Photo-erasable ink for full color printing
摘要:
An ink compatibility including a dye and surface functionalized photocatalytically active semiconductor nanoparticles is provided. This ink composition enables the reuse of a print substrate, because the surface functionalized photocatalytically active semiconductor nanoparticles bleach the dye under an activating radiation.
