  • Publication number: 20060251819
    Abstract: The copolymer latex for non-contact coating of the present invention is obtained by emulsion polymerization of a monomer containing from 23 to 58% by mass of an aliphatic conjugated diene monomer, from 0.1 to 7% by mass of an ethylenic unsaturated carboxylic acid monomer, from 5 to 40% by mass of a vinyl cyanide compound, and from 0 to 71.9% by mass of other monomer capable of being copolymerized with the other monomers (provided that the total amount of the monomers is 100% by mass), and polymer particles contained in the latex have an average particle diameter of from 50 to 150 nm. A coating composition for paper containing the latex, a pigment and the like is suitable for a non-contact coating method, such as a curtain coater and a spray, to obtain coated paper excellent in surface strength, printing gloss and the like with good runnability.
