the finished transfer.
ln the practice of the improved method of producing photographic transfers, a sensitized strip or roll 1l, generally known as carbon tissue, and which consists of a coat ing or film 4 of transferable pigment containing colors sensitized with potassium bichromate and spread on and adhering to a backing of paper All) is first printed from the desired negative by exposing` it to light in the usual manner. The print is then dipped in cold water and applied with its film side against the bach of a glass plate 5 or upon the face of a metal plate and is squeegeed onto the plate. Next, itis dried for about 15 minutes under a slight pressure. Next, the print is developed by inm'iersion of the plate with the print thereon in warm water, ranging from 95" to lill@ Fahr. This develophas been released by dissolving it in warm water. The paper backing comes off the` plate during this developii'icnt. Next, the
plate with the developed film thereon isV ing is continued until the surface pigment ferred film and gives the picture a sparkling or polished and metallic effect. lVhen the transfer is made onto metal, the metal is given a polish or suitable finish which will give a metallic appearance or sparkling effect to the light spots in the transfer'. When the transfer is made on a glass or a transparent plate, it is given a protective coating of shellac and provided with a backing of cardboard to prevent the transfer from being marred or mutilated.
"` rlhe transfer, when made'in accordance with the foregoing method, has an attractive and sparkling metallic effect according to the character of the bronze used, result-ing from the bronze on the glass plate or the` polished face of the metal 'plate itself when non-transparent plate is used, appearing. through the light portions of the transfer.`
1 ie invention is not to be understood as `restricted to the details set forth, since these may be modified within the scope of the appended claim, without departing from the spirit and scope of the invention.
Having thus described the invention, what we claim as new and desire to secure by Letters Patent, is:
That improvement in making photographic transfers which consists in first dipping a strip of undeveloped printed carbon tissue in cold water, then pressing the ilm side of the wetted strip against one face of a rigid transparent plate, then drying` the strip, then developing the film while the strip is on the plate and removing the backing of the strip during development, then drying the developed lihn, then applying a bronze coating to the bach sideof the developed film which will appear through the plate and the light spots of the film to form a background, and then applying a protective covering to the bronze coating.
Signed at Chicago, Illinois, this 7 th day of February, 1924.
