Abstract
Fluorescing highlights can be provided in selected portions of non-color image areas of a printed toner image using fluorescing dry toner particles, such as fluorescing magenta and fluorescing yellow dry toner particles. Before fixing, each fluorescing dry toner particle comprises a polymeric binder phase and a fluorescing colorant that emits at one or more λmax wavelengths of at least 420 nm and up to and including 690 nm and that is dispersed within the polymeric binder phase.
Claims20
A method for providing a highlighted color toner image, the method comprising:
- developing one or more color latent images using corresponding color toner particles to form a composite color toner image on a first receiver material,
- prior to or subsequently to developing the composite color toner image on the first receiver material, developing one or more selected portions of non-color image areas on the first receiver material with fluorescing dry toner particles to provide a developed fluorescing toner highlight in the one or more selected portions of the non-color image areas,
- transferring the composite color toner image and the one or more developed fluorescing toner highlight in the one or more non-color image areas, to a final receiver material to form a composite color toner image and a fluorescing toner highlight in the one or more selected portions of the non-color image areas, and
- fixing the composite color toner image and the fluorescing toner highlight on the final receiver material,
- wherein, before fixing, each fluorescing dry toner particle comprises a polymeric binder phase and a fluorescing colorant that emits at one or more peak wavelengths of at least 420 nm and up to and including 690 nm and that is dispersed within the polymeric binder phase.
