  • Patent number: 9023981
    Abstract: The use of non aqueous dispersions NADs has enabled the development of fast setting sheet fed inks, for example. However either due to residual monomers or fractions of initiators, these NAD's have an objectionable odor. A chemical means of dramatically reducing the odor of the NAD's is thus presented. In exemplary embodiments of the present invention, such a chemical treatment can include an amine/alkali mixture in a coupling solvent. In exemplary embodiments of the present invention, the coupling solvent can be one or more of an alcohol, glycol or glycol ether, such as, for example, isopropyl alcohol. In exemplary embodiments of the present invention the amine can be an alkyl amine, such as, for example, diethyl amine, or various other amines, whether alone or in combination. In exemplary embodiments of the present invention, the alkali can be one or more of sodium hydroxide, potassium hydroxide and ammonium hydroxide, whether alone or in any combination thereof.

    Abstract: An ink used for direct inkjet printing to plate based on nanometer material and a method for preparing same. Of the baseline total amount of the ink, 5 to 30 wt % is of film-forming resin, 0.01 to 5 wt % is of nanometer or micrometer dye, 30 to 60 wt % is of organic solvent, 0.01 to 5 wt % is of humectant, and water provides the balance; these ingredients are stirred and mixed at room temperature, and after the film-forming resin is completely dissolved, impurities and/or insoluble substances in the present invention are removed by means of multi-level filtering, and the obtained filtrate is the present ink. The ink in the present invention is sprayed on a metal base material surface by an inkjet printer o form a printing pattern which, after curing, can be directly printed on the machine, thus reducing chemical pollution and post-processing processes, while a press run of the printing plate can be up to 100,000 copies at a resolution of up to 175 lpi.

When the polymer is dissolved, the mixed solution is filtered. The filtrate is the water-based ink. The water-based ink is sprayed via a computer-to-plate machine onto a surface of a metal substrate (which may be an aluminum plate, a zinc plate, or a copper plate) to form a graphic region. A printing plate allowing for computer-to-plate printing is acquired after solidification. The printing plate acquired is allowed to achieve a halftone dot reproduction rate between 2 and 99% and a recognition rate of 175 lpi.

  • Patent number: 4886844
    Abstract: A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamide resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquified by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A cationic surfactant which is the salt of the amine of the formula:R--NH--CH.sub.2).sub.n.sbsb.1 (NH--CH.sub.2).sub.n.sbsb.2).sub.n.sbsb.3 NH.sub.2wherein R represents an alkyl having 16-20 carbon atoms and n.sub.1 and n.sub.2 are the same or different and each represents a whole number from 1-3 and n.sub.3 is 0 or 1, is included in the mixture.
