CAST COATED PAPER FOR INK JET RECORDING, PROCESS FOR PRODUCING THE PAPER AND INK JET RECORDING METHOD USING THE PAPER

摘要

A cast coated paper for ink jet recording is constituted to include, in lamination: a base paper, an undercoating layer comprising a pigment and an adhesive, and a cast-coating layer comprising a polymer having a glass transition point of at least 40 o C formed by polymerization of an ethylenically unsaturated monomer. The cast coated paper is preferably controlled to have an air of at most 300 sec/100 cc. The undercoating preferably contains a cationic resin, particularly preferably a copolymer of a polyalkylenepolyamine and dicyandiamide. The cast coated paper thus produced with an excellent ink absorptivity suitable for ink jet recording while retaining a high surface gloss.
