The liquid is provided with a surface structure and is characterized by a creation of a random surface structure, in particular a structure of mountains and valleys, of the liquid and by the creation of a random particle distribution, preferably a random particle orientation, by blowing a gas such as air onto the unhardened liquid which may be heated if desired. The surface that is thus created has a unique structure that is discernible by the human eye or detectable by camera and may, for instance, have a light/dark change. | 09-22-2011 |
| 20130095230 | METHOD FOR PREVENTING AND/OR DETERRING A CRIMINAL ACT - A method of preventing and/or deterring a criminal act, comprising standardizing a coordinated approach to a coding system for the identification of stolen property; advertising or publishing the method through a coordinated media campaign to maximize the psychological impact on the criminal mind that acts as the deterrent; and (3) sustaining the deterrent effect by equipping and training police forces so as to maximize the effectiveness of identifying and gathering evidence. | 04-18-2013 |
| 20130209665 | FLUORESCENT MATERIAL FOR SELF-ERASABLE WRITING, AUTHENTIC SECURITY LABELING, CURRENCY COUNTERFEIT PREVENTION AND PROCESSES FOR THE PREPARATION THEREOF - The present invention provides a novel fluorescent molecule having formula 1 which exhibit emission color change when in contact with moisture useful for the preparation of fluorescent paper, allowing self-erasable writing, security label for document authenticity, check and prevention of currency counterfeit Compound of formula 1, when coated on paper, results in blue emitting surfaces on which writing is possible using water as ink.

This strategy is used to create a security label for currency bills for checking original and fake currency notes or any other documents for authenticity. The technique is also useful for temporary writing on recyclable papers. | 10-22-2015 |
| 20160001584 | ARTICLE WITH CURVED PATTERNS FORMED OF ALIGNED PIGMENT FLAKES - In a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of the curved patterns increase along the imaginary line from the first point to the second point. When light is incident upon the aligned pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source. | 01-07-2016 |
