Definitions

  • the invention is directed to compositions and methods for identifiably marking an object. Specifically, the invention provides for marking an object with a marking composition containing a taggant which can be correlated with a particular source of the marking substance. In one embodiment, a marking substance of the invention can be sprayed on a person at the scene of a crime and permit subsequent identification and verification that the person was at the scene of the crime.
  • Personal defense compositions for repelling an assailant are known. Such products can also be used by police, military or other authorities for controlling unruly crowds or disruptive persons. Some well known products for this use include tear gas or CHEMICAL MACE®. When sprayed on a human or animal, these products may cause pain and discomfort to the attacker, however, they may not effectively disable the attacker.
  • a more potent composition that has become popular in recent years and adopted by many law enforcement personnel and the public in general is pepper spray including capsicum and its chemical equivalents, such as capsaicin. See e *. U.S. Patent No. 5,217,708. While often effective in disabling an attacker, one of the problems with pepper spray is that it can also be lethal. In fact, reports have been filed documenting the death of persons following being sprayed with pepper spray. Small canisters of pepper spray are available to certain members of the general public which may be carried in a pocket, purse, or held in the hand, so that it may be used as a deterrent to a crime against the person or against one's property.
  • pepper spray Unfortunately, one of the disadvantages of pepper spray is that it is so potent, that even an unintentional or accidental release can produce catastrophic results. It is because of this potential for catastrophic results that airline passengers are required to reveal the possession of canisters of pepper spray, and airline personnel routinely confiscate canisters of pepper spray from passengers if it becomes known that a canister is being carried.
  • the assailant if his/her face or some other characteristic of the assailant was not noticed by the victim during the criminal act.
  • DNA analysis and correlation with the DNA of a suspected assailant is DNA analysis and correlation with the DNA of a suspected assailant.
  • DNA technology requires access and possession of some physical part of a suspect believed to be the perpetrator of a crime. If available, analysis of the DNA present in skin, hair, body fluids, etc., collected at the scene of a crime, has been used to identify a suspected assailant. Unfortunately, it can often be difficult for law enforcement personnel to secure the possession of such samples to enable analysis and comparison with the DNA of a suspect.
  • DNA may be useful for identification of a suspect in some situations, external visualization of the suspect, even immediately after commission of a crime, does not reveal that the suspect has been involved in a crime, thus increasing the likelihood that the suspect can flee and potentially avoid prosecution.

  • an “indicator” may be any chemical or biological material which can be identified when a composition containing the indicator is analyzed to determine the indicator's presence. Known methods of analysis can be used to identify the presence of the indicator including, for example, separation, extraction, spectrophotometry, fluorometry, mass spectrometry, gas chromatography, high pressure liquid chromotography, nuclear magnetic resonance spectroscopy, etc. It will be appreciated that the term “indicator” includes an "integrity indicator” as discussed below.
  • an indicator of the invention can be non-reactive.
  • non-reactive means that the indicator does not participate in any chemical reaction that may occur in the composition and it does not undergo chemical change or transformation which would preclude subsequent identification of the indicator's presence in the composition.
  • the indicator will not cause substantial irritation or injury to the surface on which it may be applied.
  • An indicator of the invention can be selected from various families of innocuous compounds including, for example, esters, amides, alcohols, etc.
  • Suitable indicators which are relatively innocuous when applied to an animate object such as a human can, for example, be selected from flavorant and/or fragrance compounds including acetates such as: benzyl; phenethyl; anisyl; geranyl; a-methyl bensyl; p-tolyl; vanillan; amyl; 2-methyl butyl; isoamyl; hexyl; nonyl; decyl; heptyl; octyl; lauryl; cyclohexyl; dimethyl; prenyl; trans-2-hexenyl; linalyl; neryl; and tetrahydrofurfuryl.
  • Compounds not contained in the acetate family may also be utilized. 6
  • an isotopically enriched indicator can serve to authenticate that the indicator is from a particular source. For example, if there is a possibility that a composition including the indicator may be comingled with another source of the compound(s) selected as an indicator, such as a natural source, using an isotopically enriched indicator will permit confirmation that the taggant indicator is from the identifiable composition.
  • suitable stable istopes include hydrogen-2, carbon- 13, oxygen-17, fluorine- 19, nitrogen- 15 and oxygen- 18.
  • an "integrity indicator” is an indicator included in a chemical code that has increased vulnerability to loss, damage or other failure of detection under the conditions in which the taggant may be used.
  • Factors which can affect a failure of detection of an integrity indicator under particular conditions include, for example, molecular size, molecular weight, chemical structure, electrical charge, volatility, etc.
