Abstract
- In this paper, a kind of fluorescent anti-counter feiting acrylate pressure-sensitive adhesive (PSA) label was prepared using 7-hydroxycoumarin and acrylate monomer. First,7-hydroxycoumarin was reacted with 3-bromopropylene and coumarin derivatives were prepared. And thio-terminated intermediate-mercaptan A was obtained by the reaction of the mercaptan group of 2,2สน-(Ethylenedioxy) diethanethiol with the double bond. Then, mercaptan A was reacted with acrylate and a novel fluorescent anti-counterfeiting acrylate PSA was prepared. Finally, a novel fluorescent anti-counterfeiting acrylate PSA label was prepared by coating the adhesive on the PET label. The experimental results showed that with the increasing of mercaptan A content, the tensile strength, shear resistance, thermal stability property and fluorescence of mercaptan A-acrylate PSA were improved. When the content of mercaptan A was 5 wt %, the tack,180° peel strength and shear resistance of mercaptan A-acrylate PSA were No.5 ball, 0.54 KN/m and 87 h, respectively. The mercaptan A-acrylate PSA showed bright blue fluorescence under the ultraviolet lamp. [ABSTRACT FROM AUTHOR]
