Abstract
A process including article of manufacture, utilizes nanoparticles, such as quantum dots, as pigment or dye-pigment to color an article, via dye-sublimation, printing, coloring, or painting methods. Garments or decorative media are manufactured utilizing these methods to incorporate nanoparticles as coloring agents.
Claims20
A method for coloring an article, comprising:
- (a) providing one of pigment and dye-pigment as a coloring agent, said one of pigment and dye-pigment comprising nanoparticles;
- (b) depositing a pattern of said one of pigment and dye-pigment on a transfer substrate;
- (c) drying the transfer substrate;
- (d) positioning the transfer substrate in contact with a surface of the article;
- and
- (e) at least one of heating and heat-pressing said transfer substrate and article;
- wherein the article and transfer substrate are jointly heated until the nanoparticles sublimate from the transfer substrate and are deposited on the article.
