Embodiment 1

[0095] Using Pigment 1 obtained in Production Example 1, a non-toluene gravure ink was produced. First, 10.0 parts of Pigment 1, 10.0 parts of polyurethane resin, 5.0 parts of resin containing chlorine compounds from DIC Co., Ltd., 11 parts of ethyl acetate, 6 parts of methyl ethyl ketone, 180 parts of steel balls were dispersed for 60 minutes with a paint conditioner (made by Toyo Seiki Co., Ltd.) to obtain a pigment dispersion liquid. Further, 40 parts of polyurethane resin for non-toluene, 11.7 parts of IPA, and 6.3 parts of methyl ethyl ketone were added thereto, and additionally dispersed for 5 minutes with a paint conditioner to obtain a non-toluene polyurethane ink. The viscosity and glossiness of the obtained ink were evaluated.

Embodiment 2

[0097] Except having used the pigment 2 obtained in the manufacture example 2 instead of the pigment 1, the gravure ink was obtained similarly to Example 1, and the viscosity and glossiness were evaluated similarly.

Embodiment 3

[0099] Except having used the pigment 3 obtained in the manufacture example 3 instead of the pigment 1, the gravure ink was obtained similarly to Example 1, and the viscosity and glossiness were evaluated similarly.

Abstract

The invention provides an azo pigment composition as well as a preparation method thereof and an ink composition for gravure and relates to a pigment composition and an oil-based coloring composition for gravure containing the pigment composition. The pigment composition can provide an ink and on the aspect of components of the little environmental load oil-based ink, the prepared ink has the advantages of low initial viscosity, excellent stability of viscosity over time and further high glossiness. As a method for solving the technical problem disclosed by the invention, the pigment composition comprises 1-10 parts of nonionic surfactant according to mass conversion relative to 100 parts of the azo pigment, wherein the nonionic surfactant has a molecular weight of below 1000 and is formed by saturated or unsaturated aliphatic hydrocarbon ether compounds with polypropylene oxide and polyethylene oxide as skeletons.

Description

technical field [0001] The present invention relates to a pigment composition, a method for producing the same, and an oil-based gravure ink composition containing the pigment composition. Get high gloss. Background technique [0002] Gravure inks are widely used for the purpose of imparting beauty and functionality to printed objects. When a gravure-printed object is used as a packaging material, especially when it is used as a food packaging material, lamination processing is generally performed. In this case, various to-be-printed materials and lamination processes are utilized according to the type of content and purpose of use. [0003] The printing ink used in such laminated packaging materials widely uses oil-based gravure inks with polyurethane resins having primary amino groups and hydroxyl groups as binder resins. Its adhesion to various plastic films, blocking resistance, The physical properties of the coating film such as lamination strength and boiling / retort...
