Abstract
A thermal negative type presensitized plate provided with an image recording layer hardened by infrared rays on an aluminum support, wherein the aluminum support has on the surface thereof, a grain shape with a structure in which a grained structure with medium undulation with a specified aperture diameter and a grained structure with small undulation with a specified aperture diameter are superimposed. For the presensitized plate, contact characteristics between the image recording layer and the support and scum resistance on a non-image area are kept compatible with each other at a high level, a thermal diffusion depression effect by which an energy generated by exposure can be efficiently used to form an image is excellent, and sensitivity is high.
Claims6
A presensitized plate provided, on an aluminum support, with an image recording layer which is hardened by infrared rays,
- wherein said aluminum support has on the surface thereof, a grain shape in a structure in which a grained structure with medium undulation of 0.5 to 5 μm average aperture diameter and a grained structure with small undulation of 0.01 to 0.2 μm average aperture diameter are superimposed.
A presensitized plate provided, on an aluminum support, with an image recording layer which is hardened by infrared rays,
- wherein said aluminum support has on the surface thereof, a grain shape in a structure in which a grained structure with large undulation of 5 to 100 μm average wavelength, a grained structure with medium undulation of 0.5 to 5 μm average aperture diameter, and a grained structure with small undulation of 0.01 to 0.2 μm average aperture diameter are superimposed.
