Abstract

本发明公开了一种温控印刷防伪剂，它由珠光 粉、荧光粉、水银、酒石酸水溶液、稳定剂、表面活性剂 组成。当包装物的口花或封口或其它某一部位印上 标记图案后再印刷上该防伪剂即能起到防伪作用。 鉴别时，在其上稍加温(如用烟头火烤)防伪剂颜色即 行退去，显示出防伪标记图案。冷却后又还原，将防 伪记重新覆盖，反复加温反复如是变化。本防伪剂性 能稳定，退色复原变化迅速，使用方便，安全可靠，成 本低。

Description

本发明涉及一种印刷制剂，特别适应于印刷防伪方面。
以往有一种防伪印刷油墨，这种油墨印刷在包装上之后，能够靠颜色的不同变化来鉴别真伪。它的不足之处在于该油墨只能变色，不能显示厂家的标记，影响使用效果，而且鉴别时一旦被加温变色后，不能恢复原状，影响到商品经营者的销售。
本发明的任务在于提供一种新的印刷防伪剂，印刷在口花、封口或其它包装上之后，一旦受热到较高温度，能够显示出下面的底色和认别标记图案，冷却后即又还原，将防伪标记重新覆盖。
本发明的任务是这样完成的：所需的各种成份按重量比计：
珠光粉4-6，荧光粉4-6，水银0.5-1，酒石酸水溶液0.4-0.8，稳定剂0.2-0.5，表面活性剂0.2-0.5，先将珠光粉、荧光粉研磨成细末、筛分，然后在-25℃的低温下，将其加入水银和酒石酸水溶液中，经过搅拌恢复到常温，以后再加温，当升温导至100℃时加入稳定剂和表面活性剂，加热至140℃时停止加热，静置后即为成品。
当口花或封口或其它包装物的某一部位，印上标记图案后，再印刷上本防伪剂。鉴别时，在其上稍加温（如用烟头火烤）防伪剂颜色即行退去，下面显示出厂家防伪标记，冷却后即又还原，将防伪标记重新覆盖。反复加温如是变化。
本防伪剂性能稳定，多次试验多次有效，且退色复原变化甚为迅速，隔着塑料或玻璃纸加温仍然有效，本防伪剂使用方便，安全可靠，稍加火烤即可起到鉴别真伪的作用，而且成本低。
本发明有如下一个实施例：
所需的各种化学成份，均按重量比计，珠光粉4，荧光粉4，水银0.9，酒石酸水溶液0.6，稳定剂和表面活性剂各为0.25，先将珠光粉、荧光粉研为细末、筛分，然后在-25℃的低温下将其加入水银和酒石酸水溶液中，经过搅拌后恢复常温，以后再加温，当温度升至100℃时加入稳定剂和表面活性剂，继续升温至140℃时，停止加热，静置后即为成品。
