Patent ID: 8137597

Claim:
A one-part microencapsulated chemiluminescent system comprising: a.) a microcapsule, the microcapsule having an inner core and a liquid impermeable polymer shell surrounding the core; b.) a dye and a hydrophobic solvent contained within the core of the microcapsule; c.) a coating on the outside of the polymer shell, the coating comprising an oxalate and a source of hydrogen peroxide; wherein the liquid impermeable polymer shell serves as a barrier between the dye and the hydrophobic solvent contained within the microcapsule and the oxalate and the source of hydrogen peroxide coating on the outside of the microcapsule polymer shell; and wherein when the shell of the microcapsule is broken, the hydrophobic solvent at least partially dissolves the oxalate and the source of hydrogen peroxide, thereby beginning a chemiluminescent reaction.
