  • Patent number: 8940829
    Abstract: Provided are compositions of matter which exist in a powdered, free-flowing form to which water is added preferable just prior to the time of use, to yield flowable liquid compositions which are spreadable, dispersible or sprayable onto various substrates. In some embodiments such free-flowing compositions contain water-soluble styrene/acrylic acid copolymers, and can surprisingly comprise relatively large amounts of water on the order of about 20% or more, while remaining in the form of a free-flowing powder prior to their combination with additional water to yield the spreadable, dispersible or sprayable liquid compositions. By the present disclosure, shelf life concerns are eliminated, as the compositions provided have an essentially indefinite shelf life, and transportation and handling ease are greatly increased over prior art compositions due to less weight by the absence of large relative quantities of water present in prior art compositions.

    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.
