Abstract: Disclosed are marking particles comprising a first polymer, a second polymer, a chelating agent, and a spiropyran material of the formula or wherein n is an integer representing the number of repeat -CH2- units and R is -H or -CH=CH2. The marking particles comprise a core containing the first polymer in which is dispersed the chelating agent and the spiropyran and encapsulated within a shell of the second polymer formulated by an Interfacial polymerization.

Abstract: Disclosed is a free radical polymerization process for the preparation of a thermoplastic resin or resins comprising heating a mixture of a free radical initiator, a stable free radical agent, and at least one polymerizable monomer compound to form a thermoplastic resin or resins with a high monomer to polymer conversion; cooling said mixture; optionally isolating the thermoplastic resin or resins; and optionally washing and drying thermoplastic resin or resins. Related free radical processes are also disclosed for the preparation of mixtures and block copolymer thermoplastic resins. Resins prepared by the disclosed processes possesses a narrow polydispersity and a modality that is controlled by the selection of a free radical initiator and stable free radical agent addition step or steps.

Abstract: An ink set includes a plurality of inks, at least one ink but less than all inks of the ink set including an ink vehicle, colorant and fluorescence agent and remaining additional inks including an ink vehicle, colorant and free of fluorescence agent. At least a first ink grouping and a second ink grouping of the ink set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first ink grouping and the second ink grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first ink grouping as compared to the second ink grouping.
