1. a kind of method of imaging, including:

  • Melting includes the radiation curable phase change ink of following components:

    Radiation curable material,Polymeric dispersant, this polymeric dispersant is selected from the copolymer of styrene-based, the copolymer of alpha-olefin, vinylpyridineThe copolymer of the copolymer of pyridine, vinyl imidazole, polyester copolymer, polyamide copolymer and vinyl acetal,Including pigment, dyestuff, the mixture of dyestuff, the mixture of the mixture of pigment, dyestuff and pigment optional non-fluorescenceColorant, andFluorescent nanoparticle composition, whereinDescribed fluorescent nanoparticle composition includes nanoscale benzothioxanthene granules of pigments, and this benzothioxanthene granules of pigments includesThere is the benzothioxanthene pigment of at least one functionalized moiety, and at least one each have at least one functional group space bigThe functional group of volume stability immunomodulator compounds, the functionalized moiety on wherein said benzothioxanthene pigment and described stabilizer compoundsCombine via hydrogen bond, Van der Waals force and aromatics π

    -superposition, it controls the crystallization of described nanoscale benzothioxanthene granules of pigments, andAndDescribed nanoscale benzothioxanthene granules of pigments has the putting down less than 150nm being obtained by the imaging of transmission electron microscope artAll particle length and average grain width less than 30nm,Radiation curable phase change ink is ejected into image and accepts on base material, radiation curable phase change ink forms gel whereinState;

    Make image accept the radiation curable phase change ink on base material and be exposed to ultraviolet light, solidification radiation curable phase change inkCurable components.
