Title:

COPOLYMER LATEX FOR NONCONTACT COATING AND COMPOSITION COMPRISING THE SAME, AND COATED PAPER AND METHOD FOR PRODUCTION THEREOF

Document Type and Number:

WIPO Patent Application WO/2004/061229

Kind Code:

A1

Abstract:

A copolymer latex for noncontact coating which is produced by the emulsion polymerization of a monomer composition comprising 23 to 58 mass % of an aliphatic conjugated diene monomer, 0.1 to 7 mass % of an ethylenically unsaturated carboxylic acid, 5 to 40 mass % of a vinyl cyanide compound and 0 to 71.9 mass % of another monomer capable of copolymerizing with above monomers (provided that the total amount of monomers is 100 mass %), and contains polymer particles having an average particle diameter of 50 nm to 150 nm; and a composition for paper coating comprising the latex, a pigment and the like. The composition is suitable for use in noncontact coating such as curtain flow coating and spraying, and can be used for producing a coated paper being excellent in surface strength, printing gloss and the like with good operating characteristics.
