1. A print material, comprising:
a vinylic molecule;
a vinylic cross-linker molecule having a plurality of vinyl groups;
a light-scattering particle having a surface composition;
a quantum dot having a surface composition; and
a polymer dispersant having a functional group from the group consisting of a phosphate group, a phosphonate group, a phosphorus acid group, a sulfate group, a sulfinic acid group, a nitrate group, a carboxylate group, a silyl group, an acidic pendant group, or a combination thereof, wherein the polymer dispersant has a chemical affinity matched to the surface composition of the light-scattering particle and matched to the surface composition of the quantum dot.
