Abstract

It is impossible to use general latent fingerprint developing reagents with thermal paper because it is very sensitive to change its color when exposed to heat and polarized solvents. The present study set up the applicapable ratio of 1,2-Indanedione solution demonstrating the effect of zinc chloride. There is no difference in results and the term of validity in solution containing under 3% of polarized solvent. And the solution without zinc chloride has better result in fluorescence.
