摘要: A process for the preparation of a toner by mixing a colorant, a latex, optionally a wax and a polyamine salt coagulant to form toner size aggregates, wherein the polyamine salt is then neutralized or converted to an amide or hydrolyzed to an acid by the introduction of a base followed by a pH reduction with an acid to enable rapid coalescence or fusion of the aggregates.

摘要: Disclosed are marking particles comprising a first polymer a second polymer, a chelating agent, and a spiropyran material of the formula 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.
