Abstract
Described herein are phosphor-containing ink compositions for disinfecting surfaces and improving the photostability of synthetic polymers. Methods for preparing the ink compositions are additionally described.
Claims20
An ink composition comprising:
- one or more inorganic phosphor dopants comprising Ca2-xAl2SiO7;
- a solvent;
- and
- a binder,
- wherein the binder comprises polyketones,
- wherein the ink composition has disinfection properties upon exposure to a UV light source, and
- wherein the one or more inorganic phosphor dopants emit photons with a wavelength of light between about 200 nm and 280 nm.
4 more elements
A UV-curable ink composition comprising:
- one or more inorganic phosphor dopants comprising Ca2-xAl2SiO7;
- one or more photoinitiators;
- and
- one or more monomers,
- wherein the one or more monomers comprise isophoryl acrylate,
- wherein the UV-curable ink composition has disinfection properties upon exposure to a UV light source, and
- wherein the one or more inorganic phosphor dopants emit photons with a wavelength of light between about 200 nm and 280 nm.
