COMPOSITION FOR PRINTING INKS FOR TRANSFERS.

No Drawing.

To all whom it my camera:

' Be it known that We, Tnownmoen MAI/{S- TON and IRA F. B. HUTTON, citizens of the United States, residing. at Morristown, in the county of Morris and State of New Jersey, and at Woodhaven, in the county of Queens and .State of New York,

respectively, have invented certain new and useful Improvements in Compositions for Printing Inks for Transfers, 'of which the following is a specification.

Our invention relates to a new and improved composition for printinginks -.for transfers.

For many years transfers havingan ink which is solid at ordinarytemperatures have been used for impressing designs upon fabrics and articles made of leather or fabric.

- until it became liquid and thenprint therewith upon a sheet of pa er by means of a die having the desired gure, word or the like engraved therein. The ink quickly solidified upon the paper producing a reverse impression of the design, word or the like intended to be transferred and when this transfer was laid upon the article upon which it was intended to make the impression, and heat and pressure were applied as for example by means of a. hot iron, the solidified ink again melted and was transferred to the article.

Up to the present time a number of serious defects have existed in such inks. has not been possible hitherto to produce an ink which was flexible and which wouldadhere to the article with sufli ient tenacity so that if the said article was bent or 40 sired impression would be lost. For example, it has been very common to impress trade marks by the ink and method before mentioned, upon hosiery and similar articles of. wearing apparel which are rum led and bent when used and the flaking o the ink has been particularly objectionable in this connection.

It has been customary to heat the ink crumpled, the ink' would flake and the de-' embroidered is as follows Application filed August 27, 1921. Serial No. 495,953.

It has hitherto not been possible to produce an ink which could be scraped off satisfactor ly from the said die, so that onl the engraved part of the said die carrie the ink. As a result thereof, some of the ink was impressed upon the leather, fabric or other article at al point where it was not desired. This result was; called bleeding and it was particularly objectionable especially in making impressions upon white fabrics for embroiderin'g purposes.

It has also been hitherto ot possible to producegold and silver colored transfers which would have the desired brilliancy and s'harpnessof definition.

The objects of our invention are chiefly to produce a. flexible ink which will adhere 55 with great tenacity both to the paper and to the article upon which the 1m ression is finally made and which will be perfectly flexible.

Another object of our invention is to roduce an ink having these desirable 0 aracteristics, which will be hard even in the summer time, so that it can be readily handled, as a sticky ink is objectionable.

Another object of-our invention is to produce an ink whereby the phenomenon of bleeding can be obviated and which will produce a brilliant impression when a gold or silver color is employed.

Other objects of our invention will be set forth in the following description which i1- lustrates preferred examples thereof.

We have given two examples of our invention, one intended to be used for impressing designs to be 1 embroidered upon" fabrics and the other to be intended for im pressing trademarks and the like upon colored fabrics.

. An example for producing designs to be The ingredients used are preferably eleven pounds of rosin or colophony, five pounds of beeswax, four pounds of ultramarine blue or seven. pounds of chrome yellow, depending upon the color desired; eight ounces of Venice terpentine which is preferably a true Venice turpentine; twelve ounces of lithographic varnish No. 8, which is a technical term for boiled linseed oilwhich hasbeen boiled to a certain consistency; one pound of gum elemi.

The rosin causes the ink to be sticky so that it will adhere to the object.

The beeswax is employed because when heated, it penetrates the fabric and carries along the color with it into the pores there-- of. i The turpentine is used because of its adhesive or sticky qualities andbecause 1t imparts an elastic, rubber-like quality to the.

ink. This is because the said turpentine dries very, very slowly, so that when the ink has been used for making the impression upon the article, the rosin causes a surface drying in a comparatively short time, but the body of the ink remains soft for a very long time so that'the-bodi of the ink can readily bend andwill notfla e off. The boiled linseed oil or lithographic varnish has a -combined action with the beeswax of causing the'ink to be readily released from the paper and it also enables the die to be wiped clean by means of a sharp blade'as' is, well known, so that there will be no .bleeding. The gum elemi assists in impartingv a certain elasticity to the ink and it cooperates.

in this with the turpentine. However, the

gum elemi can be omitted. if enough turpentine is used.

'of' the amount of one ingredient may be There may be considerable variation inf the above proportions and in the ingredients which may be substituted forthose before mentioned, and -as we believe that this is a pioneer invention, we desire to carefully state the most important of thesevariations.

