## CPC

- C09K 11/07: having chemically-interreactive components, e.g. reactive chemiluminescent compositions
- C09K: MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE

## Abstract

A chemiluminescent composition comprising an oxalate and an activator component wherein at least one of said oxalate or activator components contains a fluorescer and at least one of said oxalate or activator components contains an organic polymer. The combined concentration of said organic polymer contained in both components is above 50% by weight of the total composition, and said organic polymer is an insoluble solid. Further, The activator component contains a peroxide at a concentration below 2% by weight of the total composition.

## Claims

### Claim 1

A solid-state chemiluminescent composition comprising an oxalate component and an activator component, wherein the two different components are stored in two separate containers wherein said containers are separated from each other by a breakable barrier such that when said barrier is broken the contents of the two separate containers will mix, wherein one of said containers is used to store an oxalate component, and the other of said containers stores an activator component, wherein at least one of said oxalate or activator components is a viscous mixture, such that said component does not flow freely when removed from said container, and at least one of said oxalate or activator components further contains a fluorescer, and said activator component contains a peroxide at a concentration below 2% by weight of the total composition, and wherein at least one of said oxalate or activator components contains an organic polymer, the combined concentration of said organic polymer contained in both components is above 50% by weight of the total composition, and said organic polymer is an insoluble solid.

### Claim 2

A method for making a solid-state chemiluminescent composition wherein two different components are stored in two separate containers wherein said containers are separated from each other by a breakable barrier such that when said barrier is broken the components of the two separate containers will mix, wherein one of said containers is used to store an oxalate component, and the other of said containers stores an activator component, wherein at least one of said oxalate or activator components is a viscous mixture, such that said component does not flow freely when removed from said container, and at least one of said oxalate or activator components further contains a fluorescer, and said activator component contains a peroxide at a concentration below 2% by weight of the total composition, and wherein at least one of said oxalate or activator components contains an organic polymer, the combined concentration of said organic polymer contained in both components is above 50% by weight of the total composition, and said organic polymer is an insoluble solid.
