INK FORANTI-COUNTERFEITING BY USING X-RAY SENSING MATERIAL

摘要

An X-ray sensing ink for anti-counterfeiting is provided to sense the forgery of a document by using an X-ray detector and to prevent the forgery of special documents and the outflow of security goods. An X-ray sensing ink for anti-counterfeiting is sensed by comprising an X-ray material through an X-ray detector. The X-ray material and non-visible fluorescent material are included in the amount of 35~65 weight% and 2~10 weight% based on the total weight % of the ink. The non-visible fluorescent material is colorless, is green at ultraviolet rays of short waves(254 nm) and short wave, and is red at ultraviolet rays of long waves(365 nm).
