6 s i i 2000 o so Is 00 2560 la IMPROVEMENTS IN OR RELATING TO SECURITY OF ARTICLES, GOODS, VEHICLES OR PREMISES The present invention concernij improvements in or rre2lating 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: a) Unauthorised removal of articles or goods including cash from vehicles, bui:ldings and/or premises, b) Vandalism of articles, goods, buildings and/or premises.

c) Unauthorised entry into restricted areas.

d) Acts, possibly violent, by groups or organisations against state, 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 predomindntly based on opportunism*- Such survey showedthat unauthorised removal of articles or goods wE's car.--ied out in a ratio of opportunists to hardened criminals of 80% One situation in which unauthorised removal of article.9 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. Ina Stich situation, it is often difficult to catch the I -2thief, particularly when there are a large number of employees operating in the building concerned. In addition to pilfering of articles or goods, in certain circumstanc.es, vandalism has been a problem with the articles or goods not having been stolen but, rather, damaged instead.

Another situation in which unauthorised rem 'oval 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 000always 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 :25 in a grease 'and is then smeared onto surfaces or articles liable to unwanted attention. The 9.: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, samne cannot be seen; however, when a person touches such surface then that person can be identified.

i -3 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.

~o According to the present invention there is provided an S anti-tampering composition for detecting or deterring unauthorised removal of or damage to articles or goods from vehicles, buildings and/or premises or for detecting or deterring damage to premises, said composition being colourless, odourless and having no feel thereto, and thereby being undetectable, and being capable of transfer from one surface to another, said composition comprising at least one fluorescent material together with a solvent medium therefor, said medium containing a volatile component.

damage to premises, comprising applying to at least a portion of the surface of said articles or goods, or at least a portion of a property? or surrounding area, or storing ready for application to said surfaces, a composition according to the invention, whereby when the articles or goods have been stolen or damaged, or the property damaged, the fluorescent material(s) contained in such composition is/are transferred to the person involved, which person can then be identified by the use of UV-light.

4. o 0 0 0*o 0 0 0 o~ 9 20 tt It t I 9 Said composition may further include one or more trace elements which can be changed on a batch basis thereby 'permitting different batches to be selectively identified, and thereby negating any defence of accidental contact on previous occasions.

The composition can include one or more of any suitable fluorescent materials. However, it has been found that coumarin, oxazinone, and stilbene derivatives are preferred, but fluorescein derivatives can also be utilised.

it is possible to utilise coumarin derivatives, preferably 7-hydroxy-4-methyl coumarin or 7-diethylamino-4-methyl coumarin. Fluorescein derivatives, preferably sodium fluorescein are also utilisable.

It is possible to utilise a fluorescent material which when exposed to UV light fluoresces in a particular colour, each particular fluorescent material 14u N T L1 4;

-5 being selected for a particular customer, so that when the composition containing the selected fluorescent material is applied to a surface of articles or goods, then any unauthorised removal of s!uch articles or goods can be linked back to the particular customer as the source of goods. This is of use when a thief or burglar is apprehended and the fluorescent material which was transferred to the thief or burglar is identified by the use of UV-light thereby linking the thief or burglar with a particular location.

4.

O 0 200 4. :9t 4 it is further possible to utilise a combination of two fluorescent materials having differing max absorption or emission frequencies. It is possible to identify said two materials by utilising a UJV-absorption spectrum or a fluorescent emission spectrum. Accordingly, such combination of fluorescent materials, when applied to a surface of articles or goods and when transferred to a thief or burglar, can positively link the thief or burglar with a particular location, with no chance of a pleading by the thief or burglar that he had picked up or touchkbed fluorescent material accidentally or innocently.

The fluorescent material IS preferably utilised in spray form and can be combined with various solvent systems and surfactants. The- fluorescentmaterialis suitably present in an amount of 0.1 to by weight of the composition.

The solvent medium preferably comprises a mixture of volatile and non-volatile solvents, The volatile solvent is preferably a low boiling alcohol, preferably isopropyl alcohol or t-butanol. The nonvolatile solvent is preferably isopropyl myristate or glycerol trioleate.

