    • PROBLEM TO BE SOLVED: To provide an ink for scratch-printing, capable of holding a concealing property against the light of a specific light source, e.g., black light, simple in the constitution, producible in a few steps and easy to produce, and to provide scratch-printed matter.SOLUTION: This ink for scratch-printing contains a substance having, in an ink base agent for offset-printing, a wider band gap than that of the energy of irradiation light, e.g., a substance having a band gap of >4.1 eV and ≤20 eV, or a substance having a band gap of >4.88 eV and ≤20 eV. Concretely, as such substances, magnesium oxide, tantalum oxide, calcium oxide, lithium fluoride and sodium chloride are suitable. The scratch-printed matter 10 is provided by applying the ink for scratch-printing onto a printing substrate material and installing a printing layer 13 for forming concealed characters 12 as a concealed image.
    • 要解决的问题:为了提供用于刮擦印刷的墨水,能够保持针对特定光源的光的隐蔽性,例如黑光,结构简单,可以在几个步骤中生产,并且易于 生产,并提供划痕的物品。 解决方案:用于划痕印刷的油墨含有在胶版印刷用油墨基剂中具有比照射光能量更宽的带隙的物质,例如具有> 4.1的带隙的物质 eV和≤20eV,或具有> 4.88eV的带隙和≤20eV的物质。 具体地,作为这样的物质,氧化镁,氧化钽,氧化钙,氟化锂和氯化钠是合适的。 刮擦印刷物10通过将印刷油墨用于印刷基板材料并安装用于形成隐藏字符12的印刷层13作为隐藏图像来提供。 版权所有(C)2013,JPO&INPIT
