Method of producing inkjet recording sheet utilizing slot nozzle spray device

摘要

A method of producing an ink-jet recording sheet containing the steps of: (a) coating a water-based coating composition A to form a layer on a non-absorptive support, the coating composition A containing a hydrophilic binder and inorganic microparticles having an average particle diameter of primary particles of not more than 30 nm, (b) drying the coated layer so as to form a porous ink absorptive layer, and (c) applying a water-based coating composition B on the porous ink absorptive layer across a direction perpendicular to a conveying direction of the non-absorptive support employing a slot nozzle spray device, the slot nozzle spray device having: (i) a coating nozzle for supplying the water-based coating composition B; and (ii) a gas nozzle for ejecting a gas to an aperture portion of the coating nozzle, wherein the water-based coating composition B has a dynamic surface tension of 20 to 55 mN/m.
