• Thermal paper with security features and security ink therefor

  A thermal paper with a latent image (10) derived from a water-based security ink has more than one means of security. A variable light absorbing and/or transmitting pigment or dye in the ink is a first security means, and a water repelling agent in the ink is a second security means. A pseudo-watermark from the coloration of the ink under ambient conditions may be a third security means. Visible images can be generated from the printed ink upon exposure to UV or infrared light. The security ink includes a carrier for said pigment or dye, and the water repelling agent is dispersed in this carrier in an amount sufficient to render the ink waterproof once dried. By virtue of the waterproof nature of the latent image (10), visible images can also be generated by overwriting the latent image (10) with a water soluble ink.

  一种带有由水基防伪油墨产生的潜影（10）的热敏纸具有一种以上的防伪手段。油墨中的可变光吸收和/或透射颜料或染料是第一种防伪手段，油墨中的防水剂是第二种防伪手段。油墨在环境条件下着色产生的假水印可以是第三种防伪手段。印刷油墨在紫外线或红外线照射下可产生可见图像。防伪油墨包括用于上述颜料或染料的载体，防水剂分散在该载体中，其用量足以使油墨在干燥后防水。由于潜影（10）具有防水性，因此也可以通过用水溶性油墨覆盖潜影（10）来生成可见图像。
