ABSTRACT:

FIELD OF THE INVENTION
This invention relates to secure documents, that is, documents that receive so called variable information at one or more locations thereon, which information is protected against alteration.
BACKGROUND OF THE INVENTION
There has long been a need for secure documents, that is, documents that cannot be readily copied or counterfeited, or readily altered. As modern technology has progressed, the technology employed by counterfeiters or those who would alter documents for illicit purposes has likewise improved. And, of course, modern society employs a variety of documents for a variety of purposes which can be misused if they can be readily altered, copied or counterfeited.
Of immediate concern as far as the present invention is concerned, is providing a document that is secure against alteration. For example, various forms of documents providing for personal identification such as drivers licenses have been altered, frequently, for the purpose of falsely indicating the birth date of the license holder. Various documents of value, including specifically checks, have been altered to change the stated value of the check.
Other cases where documents may be altered include those where one wishes to alter the date of a document or even alter the signature placed on a document. In each of these cases, it is typically the so-called variable information that is altered.
As is well known, many documents include so-called fixed information which is information that will not change from one document of the same character to the next. For example, the basic format of a common check is fixed information except for that designating the check number. When the check is completed, variable information, including information in the form of the identity of the payee, the signature of the pay or and the amount of the payment as well as the date of the payment is added. This information is termed variable information because it will typically vary from one document to the next, even in the case of the pay or signature as many accounts have more than one signatory who can complete a check.
Quite clearly, it is highly desirable to prevent alteration of such documents so as to prevent misuse of the document. The present invention is directed to accomplishing that goal.
SUMMARY OF THE INVENTION
It is the principal object of the invention to provide a new and improved secure document. More specifically, it is an object of the invention to provide a secure document that cannot be readily altered.
An exemplary embodiment of the invention achieves the foregoing object in a secure document that includes a substrate ply for defining the body of a document. Indicia are provided on the substrate to designate an area to receive variable information by an impression and who's alteration is to be avoided. A chemical carbonless imaging system is located on the substrate at the area and is operative to form a visible image upon receipt of an impression and a transparent film is located on the substrate to cover the area.
In a preferred embodiment, the substrate is paper.
In a preferred embodiment, the chemical carbonless material is operative upon receipt of pressure by a writing or printing instrument to form a visible character or characters at the point or points of application of the pressure.
In a highly preferred embodiment, the film is a coating. Even more preferably, the coating at least partially penetrates the substrate and/or bonds to the surface of the substrate like conventional paints.
In a highly preferred embodiment, the coating is an ink receptive coating.
Most preferably, the coating is an ultraviolet light cured coating.
The invention also contemplates a multiple ply secure document and such includes a record ply substantially abutting the substrate ply along with image transfer material at the interface of the plies so that an impression formed on one of the plies will be transferred to the other.
Other objects and advantages will become apparent from the following specification taken in connection with the accompanying drawings.
