Ultraviolet-curable composition for inkjet and recording material

Abstract

The present invention provides an ultraviolet-curable composition for inkjet and a recording material. The ultraviolet-curable composition for inkjet has excellent storage stability and can be appropriately used to form a pattern (printing part) with excellent glossy appearance and excellent abrasion resistance. The recording material has a pattern with excellent storage stability, excellent glossy appearance, and excellent abrasion resistance by using the ultraviolet-curable composition for inkjet. The ultraviolet-curable composition, which is for discharge by an inkjet method, includes a polymerizable compound, a metal powder, and a dispersant. The metal powder is treated by a surface preparation with a fluorinated silane compound and / or a fluorinated phosphate ester as a surface preparation agent. The dispersant is alkaline and has a polymeric structure.

Description

technical field

[0001] The present invention relates to an ultraviolet curable 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 surfa...

Examples

Embodiment 1

[0149] First, a polyethylene terephthalate film with a smooth surface (surface roughness Ra of 0.02 μm or less) was prepared.

[0150] Next, silicone oil was coated on the entire surface of one side of the film.

[0151] Next, a film made of Al was formed by a vapor deposition method on the surface side on which the silicone oil was applied.

[0152] 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.

[0153] 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.

[0159] As shown in Table 1 and Table 2, the composition of the metal particles (the composition of the master batch and the type of compound (fluorine compound) used for surface treatment) is set, and the inkjet composition (ultraviolet curable The type or ratio of the raw materials used in the preparation of the composition) was changed so that the composition shown in Table 1 and Table 2 was changed, and the inkjet combination was produced in the same manner as in Example 1 above. (ultraviolet curable inkjet composition).
