| titleOfInvention | Fingerprint image generating method and fingerprint image recording sheet |
| abstract | A fingerprint image recording sheet can take a clear fingerprint image easily and efficiently, without the process of wiping seal ink, and with less chance to generate an unclear fingerprint image even in improper operation. A solution containing an electron-donating dye precursor (10) is applied to a fingerprint face (24) of a fingertip and then the fingertip is pressed against a recording film (16) to which an electron-accepting color developer (20) is applied. The electron-accepting color developer (20) adsorbs the electron-accepting dye precursor (10) to occur a coloring reaction on the recording film. The solution containing the electron-donating dye precursor (10) is preferably microencapsulated and applied to a support (12). It is preferable to form the microcapsules (14) to be ruptured merely by rubbing it lightly with the fingertip. |
