|20150245790||LATENT FINGERPRINT DETECTION METHOD, HEATING EVAPORATION DEVICE FOR DETECTING LATENT FINGERPRINT, LATENT FINGERPRINT DETECTION APPARATUS, AND COMPOSITION FOR DETECTING LATENT FINGERPRINT - The present invention provides a latent fingerprint detection, method that is to handle and is capable of clearly detecting a latent fingerprint, and a heating evaporation device for detecting a latent fingerprint and a latent fingerprint detection apparatus which are capable of detecting a clear latent fingerprint by a one-time operation by heating a chemical agent at high temperatures in a short time, as well as a composition for detecting a latent fingerprint. This latent fingerprint detection method includes a heating step of heating a chemical agent to be gasified by heating so as to attach to a latent fingerprint on a specimen, and an exposure step of exposing the specimen having the latent fingerprint attached thereto to the atmosphere of the gasified chemical agent. The chemical agent is a mixture of a 2-cyanoacrylic acid ester polymer and a dye.||09-03-2015|
