Abstract

The invention discloses a binder component to record holographic graph information, which comprises the following parts: 10%-50% resin from middle molecular or macromolecular acrylate polymer and spirit or fatsoluble cellulose or cellulose derivant, 2. 5%-5% elasticizer and 40%-87% solvent, wherein the softening point of acrylate is 30-100 deg. c with molecular weight between 30, 000 and 150, 000;the nitrogen content of cellulose or cellulose derivant is between 10.8% and 12. 6%. The invention can be applied in the laser moulding holographic thermoprint film, which can locate de-aluminiumingholographic mark and moulding holographic graph record on the safe line of RMB.

Description

technical field [0001] The invention relates to an adhesive composition, in particular to an adhesive composition suitable for use as a laser holographic hot stamping film, a finely positioned dealuminated holographic label, and a holographic imaging layer on a RMB security thread. Background technique [0002] Laser holographic anti-counterfeiting technology is a comprehensive anti-counterfeiting technology developed in the late 1980s and early 1990s. Its main production process is: the laser holographic pattern is made into a master plate by electroforming, and then turned into an embossed plate. The plate transfers the holographic image to a transparent film coated with an imaging layer under certain temperature and pressure. Due to the particularity of RMB circulation and the strict requirements for anti-counterfeiting, there are also extremely strict requirements for the various properties of the adhesive composition used to carry the holographic image. The adhesive com...
