Abstract
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.degree. C. formed by polymerization of an ethylenically unsaturated monomer. The cast coated paper is preferably controlled to have an air permeability 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.
