光致变色油墨及其制备方法概述

Photochromic Ink and its Preparation Method

对用于钞票、支票、旅行支票、股票、邮票、护照、标签、商标等方面的光致变色油墨研究概况进行叙述,对专利披露的光致变色油墨及其制备方法进行概述.在一种印刷油墨中加入适量的光致变色化合物制成光致变色油墨,并可适用于传统的印刷技术中;为使印刷油墨稳定,可加入适量的稳定剂,以保护光致变色化合物,增加对化学、贴身和热诱导的活化作用的稳定性;为保证光致变色油墨颗粒细小,除用常规方法处理之外,宜采用上海东华高压均质机,可收事半功倍之效.

Research of photochromic ink used in bank notes, checks, traveler＇s checks, stocks, stamps, passports, labels, trademarks and the preparation methods of patented photochromic ink are introduced in the article. Photochromic ink is made from printing ink by adding some photochromic compounds, which can be also applied in the traditional printing technology. In order to improve the stability, suitable amount of stabilizers can be added. Apart from the regular processing method, high pressure homogenizer made by Shanghai Donghua can let the photochromic ink particle fine in an energy and time saving way.