  • an indicator having a volatility greater than other indicators of the taggant can be added to the taggant. The presence of the added volatile indicator in subsequent analysis can confirm that the remaining indicators of the taggant have not been compromised by volatilization.
  • a herein described taggant can be admixed with other components to increase the duration of detectability of the taggant, render a tagged composition visible, increase adhesiveness, increase the surface area that can be coated by the tagged composition, etc.
  • the taggant is selected for ability to disperse homogeneously throughout the composition.
  • Homogeneous dispersion ensures that analysis of any portion of a composition, before or after application, will reveal the entire chemical code correlated with a specific container.
  • an identifiable composition can maintain a homogenous dispersion for at least 6 months to 2 years without the need for shaking or other mixing to redisperse the taggant.
  • a marking substance of the invention can also include a "carrier.”
  • a carrier is a polymer resin matrix, such as an adhesive or coating resin.
  • the carrier can function to facilitate adherence of the taggant to a surface on which the composition is applied and/or preserve or "encapsulate” the taggant in a robust environment. That is, the carrier can preferably withstand a significant amount of abuse and contamination without loss of chemical code information or degradation of the taggant constituents after the carrier has "set-up.” In the present context, "set-up" includes curing or drying. As used herein the term “cure” means 7
  • the carrier has completed reactions that render the carrier infusible or chemically inert, such as completion of cross-linking reactions.
  • dry means that solvents used to keep the resin carrier in a dispensable state, such as a liquid, are no longer present (e.g., evaporated).
  • the marking substance can transfer before drying or after drying but before curing.
  • the marking substance can transfer by exfoliating from, for example, a human assailant, over a period of several days, after curing.
  • the dry time of the carrier can be varied.
  • dry time can be measured in days. In some embodiments, a dry time of between about 1 to 600 seconds, preferably about 30 to 240 seconds is selected as it is fairly quick yet will remain in an undried state long enough to create additional "tell-tale" evidence such as permanent fingerprints, similar to fingerprints left on a paint brush handle when painting.
  • the carrier can also be selected to preserve the taggant, perhaps for many years, thus increasing longevity and the amount of evidence available in, for example, a criminal investigation.
  • the carrier has a viscosity range of about 50 to 1000, preferably about 100 to 200 centipoise at ambient temperatures.
  • the carrier can be chosen for its ability to adhere to human hair, skin, clothing, and most other similar surfaces that it may come into contact with while curing.
  • suitable carriers include alkyds, acrylates, styrenes, etc.
  • One preferred carrier is a polymer resin matrix, such as a phenolic modified alkyd, available as product number 057-5703 from McWhorter Technologies, Minneapolis, MN.
  • a marking substance can also include additives.
  • additives include a solvent for adjusting the viscosity of the carrier. Examples of suitable solvents include acetone, xylene, perchloroethylene, etc. Filler materials such as fumed silica, diatomaceous earth, titanium dioxide, etc., can also be added. One filler material, titanium dioxide, can be added to enhance visibility of a resin carrier.
  • Other additives include one or more drying agents such as cobalt, zirconium and/or other metallic driers which function to enhance cure time of the composition when sprayed onto an object, such as a person or clothing, or when exposed to the atmosphere.
  • a marking substance of the invention can also include a label. As used herein, a "label" refers to a compound that renders the substance visibly detectable. This includes, for example, colored pigments, dyes, fluorescent compounds visible with or without ultraviolet light rays, etc. In an embodiment 8
  • the label will adhere to, and visibly mark human skin, hair, fingernails, etc., for a period of several days despite the exfoliation of the resin matrix that may occur during this interval.
  • the label is not easy to remove by the use of commonly known aqueous or organic solvents such as soap and water, rubbing alcohol, minerals spirits, etc.
  • a suitable label are dyes sold under the trademark DayGlo®, available from DayGlo Corporation, Cleveland, OH.
  • Other suitably aggressive colorants can be used in a dye/resin combination of a marking substance such as Hansa yellow pigment, or iron oxide yellow pigments, etc.
  • a label that is a bright colorant can advantageously provide visual identification of a criminal assailant. This is particularly true if the colorant is conspicuous such as a bright yellow or glowing fluorescent color. Since many police apprehensions of criminals are carried out with the assistance of the general public, a visible colorant can act to alert the public that a marked individual has probably been involved in a crime, thus facilitating the apprehension process. For example, in one embodiment, the inventors foresee a common color scheme for use on packaging, advertising, and included with an identifiable composition to create public familiarity, thus increasing the efficacy of a marking substance product as a deterrent to criminal activity. By combining a label with a resin matrix, the visual identification aspect of the label can be prolonged.
