DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/GB91/01697 filed Oct. 2, 1991.
The present invention concerns improvements in or relating to the security of articles, goods, vehicles or premises. More particularly, the present invention provides a composition and method for the prevention of those acts listed hereunder utilising a combination of deterrence and also identification of those involved in: buildings and/or premises, military, police or public property or personnel.
Unauthorised removal or stealing of articles or goods is an increasing problem. A recent survey has shown that the stealing of articles or goods is predominantly based on opportunism. Such survey showed that unauthorised removal of articles or goods was carried out in a ratio of opportunists to hardened criminals of 80%:20%.
One situation in which unauthorised removal of articles or goods have taken place is in buildings such as parcel distribution centres, warehouses, storage depots, department stores and like buildings. In such locations articles or goods, suitably in the form of parcels, are constantly transported throughout the buildings. During such transportation, it has been discovered that certain parcels have been stolen. In such situation, it is often difficult to catch the thief, particularly when there are a large number of employees operating in the building concerned. In addition to pilfering of articles or goods, in certain circumstances, vandalism has been a problem with the articles or goods not having been stolen but, rather, damaged instead.
Another situation in which unauthorised removal of articles or goods have taken place is in connection with robbery of articles or goods from premises or vehicles. Such unauthorised removal is an increasing problem and it is often difficult for authorities to convict a thief or burglar since it not always possible to prove that the thief or burglar was present at a particular robbery.
Various types of chemicals have been considered for application to the surface of an article, goods or premises. A composition utilising a dyestuff has been proposed, but same is not considered appropriate since the dye can be seen on the article, goods or premises. Another prior arrangment relates to the use of a fluorescent material dispersed in a carrier. The solid fluorescent material is dispersed in a grease and is then smeared onto surfaces or articles liable to unwanted attention. The disadvantages of such arrangement is that the material when applied is greasy or slippy to the touch, and that same is granular because of undissolved particles present therein. Accordingly, the present invention is based on the provision of a composition and method whereby, when such composition is applied to a surface, same cannot be seen; however, when a person touches such surface then that person can be identified.
It is an object of the present invention to provide a composition and method for reducing unauthorised removal of, or damage to, articles or goods or for preventing damage to property.
It is a further object of the present invention to provide a composition and method whereby, when the composition has been applied to a surface, any person who touches such surface can be identified.
It is a still further object of the invention to provide a composition and method for use in buildings and/or premises or with vehicles, wherein said composition is utilised in a sprinkler or like spray system, for identifying the thief or burglar.
According to the present invention there is provided a composition for preventing unauthorised removal of or damage to articles or goods from vehicles, buildings and/or premises or for preventing damage to premises, said composition being colourless, odourless and having no feel thereto, and thereby being undetectable, said composition comprising at least one fluorescent material together with a solvent medium therefor, said medium containing a volatile component said composition, in use, being applied to at least a portion of the surface of such articles or goods or container therefor,
