Abstract: A coating designed to transfer on impact from a ballistic projectile onto a target. Due to the many possible applications for which this might find use, it has been designed to allow as open-ended a range of application as possible by separating the requirements of the marking system from the requirements of the projectile substrate. To this end the coating is designed to be applied to a wide range of materials and shapes. The coating itself is therefore independent of whatever carrier it is coated onto which allows the carrier to be selected for its own suitability for the application rather than conditional upon compatibility with the marking system.
