Document Type and Number:
Japanese Patent JP2004148669
Kind Code:
A
Abstract:

To provide an original plate of a heat sensitive lithographic printing plate, which has an excellent printing-out property and sensitivity, free from generation of a scum due to an ablation in an overcoat layer, and eliminates the need for development.

This original plate of a heat sensitive lithographic printing plate has a hydrophilic overcoat layer to be removed on a printing machine. The hydrophilic overcoat layer contains die in which the optical density in a visible light region can be varied by exposure and which has no maximum absorption in a region having a wavelength of 700 nm or longer.
