Abstract
The present invention provides recording media comprising nanoparticles, methods of stabilizing recording media against electromagnetic radiation (including ultraviolet radiation and radiation in the visible wavelength range), methods for enhancing the substrate independent durability performance of recording media, and methods for color density and hue control. The recording media deliver improved color, better color density control, improved printability, enhanced durability, and increased lightfastness, but also are capable of being printed on all substrates including woven and non-woven fabrics and paper products, without special treatment or other limitations.
Claims33
A recording medium comprising:
- a nanoparticle having a size of less than about 1000 nanometers comprising a polymeric core having at least one colorant disposed on the surface of the core and at least one charged polymer layer disposed on and covering the core;
- and
- a carrier, and wherein the polymeric core has a functional agent disposed therein.
A recording medium comprising:
- a nanoparticle having a size of less than about 1000 nanometers comprising a polymeric core having at least one colorant disposed on the surface of the polymeric core and a protective coating disposed on and covering the polymeric core;
- and
- a carrier, and wherein the polymeric core comprises an organic polymer, an inorganic polymer, a semi-organic polymer, a semi-inorganic polymer, an organometallic polymer or a combination thereof and wherein the at least one colorant comprises at least one dye.
