PROBLEM TO BE SOLVED: To provide a latent image printing plate having a membrane exhibiting hydrophobicity by being irradiated with light of higher energy than the band gap energy of a photocatalyst. SOLUTION: The latent image printing plate has the membrane containing the photocatalyst, a hydrophilic compound, and a silicone compound. By emitting light of energy higher than the band gap energy of the photocatalyst to the membrane, the contact angle at 20 deg.C of the irradiated part with water is increased by at least 10 degree than that before the irradiation. |