For example, from nine to fifteen pounds of rosin may be substituted for the amountabove given. From one to seven pounds; of beeswax can be substituted for the amount before given, but if the amount of beeswax is diminished, then the proportion of boiled linseed oil or lithographic varnish must be'inoreased. For example, if only one poundof beeswax is used then aboutthirty ounces of the said lithographic varnish should be used, and if seven pounds of bees-- wax is used then only fourounces of the-said varnish are necessary. From three to seven pounds of ultramarine blue/and from three to ten pounds of chrome yellowmay be employed for the above purpose, depending upon the intensity of the'shade employed.

' rom four to twelve ounces of the turpentine may be used and from one-quarter of a pound to three pounds 'of' the gum elemi may be employed, but since the rosin, the turpentine and the gum elemi cooperate in making the ink adhesive, a diminution counterbalanced by the increase in the amount of the other equivalent substance or substances.

beeswax; one and one-half teasers In preparing impressions of trade marks or the like for black or other colored fabrics, the following ingredients and propor tions have been found efficient:

.' Sixteen pounds of rosin; one pound of ounds of turpentine, preferably the trueenice turpentine, and" it may be noted at this point that a so-ca'lled imitation Venice turpentine made of a mixture of domestic turpentine and rosin, may be substituted for the true Venice turpentine; three and one-half pounds of the said lithographic varnish No. '8, It

is to be understood that we do not limit ourselves'to the No. 8 lithographic varnish as other grades may be employed without, however, giving as good a result as the No.8.

The amount of rosin can be varied from ten to twenty pounds. The amount of beeswax can be varied from four ou'nces to ten pounds. The amount of turpentine can be varied from one ounce to three pounds,'

and the amount of-lithographic varnish can be varied from one pound to six'pounds, it being understood as before mentioned, that etable black, ivory black and drop black chrome green in the various shades thereof; red in the vermillion and scarlet shades; purple and brown. I

Besides the above mentioned colors which are pigments, the aniline colors in various. shades may be employed, and other colors,

. e5"- eflects for trade mark transfers the lake colors, may be employed by combining the aniline colors with lithopone,

pure oxide of zinc, pure stearate of zinc,

whiting and lead whites.

If aniline colors are not employed, the

ink is prepared by melting the rosin and beeswax together by placing them in a vessel which is heated, and stirring them to- 'gether. The turpentine and lithographic varnish are then'added and stirred; It is preferable not to heat the said ingredients or ink above 200 Fahix, either-in the manufacture of the ink or in the application thereof in the transfer. This temperature "limit is desirable because otherwise the propertles of the rosin and beeswax are 1n ured.

After the said ingredients have been llllil thoroughly intermixed, then the colors are slowly added and mixed therewith.

If aniline colors are employed, it is preferable to first melt the beeswax in a separate vessel and then add these colors slowly with constant mixing. v

The rosin, has been melted-in a separate vessel and the melted mixture of beeswax and aniline colors "are hen added very sl owvly and with careful and continuous mlxing.

If it is desired to utilize the colors which we have called lake colors, then'after the aniline dyes have been handled in the manner before mentioned, the lithopone or the other substances mentioned 4 in connection therewith are slowly added to the melted ink in owdered form.

Of t e in edients before mentioned inconnection w th the manufacture of the lake.

colors, we prefer to use oxideof zinc. This I is because the oxide of zinc has acertain be treated in the manner well known in the arts and in order to make them of the same consistency and softness as the said colophony. For example, the rubber would be treated with ether and would beused form of varnish No. 8, the following subin small quantities. 7

Instead 'of the beeswax, the following waxes may be substituted:

Carnauba wax, ceresin, Japan wax, Montan wax, ozokerite, parafline residues and marble wax.

Instead of the boiled up raw linseed oil before mentioned, preferably used in the stances may be used, suitably boiled or otherwise treated so as to make them'sufficlently consistent:

Castor oil, China nut oil, cocoa fat, cocoanut oil, corn oil, cottonseed oil, fish oils, animal oils such as lard, seal, tallow, whale, oleo, and the like, and parafiine oil, and various other vegetable oils such as wood oil, peanut oil, pine oil, rapeseed oil, red oil, rosin oil, sesame oil, soyabean oil, tar oil and the like. V

Copal varnish could be used instead of the Venice turpentine.

We have endeavored to carefully state the various ingredients which'may be used-for our purposes and the various preparations of some of them which will give good results, but we wish to make it clear that these are only stated as preferred ingredients and proportions and we are not limited thereto, as-

changes and omissions can be made without departing from the spirit and scope of our invention.

Since the ink is not sticky when in the solid state, it inakes no difference if a certain amount thereof is allowed to solidify in the machine when for example, the operation of the machine is stopped at the end of the Working day, because the ink melts without sticking to the die when it is again heated,

so that all bleeding is obviated.
