Embodiment

[0180] Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these Examples. In addition, the parts and % in this invention represent a mass part and mass %, unless there is a notice in particular.

[0181] (hydroxyl value)

[0182] The hydroxyl value is a value obtained by converting the amount of hydroxyl groups in 1 g of the resin into mg of potassium hydroxide, and is obtained in accordance with JIS K0070 (1992). The hydroxyl group is esterified or acetylated and the remaining acid is back-titrated with a base to calculate.

[0183] (amine value)

[0184] The amine value is the number of mg of potassium hydroxide equivalent to the equivalent of hydrochloric acid required to neutralize the amino groups contained in 1 g of the resin. The measuring method of the amine value was performed by the following method.

[0202] [Vinyl chloride-acrylic acid copolymer resin A1]

[0203] In a 1.0L autoclave, make potassium peroxodisulfate (K 2 S 2 o 8 ) 1.0 g was dissolved in 500 g of ion-exchanged water, and degassed. After heating up to 60°C, add 357g of vinyl chloride, 63g of 2-hydroxypropyl acrylate, and 5.0g of di-2-ethylhexyl sodium sulfosuccinate ( Aerosol (aerosol) (OT) mixture 425g, and allowed to react. Polymerization was carried out until the pressure of the autoclave was 2.5 pressure. The prepared emulsion was precipitated with sodium chloride, filtered, washed, and dried to obtain a vinyl chloride-acrylic acid copolymer resin (A1). Furthermore, vinyl chloride-acrylic acid copolymer resin (A1) was dissolved in ethyl acetate, and the 30% solid content varnish (AA1) was obtained. In addition, the content rate of the 2-hydroxypropyl acrylate in A1 was 15.0%, the weight average molecular weight was 50000, and the glass transition temperature was 69 degreeC.

Abstract

One embodiment of the present invention pertains to a non-aqueous printing ink composition which contains a binder resin containing: a vinyl chloride-acrylic copolymer resin (A); and a polyurethane resin (B), wherein the content of a vinyl chloride-derived structure is 75-95 mass% in 100 mass% of the vinyl chloride-acrylic copolymer resin (A).

Description

technical field [0001] Embodiments of the present invention relate to a non-aqueous printing ink composition, and further to a printed matter and a laminate thereof. Background technique [0002] Used in packaging materials such as oriented polypropylene (Oriented Polypropylene, OPP) film, polyethylene terephthalate (PET) film, nylon (nylon, NY) film and other film substrates, coated cardboard paper In the case of a paper substrate such as a paper substrate, an aluminum substrate, or the like, printing using a printing ink is generally performed for decoration or surface protection of the substrate. After the printed substrate is subjected to a slit process, it is sent to a post-processing process such as lamination as the case may be, and finally becomes a package for food packaging, cosmetic packaging, and other uses. [0003] Printing inks can generally be roughly divided into water-based inks and non-aqueous inks. Non-aqueous inks are superior to water-based inks in te...
