Latest Patents

Yamasue's latest patents include a presensitized plate comprising two photosensitive layers. This innovative plate features a roughened and anodized aluminum base, which is coated with a positive working light-sensitive composition layer. The unique aspect of this invention is that the dye concentration in the portion of the light-sensitive layer adjacent to the substrate is lower than in other portions. This design results in less color staining compared to traditional presensitized plates, providing excellent examining properties for plate quality. Additionally, it offers remarkable advantages such as reduced stains around image-deleted areas during printing and high printing durability.

Another significant patent is for a light-sensitive o-quinonediazide printing plate with oxonol dye. This printing plate precursor consists of an aluminum support base with a grained and anodized surface. The surface is coated with a positive working light-sensitive composition and an oxonol dye. This invention boasts high printing durability, excellent water retention ability, and superior color stain resistance. It ensures that the resulting images have high contrast and minimizes color staining, regardless of whether a fresh or fatigued developing solution is used.
