摘要： Disclosed are a scratch color-developable ink comprising an electron-donating colorless or light-color dye precursor, an electron-accepting color developer and a varnish, wherein a solid particle component contained therein has an average particle diameter of 0.3 to 25 μm, a scratch color-developable ink comprising an electron-donating colorless or light-color dye precursor, an electron-accepting color developer and a varnish, wherein an azaphthalide compound is contained as the electron-donating colorless or light-color dye precursor, and an invisible information printed sheet obtained by printing invisible information on a support with the above scratch color-developable ink.The above scratch color-developable ink makes invisible information visible easily by scratching with a finger nail although the color of an invisible information printed portion is hard to develop by frictional contact during usual handling, gives a high developed color intensity and is free from the occurrence of dust during the visualization of invisible information.
摘要翻译：公开了包含给电子的无色或浅色染料前体，电子接受显色剂和清漆的刮痕显色油墨，其中包含的固体颗粒组分的平均粒径为0.3-25微米，包含给电子的无色或浅色染料前体，电子接受显色剂和清漆的刮刮显色油墨，其中包含氮化萘化合物作为给电子的无色或浅色染料前体，并且不可见通过使用上述划痕彩色显影油墨在支撑体上印刷不可见信息而获得的信息印刷纸。上述刮擦性显影墨水通过用手指指尖轻易地看不见信息，尽管在通常的操作过程中，不可见的信息印刷部分的颜色通过摩擦接触难以发展，给出高度显色的颜色强度并且没有发生在看不见的信息的可视化中的灰尘。
