Abstract
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.
