Photodegradable Toners for Electrophotography IV. Optimum Terpolymer Composition and UV Irradiation Conditions for Accelerated Photodegradation and Suppressed Photocrosslinking of Matrix Resin

摘要

In the case of the toner (powder ink) image of photocopy, the powders containing colorant particles inside are fixed on the substrate or to each other by partial fusion of matrix resin on the toner surface. It is then easy to detach the image and to recover the substrate by unbinding the fixed colorants. The image of photodegradable toners was proposed to be detached from the substrate by mechanical action after near/mid ultraviolet (UV) or deep UV (DUV) light irradiation for reuse of the poly(ethylene terephthalate) (PET) or paper substrate.
