The present invention relates to a W/O type emulsion ink. During printing, a part of the oil-based ink becomes particles or filaments and is scattered into the air due to centrifugal force and static electricity in the mixing roll of the printing press. The so-called misting phenomenon contaminated printing machines and printed matter, and also had an adverse effect on printing workers. In addition, ordinary oil-based inks are flammable because they are made of vegetable oil, synthetic resin varnish, natural resin varnish, or mixed varnishes thereof, petroleum-based solvents, pigments, and the like. In addition, the amount of calories burned during combustion is high, especially in the case of low viscosity ink of 200 poise or less, which is completely in a liquid state, which poses a problem of increasing the risk of fire. Emulsion inks have been developed as inks that do not have these drawbacks, but in general emulsion inks, the main aqueous component is alcohol, and even if water is used, there are problems with storage stability. Since the amount of water added is small and the viscosity is high, it is unsuitable for heavy printing, so it cannot fully satisfy both effects, and it cannot be expected to produce excellent printed matter. The present invention has been completed in order to solve the above problems and to obtain excellent printed matter. That is, the present invention is characterized in that 0.1 to 2.0 parts by weight of a nonionic activator of HLB 7 to 13 and 80 to 100 parts by weight of an aqueous component consisting of water and polyhydric alcohol are added to an oil-based ink to form an emulsion. /O type emulsion ink. Describing the present invention in detail, as the oil-based ink, a normal oil-based ink consisting of vegetable oil, synthetic resin varnish, natural resin varnish, or a mixed varnish thereof, a high-boiling petroleum solvent, and pigment can be used. In the present invention, HLB7 is used as a nonionic activator.
~13 are used. When the HLB is less than 7, a stable emulsion cannot be formed at room temperature, and when the HLB is greater than 13, the emulsion cannot be broken properly during printing. Such nonionic activators for HLB7-13 include polyoxyethylene alkyl ether,
One or more types of activators such as polyoxyethylene alkyl phenyl ether, polyoxyethylene sorbitan fatty acid ester, and polyoxyethylene fatty acid ester can be used. In addition, the nonionic activator is used for oil-based ink 100
0.1 to 2.0 parts by weight, preferably
Use 0.1 to 1.0 parts by weight. If it is less than 0.1 part by weight,
The nonionic activator has no effect, and if the amount exceeds 2.0 parts by weight, the emulsion cannot be broken properly during printing, making it unstable for heavy printing and resulting in poor print quality. Further, in the present invention, as the aqueous component, a mixture of water and a polyhydric alcohol is preferably used, with 8 to 50 parts by weight of the polyhydric alcohol mixed with 100 parts by weight of water. Furthermore, 80 to 100 parts by weight of the aqueous component is used per 100 parts by weight of the oil-based ink. In the present invention, by emulsifying the oil-based ink using the aqueous component in such a ratio, the evaporation of the aqueous component on the printing press can be prevented, thereby ensuring a sufficient amount of the aqueous component necessary for lithographic printing. Supply became possible. At the same time, it becomes an emulsion ink that is extremely stable at room temperature, and has significantly improved storage stability.Moreover, the emulsion can be easily destroyed by cooling to below 15℃ and applying a shearing force of 50dyne/cm2 or more during printing. be able to. Furthermore, excellent printed matter can thereby be obtained. Note that the alcohol used in the present invention is
One or more polyhydric alcohols such as glycerin, polyethylene glycol, diethylene glycol, and ethylene glycol are preferred. The emulsion ink of the present invention is made into an emulsion by the above composition and operation, and therefore, during printing, the stringiness that occurs when the ink film is separated from the mixing roller part of the printing machine is reduced, and the static electricity is reduced. This greatly reduces ink scattering, thereby solving contamination of the printing press and printed matter as well as hygienic problems for printing workers. In addition, since it is an emulsion ink that mainly contains water as its aqueous component, it is free from flammable substances and flammability unlike oil-based inks, which eliminates the need for special fire prevention equipment in the printing workplace, which is a major advantage in terms of printing work equipment. Also occurs. Furthermore, as described above, the emulsion ink of the present invention is extremely stable at room temperature and has excellent stability in storage and on a printing press. However, when printing, it must be cooled to below 15℃ and 50d
The emulsion is destroyed by means of applying a shearing force of yne/cm 2 or more, and has the property of supplying oil-based ink to the image area and aqueous component to the non-image area, and therefore, excellent printing can be achieved. Examples will be described below. In the examples, parts indicate parts by weight. Example 1 Varnish formulation Varnish A: Maleated petroleum resin (Neopolymer 120 manufactured by Nippon Oil Co., Ltd.) 47 parts Spindle oil 53 parts Gel varnish B: Rosin modified phenolic resin (Tamanol 354 manufactured by Arakawa Chemical Co., Ltd.) 34 parts Machine Oil 31 parts Spindle oil 31 parts Aluminum stearate 4 parts Varnish C: Gilsonite 25 parts Machine oil 75 parts Oil-based ink formula carbon black 14 parts Hakuenka DD (calcium carbonate manufactured by Shiroishi Kogyo Co., Ltd.) 5 parts Varnish A 27 parts Gel varnish B 7 Part Varnish C 11 parts Linseed oil 4 parts Machine oil 6 parts Spindle oil 24 parts Cyanine Blue 1 part Polyoxyethylene alkyl phenyl ether activator (Liponox NCE manufactured by Lion Oil Co., Ltd.)
HLB10.0) 1 part Water-based component formulation Water 84 parts Glycerin 16 parts Stir and mix 90 parts of the water-based component to 100 parts of the oil-based ink (containing nonionic activator) according to the above formulation.
An O-type emulsion ink was produced. This emulsion ink was very stable at room temperature, and the emulsion was easily destroyed by applying a shearing force of 100 dyne/cm 2 at a temperature below 15°C. Therefore, the kneading roller closest to the offset plate passes this emulsion ink through water and heats it to 15°C.
When used in a lithographic printing machine cooled as follows, good printed matter was obtained. Furthermore, the amount of misting generated was about 1/10 or less compared to oil-based ink, and there was no flammability. Example 2 Oil-based ink formulation Carbon black 18 parts Varnish A 28 parts Gel varnish B 7 parts Varnish C 10 parts Linseed oil 5 parts Machine oil 6 parts Spindle oil 23.4 parts Cyanine Blue 2 parts Polyethylene glycol monooleate activator (Kao Atlas Emanone 4110HLB11.7)
1 part Aqueous component formulation Water 80 parts Glycerin 20 parts 100 parts of the aqueous component was stirred and mixed with 100 parts of the oil-based ink (containing a nonionic surfactant) according to the above formulation to prepare a W/O emulsion ink. This emulsion ink had similar properties to the emulsion ink of Example 1. Further, when printing was performed using a similar printing machine, similar good results were obtained. 2 shows changes in dynamic elastic modulus due to temperature changes of emulsion inks in Examples 1 and 2.
