7 Claims.

This invention pertains to an identification ticket, and more particularly to the paper stock therefor, including the method of producing the same. Such tickets are commonly used for admissions, receipts and as legalized mutual race betting tickets.

The object of the invention is to produce a ticket or paper stock therefor of a character which may be readily identified for the purpose of detecting counterfeits and preventing erasures and the changing of values or identifying marks printed thereon.

Another feature of the invention is to produce a paper stock from which the ticket is out which may be printed in an automatic machine as it is delivered oped from the interior of the paper stock as distinguished from surface printing by ink.

The use of a coloring dye in the production of paper having reactive well known in the art and has been applied to so-called safety paper, as outlined in an article appearing on page 61 of the September 6, 1928, issue of the Paper Trade Journal, a publication of New York, New York.

It is the purpose of this invention to utilize such coloring dye in a manner'to provide a paper stock from which such tickets may be produced to largely overcome, or greatly minimize, the problem of identification and alteration.

In the use of identification tickets, particularly mutual tickets at race tracks, substantial losses are encountered through counterfeiting of pay tickets or the alteration of non-pay tickets to pay tickets by application of eradicating fluids, scratching and the like. Many attempts have been made to produce a paper stock to avoid or changing identification marks such as will indicate to the pay teller that a ticket presented is counterfeit or has been altered.

The invention herein set forth not only provides a ready means of identifying the paper stock to distinguish the ticket from those of c0un terfeit stock but, so far as is known, eliminates any possibility of altering the printed matter. This is in a dye, either neutral or of any color, will chemically react through a surface coloring upon the application of a suitable agent, and wherein the surface coloring is applied thereover in such manner as not to resist erasures.

chemical characteristics is The full nature of the invention will be understood from the accompanying drawing, the following description and claims:

Fig. l is a perspective View of a section of stock in the form of a strip greatly exaggerated as to thickness and with successive layers peeled oil to same ticket after having been identified and accepted for redemption through application of a stamp. Fig. 6 is a modified form of Fig. 5 showing another method of identification for acceptance and redemption through a fingermark.

The paper stock as illustrated in Fig. 1 is developed in the usual manner on a paper making machine, preferably of three layers of two or more colors. As illustrated herein, and for example, the outer layers are colored yellow and the inner layer is colored red. Obviously other colors may be employed. Thus, as in the usual practice in producing ticket stock, a red coloring dye may-be applied to the stock carried over the carried over the rolls on In this instance, the yellow dye, or any other desirable color, is of a character which is reactive to an alkaline solution to change its color, the paper fibres of the outer layer being impregnated therewith. A satisfactory dye for this puras No. 364 and the form in which this is marketed is believed to be the disodium salt as follows:

S OsNa Upon treatment with to red is believed to example, will probably gens with sodium.

This dye is reactive to an alkaline solution of printing type. Such color of the reactive dye such through the surface deemed a stamp 'may serve three functions.

a pH greater than 16, in that upon such solution being applied, the color of the dye will be changed thereby. For example, the above described dye will so react as to become a reddish pink color;

After the stock is thus developed and built up with the impregnated dyes, it is sized and passed through coloring rolls for applying a difierent surface coloring to the dye impregnated outer layers. Such surface coloring may be green, blue, or any other suitable color as shown in Fig. 2. Before applying portant that the stock be sufficiently sized to prevent any material penetration thereof. This results in the surface coloring being destroyed upon the lightest application of erasure or scratching. Such surface coloring is preferably selected so as to react by a change in color upon application of any of the known ink eradicating solutions.

The stock when thus prepared is ready for trimming, printing and rolling into suitable rolls for use in ticket vending or totalizing machines, or cutting to ticket size, printing and vending in the usual manner.

Fig. 3 shows a section of a strip of stock wound in a roll after being partially printed for use in an automatic ticket printing and vending machine.

Fig. illustrates the final printed and cut ticket with the identifying indicia thereon. This indicia, as shown in Fig. 4, may be applied by the application of surface ink in the usual manner of printing. But, preferably, and to prevent erasures, and alterations of the identifying indicia the printing may be effected by the mere application of an alkaline solution upon the type application of the aleffect of changing the that it will show coloring and in this case develop a printed identifying indicia comprising the discolored and impregnated dye, as distinguished from mere surface printing. The result is that such identifying indicia cannot'be removed by erasure from the surface of the ticket for alteration thereof as is the case with surface applied ink.

A ticket of this character further has the major'advantage of convenient identification for ackaline solution has the ceptance and redemption.

' As shown in Fig. 5, upon the ticket being reillustrated therein as embodying the word Paid may be applied with the alkaline solution thereon obtained from first applying the stamp to the usual so-called ink pad which is impregnated with the solution instead of ink. Upon thus applying the stamp the change in color through the chemical reaction of the dye as above referred to will promptly appear. This will be evidence that the ticket to be redeemed is not a counterfeit.

As suggested in Fig. 6, the redeemer of the ticket need not use a stamp but may moisten his fingers with the alkaline solution conveniently arranged in a sponge so that when he grasps the corner of the ticket for redemption, the ticket will change color and show his fingerprint. This is illustrated in the lower left-hand corner of the ticket illustrated in Fig. 6.

Summarizing the advantages and uses of identification tickets and paper stock therefor made in accordance with this method, the chemical reacting dye with which the outer layers of the stock are impregnated, and the surface coloring The ticket may be the surface coloring, it is im-' readily identified from a counterfeit ticket by the application of the alkaline solution in any convenient manner (Figs. 5 and 6) to effect a chemical change in color. Secondly, the surface coloring will be removed by mechanical erasure, and will chemically react to the known ink eradicator solutions to the end that any attempt to alter the indicia by mechanical erasure or the use of a solution for eradicating the identifying indicia to permit alteration thereof, will immediately show up through non-removable discoloration. Thirdly, it enables the use of a printing liquid containing an alkaline solution, as distinguished from the conventional oil base inks,

for use in automatic ticket printing and vending machines. Such alkaline ink, in effect develops its coloring from the die impregnated stock, forestalling any attempt at surface erasure.

Said advantages mentioned will make it difficult, if not impossible, to either substitute a counterfeit ticket or effect alterations in the legitimate ticket.

The invent-ion claimed is 1. An identifying ticket including paper stock impregnated with a coloring dye chemically reactive to a color changing agent and a superficial surface coloring applied over the exposed surface of the dye impregnated stock without penetration, said superficial surface coloring being of a different color than the impregnated coloring dye and through which a color changing effect may appear upon application thereto of a color changing agent through the medium of its reaction to said impregnated coloring dye.

2. An identifying ticket including a paper stock impregnated with a coloring dye chemically reactive to a color changing agent, and a superficial surface coloring dye of a different color than that of the impregnated dye extending over the effective surface of the stock, said surface coloring dye being reactive to an ink eradicating agent and the surface of the stock covered thereby being sufficiently sized to prevent undue penetration by said surface coloring through which said color changing agent may react on the impregnated dye.
