Abstract

See full text

Using the sympathetic printed-matter according to the present invention, a hidden content can be visualized just by wetting. Therefore, it is possible to remove necessities of the sympathetic ink and a special material such as reagent or equipment for visualizing hidden contents. In addition, since the hidden contents disappear by removing water from the sympathetic printed-matter, the sympathetic printed-matter can be used repeatedly. Using the reading confirmation portion, whether or not the sympathetic printed-matter has been read by any other person can be easily determined. In the sympathetic printing method according to the present invention, a hydrophobic substrate can be formed using an existing gas grafting facility, and an ester hydrolase composition and the reading confirmation portion can be formed using an existing printing method. Therefore, a large amount of sympathetic printed-matters can be produced inexpensively and efficiently.
