To aZZ whomit may concern:
a citizen of theUnited States, and a residentof the borough of Manhattan, city, county, and State of New York, have invented certain new andusetul Improvements in Photographically-Sensitized llIediums, of which the following is a Specification.
This invention relates to a sensitized pa per commonly known as Japanese tissue for use in the art of photography, and to the method .ofmaking the same.
One of the, objects oi the invention is to produce a paper of the character above specified which may be used either as a negative or positive upon which the photographic pictures are displayed.
Another object is to produce an integral non-separable photographic paper or film.
Other objects will appear from tlIG hB I'B inafter description and claims.
I have produced a new and veryusetul photographic film, sensitized with rapid printing silver emulsions consisting of silver bromid, bromo-iodid, chloro-bromid and chlorid to be used either for negatives r for positives, and also for contact printing and enlarging by either natural or artificial light.
This new productis based upon the discovery that the light sensitive emulsion may by absorption, be embodied in the base or support in one integral non-separable body.
By this, I mean that the support or base and light sensitive emulsion'forms one integral whole as contradistinguished to those products in whichthe emulsion and the supobtained thereby and the product thus produced, will now be described. p
take a piece of Japanese tissue and spread thereupon with a brushthe' warm,
light sensitive emulsion and permitthe emulsion to be absorbed into and through the fibers of the tissue, thereby causing the light sensitive emulsion andthe tissue to form one Specification of 'Letters' Patent.

tion, as distinguished from the usual math-- ods of first sizing and then sensitizing the paper.
' Any superfluous emulsion on the-surface of the tissue is removed by means of another brush and then the sensitized tissue is hung gelatin until it becomes dry.
The sensitizing must be done in a dark room by ruby or other non-acti-nic light.
The Japanese tissues being very thin, ab sorb only a sufiicient quantity of the emul-- sion to produce a brilliant image. As the emulsion is practicallyron'botli sides of the Japanese tissue film, it can be exposed or printed on either side.
By the use of my invention, no'blisters are formed, neither does it trill or separate from the support during the manipulations of developing, fixing and washing the print The print dries quickly be tween blotters under mild pressure and re mains flat and .fieXible and cannot break. It retains the rich, silky surface characteristic of the Japanese tissues and a print or enlargement produced on the Japanese tissue film has, an extremely beautiful'appearance and pleasingelfect'and'in appearance is greatly unlike .an ordinary photograph, as it has a marked resemblance to anetching. By reason of the fibers of the tissue, an
advantage accrues by difiusion of thecoarse, retouching on portrait" negatlves, thereby .i-ag g I sa\-in'gthe time of the artist. The negative or print is durable and permanent as the fibers of the tissue protect the minute silver particles of which the image consists, from deterioration from atmospheric action or otherwise. The emulsion may be applied witha brush as stated or by floating the tissueon the surface of the emulsion or the consisting of a support of Japanese tissue,
said support being impregnated with a rapid printing silver emulsion which is distributed upon both sides thereof to form an integral non-separable whole.
In witness whereof I have hereunto set my 15 hand at the borough of Manhattan, city and State of New York, this fourth day of Deeember, 1915.
