The present disclosure teaches an article of manufacture using an industrial (or commercial) manufacturing process. The article of manufacture comprises an infrared (IR) luminescent material that emits in the IR wavelength range (e.g., from approximately seven-hundred nanometers (~700 nm) to approximately one millimeter (~1 mm)) after being excited by incident wavelengths of between ~100 nm and ~750 nm (or visible light). In other words, once the material has been exposed to visible light, the material will continue to emit in the IR wavelength range for a period of time, even when the material is no longer exposed to the visible light.

An ink composition comprising a nanomaterial and a liquid vehicle, wherein the liquid vehicle comprises a composition including one or more functional groups that are capable of being cross-linked is disclosed. An ink composition comprising a nanomaterial, a liquid vehicle, and scatterers is also disclosed. An ink composition comprising a nanomaterial and a liquid. vehicle, wherein the liquid vehicle comprises a perfluorocompound is further disclosed. A method for inkjet printing an ink including nanomaterial and a liquid vehicle with a surface tension that is not greater than about 25 dyne/cm is disclosed. In certain preferred embodiments, the nanomaterial comprises semiconductor nanoerystals. Devices prepared from inks and methods of the invention are also described.

A scenario-adaptable color-changing ink and a corresponding solar glass product are provided. The ink includes 7-30 parts by weight of photopolymer, 8-20 parts by weight of photoactive monomer, 1-5 parts by weight of photosensitizer, 30-55 parts by weight of weather-resistant resin, 1-10 parts by weight of curing agent, and 1-15 parts by weight of pearlescent pigment. The pearlescent pigment is at least one interference pearlescent pigments with weather-resistance, which has no color. Each sheet of the pearlescent pigment can be considered as a miniature prism which can break the white composite light into colorful monochromatic light, thus allow the coating of the printing ink to present a beautiful pearl luster and metallic luster. The pattern color which is visible by human is a result of overlaps and interferes of lights that the incident light is multiply reflected and refracted by the sheets of transparent pearlescent pigment.

Described herein are heat resistant inks and coating compositions that, when coated on a substrate, impart the feel of paper. The inks and coating compositions do not degrade when exposed to temperatures of 120° C. or greater.
