Abstract:
A colored plastic article for colored printing comprising:a plastic substrate comprising a polymer that transmits ultraviolet radiation; anda mutable colorant composition dispersed in the polymer and comprising a mutable colorant, a molecular includant and an ultraviolet radiation transorber which, upon irradiation with ultraviolet radiation, interacts with the colorant to irreversibly mutate the colorant and thereby render the colorant substantially colorless, whereby an image can be printed on the substrate by irradiating selected portions of the substrate with ultraviolet radiation at a dosage level sufficient to irreversibly mutate the colorant at the selected portions.
