Cyanoacrylate fingerprint development method

Latent fingerprints are developed by exposing them to vapors generated from a thin film of a storage stable cyanoacrylate monomer and a thixotropic additive in sufficient amount to render the composition substantially non-flowable. The monomer film should have a surface area of at least 129 sq. cm. An envelope package for the monomer composition has inner polyethylene surfaces. The envelope may be peeled open to expose the inner surfaces coated with a film of the composition.

Article containing a thixotropic additive and cyanoacrylate monomer

A process is provided for the presumptive identification of narcotics and drugs of abuse, utilizing a combination of color-producing reagents in a sequence which minimizes the occurrence of false positives, and makes possible the presumptive identification by color matching of virtually all the important narcotics and drugs of abuse found in traffic at the present time.
