Abstract

A two component chemiluminescent composition comprising an oxalate component and a peroxide component together with a fluorescer and a catalyst which comprises a magnesium salt of salicylic acid or a substituted salicylic acid such as magnesium salicylate, magnesium-3,5,6-trichlorosalicylate, magnesium-3,5-dichloro-salicylate or magnesium-3-chlorosalicylate. High intensity chemiluminescent light of long duration is instantly produced when the two components are mixed.

Claims

(a) an oxalate component comprising an oxalate ester and a solvent;

(b) a peroxide component comprising a peroxide compound and a solvent;

(c) a fluorescer contained in the oxalate component and/or the peroxide component;

(d) a catalyst contained in the peroxide component, said catalyst being selected from the group consisting of magnesium salicylate, magnesium-3,5,6-trichlorosalicylate, magnesium 3,5-dichloro-salicylate and magnesium-3-chlorosalicylate.

2. The composition of claim 1 wherein the catalyst comprises magnesium salicylate.

3. The composition of claim 1 wherein the catalyst is present in a concentration of 1×
