Embodiment 1

[0036] Relative to the content of 80% or more, the thickness is 0.03μm, and the foil area is 1.5~2000μm 2 The aluminum foil sheet contains 100 parts by weight of the aluminum foil sheet, as a binder, contains 100 parts by weight of polyurethane resin, 30 parts by weight of polyester resin, and contains 100 parts by weight of methyl ethyl ketone and 3-methoxy-3-methyl as a solvent. 700 parts by weight of -1-butanol, 50 parts by weight of ethyl acetate, and 300 parts by weight of propylene glycol monomethyl ether were used to produce an ink. The viscosity of the ink was 3900 cps.

[0037] Using the above ink to perform offset printing on the back of the transparent polyester film, it was confirmed that a high degree of specular gloss was visible. In addition, the printed image could maintain a very clear outline while maintaining a 0.1mm blank fine line gap.

Embodiment 2

[0039] Relative to the content of 80% or more, the thickness is 0.02μm, and the foil area is 1.5~2000μm 2 100 parts by weight of the aluminum foil sheet contains 120 parts by weight of polyester resin and 60 parts by weight of cellulose derivative resin as a binder, and 200 parts by weight of methyl ethyl ketone as a solvent, and 3-methoxy-3 -300 parts by weight of methyl-1-butanol, 200 parts by weight of ethyl acetate, and 100 parts by weight of toluene to produce an ink. The viscosity of the ink was 3750 cps.

[0040]Gravure printing was performed on the back of the transparent polyester film with the above ink, and the results confirmed that a high degree of specular gloss was visible. In addition, the printed image could maintain a very clear outline while maintaining a gap of 0.1 mm between thin lines.

Abstract

The invention provides an ink for printing, which is characterized in that the ink contains more than 80 percent of aluminum foil with a thickness under 0.03 mu m and a foil area 1.5 mu m2 to 2000 mu m2 in a datum of accumulated area. The aluminum foil is used as paint. The ink contains adhesive polymer 3 to 200 parts by weight and solvent 500 to 2500 parts by weight relative to the aluminum foil 100 parts by weight, and the viscosity determined by a BM type rotational viscometer is 3500 to 5500 cps in the temperature of 20 DEG C, so that the deformation in a datum of 0.1mm blank thin wire clearance maintenance can be prevented. The invention also provides a printing material using the ink.

Description

Technical field [0001] The invention of the present application relates to an ink used in the manufacture of a printed matter with mirror gloss and a printed matter using the ink. Background technique [0002] In printing inks, an aluminum foil is used as a pigment and a binder and a solvent are blended to form a mirror printing ink. [0003] Incidentally, in the invention of the applicant’s prior application, Japanese Patent No. 3151606, it is proposed that the thickness and foil area are within a predetermined range of values ​​to form a mirror printing ink and the ink based on this The composition of the mirror print. [0004] In the above-mentioned prior-application invention (hereinafter referred to as the "applicant’s prior-application invention"), the thickness and area of ​​the aluminum foil are numerically limited to obtain a relatively high degree of specular gloss. On the other hand, in the preferred viscosity range of 50 Within ~1000cps (measured at 20°C with a BM-typ...
