Presensitized plate comprising two photosensitive layers wherein the layer adjacent to the support has a lower concentration of dye than the other layer |
摘要 |
A presensitized plate which comprises a roughened and anodized aluminum plate having provided thereon a positive working light-sensitive composition layer which comprises a dye and can be made soluble in a developer upon exposure to light, wherein the dye concentration in the portion of the light-sensitive layer adjacent to or near the substrate is lower than that in the other portions of the light-sensitive layer. The presensitized plate according to the present invention has less color staining than PS plates of the prior art do and thus has excellent examining properties for plate-quality. The presensitized plate also has remarkable advantages of less stains around image-deleted areas during printing and high printing durability.
