Claims14
A toner composition including a toner particle, the toner particle comprising a core and a shell around the core;
- the core comprising (i) an optional colorant and (ii) a polymer generated from styrene and an acrylate monomer;
- and
- the shell comprising a copolymer formed from the polymerization of styrene, an acrylate monomer, and (iii) a multifunctional ultraviolet light curable acrylate oligomer;
- wherein (iii) the multifunctional ultraviolet light curable acrylate oligomer is present in only the shell.
A toner composition including a toner particle, the toner particle comprising a core and a shell around the core, the core comprising (i) an optional colorant and (ii) a polymer generated from styrene and an acrylate monomer;
- and the shell comprising (iii) a an ultraviolet light curable acrylate oligomer;
- wherein said ultraviolet light curable acrylate oligomer is present in said toner composition in an amount of from about 1 to about 15 percent by weight of the toner composition.
A method for printing and/or coating of a substrate, using at least one curable coating, said method comprising:
- providing a substrate;
- providing a toner composition including a toner particle, the toner particle comprising a core and a shell around the core:
- the core comprising (i) a polymer generated from styrene and an acrylate selected from the group consisting of butyl acrylate, carboxyethyl acrylate, and combinations thereof, and (ii) an optional colorant;
- and
- the shell comprising a polymer generated from styrene, (iii) a multifunctional ultraviolet light curable acrylate oligomer, and an acrylate selected from the group consisting of butyl acrylate, carboxyethyl acrylate. and combinations thereof;
- wherein the core is devoid of (iii) the multifunctional ultraviolet light curable acrylate oligomer;
- applying said toner composition on said substrate;
- and
- curing said toner composition by exposure to ultraviolet light.
A toner composition including a toner particle, the toner particle comprising a core and a shell around the core, the core comprising (i) an optional colorant and (ii) a polymer generated from styrene and an acrylate monomer;
- and the shell comprising (iii) an ultraviolet light curable acrylate oligomer;
- wherein said ultraviolet light curable acrylate oligomer is an epoxy-acrylate, polyester- acrylate, or polyether acrylate.
