BACKGROUND

Conventional xerographic printing systems for toner applications consist of four stations comprising cyan, magenta, yellow, and black (CMYK) toner stations. These and other xerographic printing systems can be made to print specialty colors, including fluorescent toners. A variety of fluorescent toners have been developed, but improved fluorescent toners are desirable.

SUMMARY

The present disclosure provides fluorescent orange latexes and compositions formed from the fluorescent orange latexes, such as toners and inkjet printing compositions. Related methods are also provided.

In one aspect, fluorescent orange latexes are provided. In embodiments, a fluorescent orange latex comprises water and fluorescent agent-incorporated resin particles, the particles comprising a resin, Solvent Red 49 as a red fluorescent agent, and Solvent Yellow 98 as a yellow fluorescent agent, wherein the fluorescent orange latex has a weight ratio of the Solvent Yellow 98 to the Solvent Red 49 in a range of from 20:1 to 0.5:1.

In another aspect, fluorescent orange toners are provided. In embodiments, a fluorescent orange toner comprises fluorescent agent-incorporated resin particles, the particles comprising a resin, Solvent Red 49 as a red fluorescent agent, and Solvent Yellow 98 as a yellow fluorescent agent, wherein the fluorescent orange latex has a weight ratio of the Solvent Yellow 98 to the Solvent Red 49 in a range of from 20:1 to 0.5:1.

In another aspect, methods of making fluorescent orange toners are provided. In embodiments, such a method comprises forming one or more fluorescent latexes which comprise Solvent Red 49 as a red fluorescent agent, Solvent Yellow 98 as a yellow fluorescent agent, a first type of amorphous resin, and a second type of amorphous resin, wherein the Solvent Yellow 98 and the Solvent Red 49 and are present in a weight ratio in a range of from 20:1 to 0.5:1; forming a mixture comprising the one or more fluorescent latexes; one or more emulsions which comprise a crystalline resin, the first type of amorphous resin, the second type of amorphous resin; and optionally, a wax dispersion; aggregating the mixture to form particles of a predetermined size; forming a shell over the particles of the predetermined size to form core-shell particles; and coalescing the core-shell particles to form a fluorescent orange toner.
