Abstract
Examples of optically clear fluid compositions are disclosed herein. In one example, the optically clear fluid composition includes an aqueous vehicle, an anionic polymeric binder dispersed in the aqueous vehicle, and wax particles incorporated in the aqueous vehicle. The anionic polymeric binder has a glass transition temperature (T) that is higher than 40 C, and a pH ranging from about 7 to about 11. The wax particles have a particle size ranging from about 25 nm to about 75 nm, and a melting temperature (T) ranging from about 100 C to about 150° C. The optically clear fluid composition has a viscosity ranging from about 0.5 centipoise to about 90 centipoise.
