BYRON B. GOLDSMITH, OF NEW YORK, N. Y.
CARBON-PAPER AND PROCESS FOR MAKING SAME.
No Drawing.
To all whom it may concern:
Be it known that I, BYRON B. GOLD- SMITH, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and. useful Improvements in Carbon-Paper and Processes for Making Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to an improved form of duplicating sheets, commonly called carbon paper, and, to the process of making the same.
The principal advantages of my invention are the following. The paper used may be lighter and a lower degree of uniformity in texture is required than has been the case hitherto. The final sheet is perfectly uniform and is stronger than hitherto possible, and the peeling off of the pigment layer from the sheet is entirely prevented. At the same time a thinner and less expensive layer of pigment-bearing coating can be employed with success. The pigmentbearing coating may be applied to one or both sides of the paper..
In making carbon paper by my process, I first produce a waxed fabric by treating the sheet to be coated with any waxy or greasy material. The sheet may be either thoroughly impregnated or may be coated on one side, or on both sides. After the paper has been thus prepared, the pigmentbearing composition is applied in a manner well understood in this art. Any suitable composition capable of strong adherence to the waxed paper foundation may be used, and, of course, any color desired may be Specification of Letters Patent.
Patented July 4., 1916.
Application filed August 9, 1915. Serial No. 44,452.
employed. This final layer may be applied either to one or both sides of the paper.
The difficulties experienced in making carbon paper are, first, it is necessary to get as thin a paper as possible, and have it as uniform in thickness as possible. The thinnest papers that have been used for making carbon paper have been imported, as the domestic product was not sufliciently uniform. By my process I can take a weak thin domestic tissue paper, and by the treatment, make it more uniform as Well as stronger. The second difliculty has been that very frequently the coating peeled in use. By my process a perfect adhesion is effected, and the coat cannot peel.
It is to be understood that While Wax is preferred, this word as used in my claims is intended to cover such substitutes and equivalents as have the requisite properties.
What I claim is- 1. The process of manufacturing duplicating paper which consists in applying a suitable pigment-bearing layer to a foundation sheet of wax laden paper, substantially as described.
2. The process of manufacturing duplicating paper which consists in first applying to a sheet of paper a foundation of wax and then laying over this a film of a suitablepigment-bearing compound, substantially as described.
3. As an article of manufacture, a sheet of paper having a foundation layer of wax interpenetrating its texture and an external pigment-bearing layer united with said foundation layer, substantially as described.
In testimony whereof, I aflix my signature.
BYRON B. GOLD SMITH.
