A novel fingerprint-dusting composition based on an organic dye, azure 11, has been prepared. The proportion of the dye in the formulation is 1 per cent, the remaining being an adhesive
mixture of meshed aluminum, boric acid, talc, and barium carbonate. The powder gives sharp and clear prints on a wide range of absorbent and non-absorbent surfaces, including multicoloured ones. Weak, chance prints may be detected under ultraviolet light.
