Chromatic Technologies Inc. (CTI) has announced the introduction of its photochromic Sunlight Inks for such applications as paper, film and pressure-sensitive labels. According to the company, Sunlight Inks are a breakthrough in chemistry and the first photochromic inks to provide (1) fast kinetics which turn on rapidly when sunlight hits it, (2) repeatability which enables the ink to turn "on and off" forever, (3) a broad color spectrum offering, as well as (4) durability in the sun.

In development for two years, Sunlight Inks are the result of the specialty inks supplier's proprietary technology.
