| abstract |
In the color changing print of this invention, plural areas are printed by using plural types of color changing inks which develop into different colors from the substantially invisible colorless state by reaction with a color changing agent. By the emergence of print from colorlessness and by giving changes in the appearing colors, unexpectedness and entertainingness are provided so that an attractive education may be realized. |