.4 f 15 A 4; Q p 200 tR 15 o a400~ 6 In the case of an aerosol, the composition will also include a propellant, suitably butane and suitably one or more surfactants. The surfactant is preferably polyethylene glycol or polypropylene glycol.

A preferred composition for use in the invention comprises a mixture of a fluorescent material together with isopropyl alcohol as the volatile solvent and isopropyl myristate as the non-volatile solvent.

When applied in spray form the isopropyl alcohol evaporates leaving a film of fluorescent material and isopropyl myristate applied to a selected surface.

It is believed that such combination of solvents is effective either, as the isopropyl alcohol evaporates the fluorescent material becomes supersaturated in the isopropyl myristate layer, or as the isopropyl alcohol evaporates the fluorescent material comes out of solution in a mirocrystalline state due to the cooling effects of the evaporating isopropyl alcohol. In either event, a substantial amount of fluorescent material is present in a very thin layer which cannot be felt, seen or smelt.

Furthermore, when using isopropyl myristate any discolouring or yellowing of the fluorescent material is prevented. Such yellowing is- believed due to a photocyclodinerisation reaction of-the fluorescent material which is less pronounced in the low polarity long chain isopropyl myristate which is used to the composition of the invention.

A preferred aerosol composition comprises gin of fluorescent material, 2.5 gm of isopropyl myristate and 12 ml of isopropyl alcohol in a 150 ml 4 4 4 s 4 *00o 0 "*404 -7 aerosol can. Such composition stays active on the material to which it is applied.

In an embodiment of the invention, the composition is applied immediately prior to an article, such as a dummy parcel, passing through a particular section of a department store or warehouse. The composition is suitably in aerosol form and can be sprayed onto the dummy parcel. In such case, the composition applied to the dummy parcel would be undetectable by sight, touch or smell.

Should the dummy parcel be stolen or be damaged then the employees could be brought together and then the bands of each person in turn would be scanned by UV-light. The thief or vandal would have fluorescent material on his or her hands or clothing and could be so identified.

It can thus be seen that, by utilising the composition and method of the present inventio'n, a thief and/or vandal can be identified. The fluO4,ascent material of the composition of the present invention will remain on the fingers of the thief'or vandal after the article or goods have been removed and possibly *-hidden, whereas previously such would not. have been the case.

The composition and method of the present invention' can be applied in any situation wherein unauthorised removal of or damage to, an article may take place, for example, in the case of transport of goods by motor vehicle, train or aeroplane.

In such situations, it is preferable to use the fluorescent material utilised in the composition of 20 0 09 0* 0 90 9 09 9*9*00 0* 025 0400 0 0094 0. 0 0 0* 0 0*

S*

When such sprinkler system is utilised in premises, the sprinkler system is operated by a burglar alarm and when activated the articles or goods in such premises iii store or on display are sprayed with the fluorescent material as would be any personnel involved in the burglary.

A similar sprinkler system could be utilised with vehicles, particularly road vehicles, arnd be activated by unauthorised entry into the vehicle.

The fluorescent material used ini such sp~rinkler systems can be water based either as a souinora useso. The solutions preferably comprises fluorescein derivatives, coumarin derivatives or diamino stilbene disulphonic acid derivatives at 0.1 20% Solutions in the presence of a polymer latex.

The suspension preferably comprises an oxazinone derivative of 0.1-20% in aqueouis suspension stabilised by anionic surfactants and in the presence of a polymer latex.

The polymer latex is chosen so that it Decomes water insoluble on drying, possibly through some type of cross linking mechanism to which end a cross-linking agent may also be added. Trace elements may be used which would normally be watl-er soluble but are held in place by the molymer matrix. Different polymers may also be used and identified subsequently and therefore also act as 'trace elements'. Polymer combinations may also be used and it can thus be seen

The composition and method of the present invention would suitably be utilised accompanied by warning notices etc., to indicate to any potential thief and/or vandal that the person who removes a particular parcel can be identified.

Whilst specific reference has been made to a thief and/or vandal, it is ciear tiat the composition and u.-.thod of the invention can also be used in identifying a person involved in certain criminal activities. Also, warning notices could also be provided to indicate to any potential criminal that criTfte prevention measures are in place and that the criminal may-be identified.
