The tendency for non-visible light generating chemical light devices to generate undesirable amounts of visible light is obviated by the inclusion of a visible-light absorbing, or wavelength shifting material.

It is intended to provide a method whereby residual detergent (surfactant) can be conveniently and accurately detected in the step of washing or rinsing dishes or clothes, and a test device usable in examining the rinsed conditions. Namely, a method characterized by comprising bringing a test substance with a composition (test agent) comprising an oxalic acid ester, a fluorescent substance, hydrogen peroxide and a strong acid and thus easily detecting the residual detergent sticking to the surface of the test subject from the chemiluminescence thus caused; and a test device which is most suitable for storing the test agent as described above.
The present invention teaches a chemiluminescent device along with a process for its production. The invention specifically relates to a chemiluminescent article of manufacture which includes a containment device and chemical system, both of which may be selected so as to be particularly susceptible to environmental degradation subsequent to their use. In a preferred embodiment the chemiluminescent device is categorized as being biodegradable, i.e. designed to be capable of losing its physical form and re-entering the environment.
The invention provides a chemiluminescent light emitting article having a transparent facestock layer, a chemiluminescent layer comprising at least one chemiluminescent compound and a latent initiator, and an activator layer comprising at least one activating compound operable to react with the latent initiator whereby the initiator causes the chemiluminescent compound to emit light.
