Also disclosed are methods for producing a UV curable toner compositions, the toner compositions produced thereby, and methods of utilizing the UV curable toner compositions in various painting applications.
Claims21
A UV curable toner composition comprising a toner particle;
- wherein the toner particle comprises a core and a shell surrounding the core;
- wherein the core comprises (i) an optional colorant and (ii) a polymer generated from styrene and an acrylate monomer and
- wherein the shell comprises a UV curable acrylate oligomer, the UV curable acrylate oligomer comprising a polyurethane acrylate.
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 surrounding the core, the core comprising (i) a polymer generated from (a) styrene and (b) an acrylate selected from the group consisting of butyl acrylate, carboxyethyl acrylate, and combinations thereof, and (ii) an optional colorant, and the shell comprising (iii) a UV light curable acrylate oligomer, the UV light curable acrylate oligomer comprising a polyurethane acrylate;
- applying said toner composition on said substrate;
- and
- curing said toner composition by exposure to UV light.
