Problems solved by technology

[0005] However, for inkjet compositions, when it is intended to use metal powders instead of pigments or dyes, there is a problem that the properties such as the glossiness of the metal itself cannot be fully exerted, and in addition, it may cause the composition to be damaged. Deterioration of stability (storage stability), decrease in ejection stability due to increase in viscosity due to gelation, etc.

Embodiment 1

[0134] First, a polyethylene terephthalate film with a smooth surface (surface roughness Ra of 0.02 μm or less) was prepared.

[0135] Next, silicone oil was coated on the entire surface of one side of the film.

[0136] Next, a film made of Al was formed by a vapor deposition method on the surface side on which the silicone oil was applied.

[0137] Next, the polyethylene terephthalate film (base material) on which the Al film was formed was placed in a liquid composed of diethylene glycol diethyl ether, and ultrasonic vibration was applied. In this way, scaly Al particles (particles that should serve as master batches) were obtained.

[0138] Next, by putting the particles made of Al obtained in the above manner into CF which is a fluorophosphate 3 (CF 2 ) 4 (CH 2 ) 2 O-PO(OH) 2 1% by mass of propanol solution, and stirred for 10 seconds, so that the surface treatment by fluorophosphate ester was carried out, and the metal powder was obtained.

[0139] The average pa...

Embodiment 2～15

[0142] As shown in Table 1, the composition of the metal particles (the composition of the master batch and the type of compound (fluorine-based compound) used for surface treatment) was set, and the type of raw materials used for the preparation of the inkjet composition Or the ratio was changed so that the composition shown in Table 1 was obtained, and an inkjet composition was produced in the same manner as in Example 1 above.

Abstract

The present invention provides a composition for inkjet and a recording material. The composition for inkjet has excellent discharge stability and excellent storage stability and can be appropriately used to form a pattern (printing part) with excellent glossy appearance. The recording material has a pattern with excellent glossy appearance by using the ultraviolet-curable composition for inkjet. A composition adapted to be discharged by an inkjet method includes a metal powder, an organic solvent, and a binder resin. The metal powder is treated by surface preparation with a fluorinated silane compound and / or a fluorinated phosphate ester as a surface preparation agent.

Description

technical field [0001] The present invention relates to an inkjet composition and a recorded matter. Background technique [0002] Conventionally, metal plating, hot-foil printing using metal foil, thermal transfer using metal foil, and the like have been used as methods for producing decorative items that exhibit a glossy appearance. [0003] However, these methods have problems such as difficulty in forming fine patterns and difficulty in applying to curved surfaces. In addition, in hot foil printing, there are problems that the demand is low, it is difficult to adapt to multi-variety production, and printing with layered metallic tones cannot be realized. [0004] On the other hand, as a recording method on a recording medium using a composition containing a pigment or a dye, a recording method using an inkjet method can be used. The inkjet method is excellent in the formation of a fine pattern and can be suitably used for recording on a curved surface. In particular, ...
