Abstract: A phase change ink composition comprising an amorphous component, a crystalline material, a photochromic material and optionally, a colorant, which are suitable for ink jet printing, including printing on coated paper substrates. The novel phase change ink formulation allows the ink to change color when exposed to UV light, reversibly and multiple times, providing an ink suitable for use in security applications.

Abstract: A solid ink composition comprises a crystalline compound, an amorphous compound and a pigment concentrate. The pigment concentrate includes a diester crystalline compound, a dispersant and a pigment (magenta / yellow). The incorporation of such pigment concentrate in the solid ink composition produces a stable ink.
