Abstract:
An ink jet recording method for recording an image having a metallic luster on a recording medium with an ink jet recording apparatus includes forming an underlayer on the recording medium by applying droplets of a first ink composition containing a first thermoplastic resin to the recording medium and also includes forming a metallic luster layer on the underlayer by applying droplets of a second ink composition containing a metal pigment and a second thermoplastic resin to the underlayer. The glass transition temperature of the first thermoplastic resin is lower than or equal to the glass transition temperature of the second thermoplastic resin. The underlayer is formed at a temperature higher than the glass transition temperature of the first thermoplastic resin.
Abstract:
A method of forming an opaque layer includes forming a first layer by discharging droplets of an ink composition containing a metallic pigment on a record medium by an ink-jet recording process and forming a second layer by discharging droplets of an ink composition containing a white pigment on the record medium by an ink-jet recording process. The opaque layer is formed on the record medium on the side where the first layer and the second layer are formed in a region where the first layer and the second layer overlap each other.
