Water-dissipatable polyesters and amides containing near infrared fluorescent compounds copolymerized therein |
摘要 |
Provided are water-dissipatable, sulfo-containing polyesters and polyester-amides having copolymerized therein thermally stable near infrared flourophoric compounds. The polymers are useful in coating or ink compositions, which are in turn useful for marking articles for identification/authentication purposes. Also provided is a method for invisibly marking such articles and a method for detecting and sorting articles by utilizing the near infrared flourophoric ink or coating compositions.
