Fingerprint developers are made of woven or non-woven fabric of hydrophobic synthetic fibers which is impregnated with a 2-cyanoacrylate. The synthetic resin for the fibers may be polyethylene, polypropylene and the like. This developer is placed in a closed vessel together with an article suspected of containing a latent fingerprint with or without a cup of hot water. Rapid development of fingerprints is possible.
