Title:
INDIVISUAL DISTRIBUTOR OF REACTION LIQUID FOR COLLECTING EMBOSSED PATTERN AND USE THEREOF
Document Type and Number:
Japanese Patent JPH01259839
Kind Code:
A
Abstract:
PURPOSE: To provide an individual distributing device of a reactive solution for forming concave-convex patterns such as a fingerprints and the like making possible to maintain an effect for more than one year during the deposition period of the collected patterns with an easy handling and cheap cost by composing so that the individual distributing system comprises a simple bag made of an impermeable material against the reactive solution of forming the concave-convex patterns such as a hand print, fingerprints and the like and the reactive solution is introduced into the bag, and a perforated medium of uniformly soaking the reactive solution is provided. CONSTITUTION: The individually distributing device for realizing the image of a concave-convex patterns with a high resolving power is obtained by uniformly soaking a controlled amount of a reactive solution into a napkin made of a folded blotting paper. In this case, neither a non-continuity not the local loss of an image contrast are caused at the folded portion of the napkin. The receptor medium for forming the image of the concave-convex patterns may be one sheet of paper, an I.D. card or the every media or documents of the others. The chemical composition of the surface of the paper is included by a single or a plurality of co-reactive substances to be dissolved into a liquid soaked into a perforated medium and to be reactive. A dyestuff once formed should be a stable thing and it is important to don't move according to the elapse of time.
