Abstract

A new class of reagents, 1,2-indanediones, was evaluated for latent print visualization on paper. Tests were carried out for fingerprints and amino acid stains. Selected 1,2-indanediones give fluorescent development superior to DFO. Zinc salt treatment further enhances the sensitivity. The new reagents can be obtained from inexpensive starting materials in a short reaction sequence.
