Indigenous anti-counterfeit ink developed by CSIR-NPL

摘要

The CSIR-National Physical Laboratory (CSIR-NPL), New Delhi - the laboratory that gave us the indelible ink - is all set to launch a high security ink that makes counterfeiting difficult. Dr. Bipin Gupta and his team have described a novel process of manufacturing that makes an all-purpose security ink a reality. The process is reported in Chemistry: A European Journal (DOI: 10.1002/chem.201704076).
