Latent fingerprint detection method, latent fingerprint detection heat transpiration device, latent fingerprint detection device, and latent fingerprint detection composition

摘要

INDUSTRIAL APPLICABILITY The present invention can be handled easily and can clearly detect latent fingerprints, a latent fingerprint detection method, and a latent fingerprint that can detect a clear latent fingerprint in one operation by warming a medicine at a high temperature in a short time. Provided are a heating transpiration device for detection and a latent fingerprint detection device, and a composition for detecting latent fingerprints. The latent fingerprint detection method of the present invention comprises a heating step of heating a chemical gasified by heating and adhering to the latent fingerprint on the specimen, and an exposure step of exposing the specimen with the latent fingerprint attached in the atmosphere of the gasified chemical. The drug is a mixture of 2-cyanoacrylate polymer and dye.
