Abstract

Various laser marking compositions and related methods are described. The laser marking compositions include a molybdenum metal complex, a tungsten metal complex, or combinations thereof. Marks or other indicia formed on a substrate using the compositions and methods exhibit increased contrast and improved substrate bonding.
