[0174] 5.1. Preparation of ink

[0175] 5.1.1. Preparation of polymeric ink

[0176] The polymerizable ink was prepared by mixing a photopolymerization initiator, a polymerizable compound, a polymerization inhibitor, and a surfactant according to the composition described in Table 1. In addition, IRGASTABUV-22 (manufactured by Ciba Corporation) was used as a polymerization inhibitor, and BYK-UV3500 (manufactured by BYK Japan KK) was used as a surfactant.

[0179] 5.1.2. Preparation of glossy ink

[0180] Glitter inks were prepared as follows.

[0181] First, polyvinylpyrrolidone (PVP, weight average molecular weight: 10,000) was heated at 70° C. for 15 hours, and then cooled at room temperature. A PVP solution was prepared by adding 1000 g of this PVP to 500 ml of ethylene glycol solution. In another container, add 500ml ethylene glycol, add 128g silver nitrate and fully stir with an electromagnetic stirrer to prepare silver nitrate solution. ...

Embodiment 12

[0245] In Example 12, the polymerizable ink described in Table 1 was recorded on the recording medium shown in Table 2 in a predetermined pattern with a predetermined duty ratio. Then, the recording with the glossy ink was performed at the duty ratios shown in Table 2 thereafter. Finally, the irradiation energy described in Table 2 was irradiated. It should be noted that the irradiation step was performed at the irradiation energy described in Table 2 per 100% duty ratio.

Embodiment 13

[0247] In Example 13, the white-based ink described above was recorded on the recording medium shown in Table 2 at a duty ratio of 100%. Thereafter, the polymerizable ink described in Table 1 was recorded in a predetermined pattern with a predetermined duty ratio shown in Table 2. Then, the irradiation energy described in Table 2 was irradiated. It should be noted that the irradiation step was performed at the irradiation energy described in Table 2 per 100% duty ratio. Finally, the recording of the glossy ink was carried out at the duty ratios listed in Table 2.

[0248] 5.3.4. Comparative example 1~4

[0249] The glossy inks shown in Table 2 were applied to the recording media shown in Table 2 in a predetermined pattern with a % duty ratio shown in Table 2 to form an image.

Abstract

An ink jet recording apparatus includes a first line head that ejects a polymerizable ink containing an active energy radiation-polymerizable compound but substantially not containing a coloring agent onto a recording medium to form an undercoat layer, a second line head that ejects a glittering ink onto the undercoat layer to form a glittering image, a third line head that ejects a coloring ink to form a color image, a transport mechanism that transports the recording medium, an irradiation portion that irradiates the undercoat layer with active energy radiation, and a heating portion that dries the glittering ink. The first line head is disposed upstream from the second line head in the recording medium moving direction, and the third line head is disposed downstream from the second line head in the recording medium moving direction.

Description

technical field [0001] The present invention relates to an inkjet recording device and a recorded matter. Background technique [0002] In recent years, there has been an increasing demand for recorded matter on which glittery images are formed. As methods for recording glossy images, the following methods have been used in the past, namely, a method of pressing metal foil on a recording medium with a smooth surface; a method of vacuum-depositing metal on a plastic film; and coating a glossy image on a recording medium. Sexual ink, and then the method of press processing, etc. However, these methods have problems such as complicated recording steps and limited recording media. Therefore, as shown in Patent Document 1, for example, a technique of recording a glossy image using an inkjet method has been proposed.
