Abstract
The thixotropic composition of the instant invention may be cured to a more or less rigid form without the use of a mold. The shaped thixotropic composition includes one of the two components which when combined result in chemiluminescent light. The cured solid is useful in a variety of environments and will emit chemiluminescent light upon addition of a second chemiluminescent component.
Claims19
A chemiluminescent article comprising:
- a first chemiluminescent reactant component including a first chemiluminescent reactant solution and a first particulate resin in amounts effective to yield a uniform dispersion upon admixture thereof and a second particulate resin in an amount effective to yield a porous thixotropic composition defined as having liquid characteristics under shear forces, sufficient cohesive properties to permit formation into a desired shape without a mold in the absence of said shear force, and capable of forming a flexible mass upon addition of heat;
- and
- a second chemiluminescent reactant component separated from said first chemiluminescent reactant component;
- wherein contact between said first and second chemiluminescent reactant components will result in generation of chemiluminescent light.

A process for the production of a chemiluminescent article comprising the following steps:
- admixing a first chemiluminescent reactant solution with a first particulate polymeric resin in an amount effective to yield a uniform dispersion;
- admixing a second particulate polymeric resin with said uniform dispersion in an amount effective to yield a porous thixotropic composition defined as having liquid characteristics under shear forces, sufficient cohesive properties to permit formation into a desired shape without a mold in the absence of said shear force, and capable of forming a flexible mass upon addition of heat upon admixture with said uniform dispersion;
- providing a second chemiluminescent reactant solution, said second chemiluminescent reactant solution separated from said first chemiluminescent reactant solution;
- and
- curing said thixotropic composition by addition of heat to form a porous shape retaining form whereby adding a second chemiluminescent reactant solution to said shape retaining form results in chemiluminescent light.
