Problems solved by technology

[0008] However, if the distance becomes longer, the distance from the ink discharge port of the inkjet head to the landing of the discharged ink on the surface of the corrugated paper becomes longer. Therefore, in the range up to the landing, the ink drop tends to bend excessively (flying). bending, wrong direction), and because the spread of the ink on the surface of the corrugated cardboard is insufficient, there may be problems such as stripes on the printed matter
[0009] In particular, when using a non-absorbent or poorly absorbable recording medium such as corrugated paper that is provided with a colored layer that is difficult to absorb the solvent in the ink on the surface of the aforementioned cardboard as the recording medium, the landing ink is difficult to be absorbed by the recording medium. , and it is difficult to wet and spread on the surface of the recording medium, so the generation of the aforementioned streaks may be significantly visible

Embodiment 1

[0248] 5.2 parts by mass of composition A containing styrene-acrylic copolymer A (glass transition temperature 92° C., acid value 46) and water, 28.6 parts by mass of propylene glycol (manufactured by Asahi Glass Co., Ltd.), purified glycerin (manufactured by Kao Corporation) 16.0 parts by mass, triethanolamine (manufactured by Mitsui Chemicals, Inc.) 0.2 parts by mass, ACTICIDE B-20 (manufactured by Thor GmbH) 0.1 parts by mass, ethylene urea (manufactured by BASF) 5.6 parts by mass, Surfynol 420 (manufactured by EVONIK 0.6 parts by mass manufactured by the company) and 43.7 parts by mass of water were mixed to obtain a primer for inkjet printing ink in which the content of the aforementioned styrene-acrylic copolymer A was 2.5% by mass relative to the total amount of the primer for inkjet printing ink. Paint (Y1).

[0249] Next, as a base material, on the entire surface of one side of a corrugated cardboard with a thickness of 2 mm having a white colored layer on one side, t...

Embodiment 2

[0253] Use the composition B containing styrene-acrylic copolymer B (glass transition temperature 80 ℃, acid value 60) and water to replace the aforementioned composition A, use the content of the aforementioned styrene-acrylic copolymer B relative to The primer for inkjet printing ink (Y2), the recording medium, and the printed matter were obtained by the same method as Example 1 except that the total amount of the primer for inkjet printing ink was 2.5 mass %.

Embodiment 3

[0255] Use composition C containing styrene-acrylic copolymer C (glass transition temperature 96, acid value 149) and water to replace the aforementioned composition A, use the content of the aforementioned styrene-acrylic copolymer C relative to spray Except that the total amount of the primer for inkjet printing ink was 2.5% by mass, the primer for inkjet printing ink (Y3), a recording medium, and a printed matter were obtained in the same manner as in Example 1.

Abstract

The present invention addresses the problem of providing a primer for inkjet printing inks which is capable of preventing the occurrence of streaks in a printed material; a record-receiving medium; and a method for producing the same. The primer for inkjet printing inks is characterized by containing an aqueous medium and one or more vinyl polymers (A) that are selected from the group consisting of vinyl polymers (A1) which have a structural unit derived from an aromatic vinyl monomer, while having a glass transition temperature of from 50 DEG C to 100 DEG C and vinyl halide polymers (A2) which have a glass transition temperature of from 50 DEG C to 100 DEG C.

Description

technical field [0001] The present invention relates to primers for inkjet printing inks. Background technique [0002] In the industry, the method of printing packaging materials and advertising media using inkjet printers is being studied. As said packaging material etc., the corrugated cardboard which has the structure which bonded the corrugated cardboard in the state sandwiched between two cardboards is mentioned, for example. [0003] Examples of the corrugated paper include corrugated paper made of cardboard that easily absorbs solvent contained in ink, and corrugated paper provided with a layer that hardly absorbs solvent in ink on the surface of the cardboard. [0004] As an ink usable for printing on corrugated paper, etc., it is known, for example, to mix an aqueous emulsion resin having a glass transition point of 16° C. or higher and an acid value of 10 mgKOH / g or higher and a pigment so that the solid content becomes 15% by weight or higher. An inkjet printin...
