Publication number: 20160355040Abstract: The present invention pertains to the field of printing plates and discloses a planographic printing plate and preparation method. The planographic printing plate comprises: a metal substrate, a hydrophobic priming coat formed on a surface of the metal substrate and a hydrophilic graphic layer formed on the priming coat, wherein the hydrophobic priming coat is formed by a hydrophobic primer liquid through curing, the hydrophilic graphic layer is formed by inkjet-printing and curing a printing plate-making ink on the hydrophobic priming coat. The planographic printing plate according to the present invention may be printed by using water-based ink, so it can avoid the environmental pollution caused by using solvent-based ink during planographic printing. Further, through the cooperation of the hydrophobic priming coat formed by the hydrophobic primer liquid and the hydrophilic graphic layer formed by the printing plate-making ink, printed matters with desirable image resolution can be obtained.Type: ApplicationFiled: July 27, 2015Publication date: December 8, 2016Applicant: INSTITUTE OF CHEMISTRY, CHINESE ACADEMY OF SCIENCESInventors: Haihua Zhou, Yanlin Song

Coating material for aluminum substrate for inkjet computer-to-plate and preparation and use of same
Patent number: 9493672Abstract: A coating material for an aluminum substrate for inkjet computer-to-plate and preparation method and use of same. The composition of the coating material is: high polymer 5-40 wt %; nano-sized and/or micro-sized oxide particles 5-30 wt %; organic solvent constituting the remainder. The high polymer is at least one selected from the group consisting of MMA-BMA-MA terpolymer resin, phenolic resin, epoxy resin, polyurethane, polyester, urea-formaldehyde resin, polyvinyl formal, polyvinyl butyral and gum arabic. The preparation method for obtaining the coating material is to mix the ingredients together and stir at room temperature. A spin coating method or a roll coating method is used to coat the coating material onto a clean aluminum substrate having not undergone electrolytic graining and anodic oxidation treatment, and then the substrate is baked, resulting in the required roughness.Type: GrantFiled: July 12, 2012Date of Patent: November 15, 2016Assignee: Institute of Chemistry, Chinese Academy of SciencesInventors: Yanlin Song, Ming Yang, Haihua Zhou, Lianming Yang, Gang Li -
