Applications of photoerasable colorant composition include photoerasable price markings for pricing goods, documents such as gaming tickets for securely communicating concealed information, photoerasable paint for temporary markings on terrain and structures such as signs, roadways, trees, and buildings, marking instruments such as pens, and wick or felt markers, ultraviolet light exposure indicators, and dry printing. The photoerasable or mutable colorant composition comprises a mutable colorant and an ultraviolet radiation transorber which, upon irradiation with ultraviolet radiation, interacts with the colorant to irreversibly mutate the colorant and thereby render the colorant substantially colorless. The mutable colorant composition may also include a molecular includant.
光致可擦除着色剂组合物的应用包括:用于商品定价的光致可擦除价格标记;用于安全传递隐藏信息的文件(如游戏票);用于在地形和结构(如标志、道路、树木和建筑物)上作临时标记的光致可擦除涂料;标记工具(如笔、灯芯或毛毡标记);紫外线照射指示器;以及干式印刷。可擦光或可变色着色剂组合物由可变色着色剂和紫外线辐射转化剂组成,紫外线辐射转化剂在紫外线辐射照射下与着色剂发生作用,使着色剂发生不可逆的变异,从而使着色剂基本变为无色。可变异着色剂组合物还可包括一种分子包含剂。
