Abstract: Disclosed herein is an improved marking material, consisting essentially of food quality colorant (such as food coloring), and a carrier (such as water, or vegetable oil or canola oil). A method for using this material for the marking of environmental locations is also disclosed. In one form the material also comprises a propellant, all contained within a pressurized aerosol canister. The aerosol canister embodiment having a valve assembly connected to an actuator and aperture for selectively releasing the marking material. In another form, a pump-style spray bottle is utilized, and in another form a larger fluid container, pump and spray-wand type dispersal unit such as the devices commonly used in lawn and garden care, or equivalent apparatus may be utilized. In these forms, the material may consist of water-based food coloring and/or oil-based food coloring and vegetable oil depending on whether the application is dry surface or snow.

Abstract: A curable film-forming composition is provided, comprising: (a) a curing agent comprising reactive functional groups; (b) a compound comprising functional groups reactive with the reactive functional groups in (a); and (c) a photothermally active material. The composition may further include a catalyst component. Coated substrates are also provided using the compositions described, as well as methods for coating a substrate using the compositions.
