Abstract
A composition includes magnetic particles having a median particle size ranging from about 10 to about 30 microns; and reflective particles having a median particle size ranging from about 1 to about 9 microns, wherein the reflective particles have a lightness at least 10 points higher than the lightness of the magnetic particles. A method of making the composition is also disclosed.

A composition comprising:
- magnetic particles having a median particle size ranging from about 10 to about 30 microns;
- wherein the magnetic particles include a reflector layer, a dielectric layer that is external to the reflector layer, and an absorber layer that is external to the dielectric layer;
- and
- reflective particles having a median particle size ranging from about 1 to about 9 microns;
- wherein the reflective particles have a lightness at least 10 points higher than the lightness of the magnetic particles, and
- wherein the reflective particles include a reflector layer, a magnetic layer, and a dielectric layer.

A method of making a composition, comprising:
- providing magnetic particles having a median particle size ranging from about 10 to about 30 microns;
- wherein the magnetic particles include a reflector layer, a dielectric layer that is external to the reflector layer, and an absorber layer that is external to the dielectric layer;
- providing reflective particles having a median particle size ranging from about 1 to about 9 microns;
- and
- blending, in a liquid medium, the magnetic particles with the reflective particles to form a composition,
- wherein the reflective particles have a lightness at least 10 points higher than the lightness of the magnetic particles, and
- wherein the reflective particles include a reflector layer, a magnetic layer, and a dielectric layer.
