Abstract

The document security device is intended primarily for the customs service and enables the authenticity of entries and stamp impressions in customs and other documents to be ensured, with the possibility of immediate control by irradiating the entry or stamp impression with ultraviolet light, thereby preventing their modification, addition and removal. It consists of 0.5 to 2.0 weight percent of a compound of structural formula 0 and further of 98.0 to 99.5 weight percent of ink or stamp ink.

Description

The invention relates to a securing documentation device.

The device is intended for the customs service and enables the control of the authenticity of entries and other markings, such as stamps in customs or other documents as required.

Until now, entries in customs documents are made with ballpoint pens and these documents are stamped using a modified stamp ink. The ballpoint pen paste and stamp ink are currently secured with a substance for which activation is required, ie development with ammonia vapor before checking the registration or a stamp under an ultraviolet lamp. Due to the health hazards of ammonia and other problems, this method of securing is not entirely suitable for document checks on a larger scale. Frequent manipulations with entries and stamps in customs documents are thus very difficult to detect and in many cases not at all, for example due to the current lack of ammonia at the time of the need for inspection or lack of time at check-in.

The above-mentioned drawbacks are eliminated by the securing documentation according to the invention, the essence of which consists in that it consists of 0.5 to 2.0 weight percent of a compound of structural formula.

and 98.0 to 99.5 weight percent ink or stamp ink. The advantage of the securing documentation means is its ability to fluoresce under illumination of a pen or stamp under ultraviolet light of a wavelength of 350 to 360 nm, without the need for prior development, as is the case with existing and used means.

This feature is advantageously reflected in customs documents, such as customs declarations for foreigners, workbooks of foreign workers, truck documents, etc. Easily and quickly after irradiation with an ultraviolet lamp, you can identify the authenticity and completeness of the registration or stamp or the place where it was originally entry or stamp imprint removed. As far as the injured stamp imprint is concerned, the place where the stamp was originally imprinted can be safely identified using this means, even after a long time. This is not possible with the protection method used so far.

The benefits will be in the possibility of preventing the export of duty-free or non-exportable goods, ensuring the authenticity or one-off use of documents for which the relevant fees must be paid, even in vertical currencies, eg transit permits for lorries . All this has considerable economic significance and benefit.

The invention is further elucidated on the following examples of a specific embodiment, verified by practical tests.

Example 1

The securing documentation was made of 98.0 weight percent ink and 2.0 weight percent compound of structural formula

and the mixture was mixed thoroughly.

With the help of filling the records on the customs declarations of foreigners at the same border crossing, their pens were checked on arrival at the Czechoslovak Socialist Republic. On the return, after irradiation of the entire record with 360 nm ultraviolet light, adjustments and additions to the records of the amount of the imported currency were found - these adjustments did not fluoresce the original records. '

Example 2

The securing documentation was made of 98.0 weight percent stamp ink and 2.0 weight percent of the same compound used in Example 1, and the mixture was again mixed thoroughly.

Documents issued for payment in foreign convertible currency for a one-time passage of the truck through the territory of the Czechoslovak Socialist Republic were marked with the stamp imprint of the stamp. It is known among truck drivers that the stamp color, including the original securing means, can be removed with egg white and the document thus completely unmarked, i.e. without a stamp, can be reused during the next passage through the Czechoslovak Socialist Republic. This also happened in the case of the document being checked. After its inspection, after irradiation with ultraviolet light of a wavelength of 360 nm, the place of the original imprint of the stamp was found and the truck driver was proved to be able to use the modified document repeatedly.

This securing documentation, either as ink or as a stamp ink, can be used in many fields of human activity, wherever it is necessary to ensure the authenticity of the entry or stamp and thus, for example, to prevent modifications, additions or re-use. issued documents, and thus sometimes significant economic losses or other negative consequences. However, the securing documentation can also be applied by brushing, spreading, etc.
