Abstract
The present invention relates to colored reflective features, e.g., reflective security features or reflective decorative features, that optionally exhibit color shifting and to inks and processes for making such features. The features, as well as the inks optionally used to form the features, comprise nanoparticles and a colorant that preferably modifies a spectrum of light that is reflected by a reflective layer formed from the nanoparticles. The processes involve forming the features from one or more inks using a direct write printing process.
