TRANSFER SHEET.

Application filed December 11, 1925. Serial No. 74,771.

This invention relates to a process for making transfer sheets and an' ink for use in the process.

Heretofore transfer sheets have been made by a process which included an ink which by reason of its character had to be kept quite a little above the ordinar temperature in order to work properly. ith such an ink and with the usual processes a comparatively small number of transfer sheets may be formed per hour, consequently they are com aratively costl eretofore the dlfiiculties of the process wherein the ink must be warmed have been sought to be overcome, but in so doing resort has been had to such coloring matters as aniline dyes, which. when transferred on to such material as silk become indelible and cannot be washed out.

Applicant has as an object a process and an ink therefor by which transfer sheets may be printed cold and the transfer made on to the material is fugitive, when washed as in ordinary practice. I

In describing the invention in detail and a particular product made by the use of the process, reference is had to the accompanymg drawing, wherein I have illustrated a particular product and wherein like characters of reference designate corresponding parts throughoutthe several views, and in which:

Figure 1, illustrates a transfer sheet with a design in the plurality of colors thereon; Fig. 2, illustrates a transfer sheet with a design in one color thereon.

In order to car out the process applicant has devised a printing composition, called an ink.

The ink used by applicant is made preferably in the following manner.

Ordinary rosin of commerce is heated in any suitable or appropriate way until it .will flow freely. n a separate rece tacle mineral parafiine, the ordinary para e of commerce, is heated, until it will flow freely. The two, rosin and parafiine, are then mixed, pouring one into the other, with constant stirring. In addition to the rosin and parafline, cocoa butter and mutton tallow are melted together in a receptacle until they will flow freely and are then mixed with the mixed rosin and paraifine by pouring therein with constant stirring.

The mixture resulting from the above described operations is then ground either by hand or in some such device as a suitable type of power paint mill and to it is added preferably as the grinding proceeds, such guantity of coloring matter as will give the esired color and shade to the transfer design then impressed to the desired material. a The coloring matter used by applicant is a most important element of the invention. Applicant has found that for his purposes a mineral coloring matter is most appropriate, because the composition of his ink is such that although the ordinary handling of his transfer sheets when dry will not smudge the design, nevertheless, a vi orous washing of the material to which the esign .is transferred will remove. the ink from the material. Applicant has found that if a mineral coloring matter, that is, one which does not combine with the material, to in effect d e it, is used it being merely held mechanically by the mk on the material, it is also removed, by washing, so that it is fu 'tive.

fter properly grindin the mixture, I adjust the viscosity so t at it will work properly with the particular type of ress and ink rollers used. I .do this by a ding rosin made fluid by heat until by trial I reach the exact viscosity desired.

The quantities used in making my ink are about as follows Mutton tallow, 1 oz.; cocoa butter, 1 oz.; parafine,-4 oz-; rosin, 6 oz.; additional rosin, a suflicient quantity; mineral pigment, a sufficient quantity.

Any desired mmeral pigment may be used that will give the desired color.

If what is technically known as offsettin occurs the quantity of rosin may be slig tly increased, and in general the vis-' cosity of the ink will be regulated by the type of roller present on the press upon which the ink is used.

The ink made as hereinbefore described is usable upon ordinary plate presses. The ink bein used to fill the usual font and theprintmg of the transfer sheets being accomplished as ordinary printing. I

In Fig. 1 I have illustrated a five'pointed star on a sheet 1. The points 2 and 3 of the star are colored respectively, yellow and blue. In Fig. 2, I have illustrated a five pointed star in outline on sheet 4 the bounding lines all being in one color, preferably blue. For the yellow I preferably use chrome yellow and for blue, ultramarine.

drying, in reverse on the material to which the design is to he applied and a hot roller for that reason are used in the composition.

or sad} iron is applied thereto, whereupon the design Will be transferred to the material reproducing the color or colors on the transfer sheet.

Cocoa butter and mutton tallow have properties not possessed by rosin and paraf fine in that they stay moist much longer and This property of the cocoa butter and mutton tallow causes the transfer design to loosen up more readily during the transfer and gives quicker fluidity. These properties could not be obtained by the useiof rosin and parafiine.

Although I have particularly described my process and products resulting from my process, nevertheless, I desire to have it In use the transfer sheet is applied, after'f'understood that the forms selected are merely illustrative but do hot exhaust the possible expresions of the idea of means underlying my invention.

What I claim as new and desire to secure -hy Letters of Patent of the United States:

1. An ink for printing transfer sheetsconsisting'of, cocoa butter, mutton tallow, parafline, rosin and a mineral pigment proportioned to give a printing viscosity at ordinary temperature.

2. An ink for printing transfer sheets consisting of and in proportions as follows, cocoa butter one ounce, mutton tallow one ounce, parafiine four ounces, rosin six ounces, mineral pigment, a suflicient quantity, together with suflicient additional rosin as to give printing viscosity at ordinary temperature.
