Abstract:
A coating composition for application over a retroreflective substrate, a retroreflective article comprising a coating formed from the coating composition, and a method of production thereof are provided. The coating composition comprises a pigment suitable to absorb and/or scatter electromagnetic radiation in a wavelength range of 800 nm to 2000 nm. The coating comprises a ratio of reduction in electromagnetic radiation retroreflectance at a wavelength of 905 nm and/or 1550 nm to reduction in electromagnetic radiation retroreflectance averaged over a wavelength range of 400 nm to 700 nm of at least 2:1.
