A photochromic latex ink includes an organic polymer; optionally a colorant, and a photochromic compound. The photochromic ink composition has an average particle size from about 20 nm to about 600 nm. The photochromic ink composition is capable of reversibly converting from a first color to a second color in response to a predetermined wavelength scope.

An ink set is made up of at least three differently colored phase change inks, for example cyan, magenta and yellow, wherein at least one of the colored phase change inks is a photochromic ink that contains a photochromic material. Upon exposure to activating radiation such as ultraviolet light, the at least one photochromic ink changes to a color different from the color of the photochromic ink prior to exposure to the activating radiation.
