Patented Jan. 6, 11925,,
CHARLES N. WATERHOUSE, OF OKLAHOMA CITY, OKLAHOMA.
COMPOSITION OF I/IATTER FOR TREATING PHOTOGRAPHIO PAPER.
NO Drawing.
To a7Z whom it may concern:
Be it known that I, CHARLES N. VVATER- HOUSE, a citizen of the United States of America, and resident of Oklahoma City,
5 in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Composition of Matter for Treating Photographic Paper, of which the following is a specification.
The object of my invention is the production of a composition to be applied to photographic paper for preventing breaking or creasing of the film surface thereof after the picture is made on the photographic 15 paper, rendering the same soft and pliable.
My composition consists of a mixture of glycerine, alcohol, formaldehyde and table salt.
In preparing the composition, I prefer to use the ingredients in about the following proportions, viz: glycerine 8 parts; alcohol 1 part; formaldehyde 1 part; and table salt 1 part.
These ingredients, when mixed, form a liquid of such consistency as to enable it to be applied to the surface of the photographic paper to be protected, and I have found in practice that the following method has proven eflicient and satisfactory, and the in- -;o vention is especially useful in protecting the surface of pictures known as circuit or panorama pictures that measure from six to sixteen inches wide to ten feet or more in length. 7
a; The first step of the process is to print, develop, fix and wash the picture in the ordinary manner, after which the surplus water is removed from both sides of the print. The print is then placed face down it) upon a squilgee board and the chemical composition, which has been thoroughly mixed, is applied with a soft sponge or lint cotton to the back of the print, impregnat- Application filed January 15, 1924.

ing the surface of the print until. the image is finally discernible through the back of the print. The print is then dried in the usual way, i. e., by laying it out flat, or by suspending it from a hanger, as may he preferred.
After the print has been treated in the manner stated, the paper and film surface are so soft that the picture may be folded without liability of cracking or injuring the film surface, the advantages of which will be apparent to those skilled in the art.
It will be understood that glycerine is the fundamental content of the formula, its use resulting in softening the paper, and if used in the proportion given, it will not separate the film from the paper.
The alcohol used in the composition has three functions, viz: first, it thins the glycerine; second, it opens the pores of the paper so that the glycerine may penetrate the same; and third, it acts as a drier, leaving the other solutions in the paper. The formaldehyde is added as a hardener, and when used in the proportions and with the other ingredients given, has a rubberizing effect on the paper which prevents its cracking in folding. The salt is used as a flattener, preventing the paper from curling.
I claim:
1. A liquid composition adapted to soften the film surface of photographic prints after the picture is made, fixed and washed, for the purpose of rendering the same pliable, comprising glycerine; alcohol; formaldehyde; and table salt, thoroughly mixed and commingled.
2. A liquid composition for use in the treatment of photographic prints consisting of: 8 parts glycerine; 1 part alcohol; 1 part formaldehyde; and 1 part table salt.
