摘要:
An ink jet recording sheet having a high gloss and ink absorbing property and capable of recording clear ink images having a high and uniform color density, includes a cast-coated ink-receiving layer formed on a substrate sheet and containing fine silica particles with an average primary particle size of 3 to 40 nm and an average secondary particle size of 10 to 400 nm and a binder.
摘要:
A cast coated paper for ink jet recording is prepared by a process including the steps of: forming on a base paper an undercoating layer comprising alumina having a bulk density of at most 0.2 g/cm.sup.3 and an adhesive, applying onto the undercoating layer an overcoating liquid comprising a resin to form a wet overcoating layer, and pressing the wet overcoating layer against a heated drum having a mirror-finished surface to dry the overcoating layer, thereby forming a cast-coating layer. The resultant cast coated paper shows not only good gloss and ink jet recording performances (inclusive of ink absorptivity and recorded image density), but also good weather-fastness of recorded images.

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.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.
