The present invention relates to oil-based inks, and more particularly,
Related to oil-based ink that has hiding power and does not easily whiten. Conventionally, oil-based inks have used aromatic solvents such as toluene and xylene as the main solvent, which has caused problems with odor and toxicity. Therefore, inks using alcohol-based solvents with low odor and toxicity and metal-containing dyes that are highly soluble in the solvents have been used. There was a problem that the hiding power was weak when writing on a non-absorbing surface. Therefore, it is possible to use nigrosine dye as a dye with hiding power, but when alcohol-based solvent is used as a solvent, the dye has poor solubility, and when writing on a non-absorbing surface in high humidity. , the handwriting becomes devitrified, and the so-called whitening phenomenon occurs (after writing, when the solvent evaporates, the temperature drops on the handwriting due to evaporation, and moisture in the atmosphere condenses,
Handwriting turning white. ) was sometimes seen. The inventor of the present invention basically attempted to solve the above-mentioned problem by using nigrosine dye as a coloring agent and conducting various studies on solvents, resins, additives, etc. The invention consists of nigrosine dye, oil-soluble resin, and cellosolve solvent.
The gist is an oil-based ink containing at least 60 to 80% by weight, 5 to 15% by weight of an alcohol solvent having 4 or more carbon atoms, and a fluorine surfactant. What is particularly important in the present invention is the amount of cellosolve-based solvents and alcohol-based solvents with carbon atoms of 4 or more used, and although it is not clear why this has the effect of preventing the whitening phenomenon, it slows down the evaporation rate. This makes it possible to prevent the temperature drop due to latent heat of vaporization as much as possible, and because it uses an alcohol-based solvent with carbon numbers of 4 or more, it has almost no water absorption, so moisture condensation on the handwriting is prevented. It is thought that this can prevent the phenomenon of whitening. The present invention will be explained in more detail below. Nigrosine dyes are used as coloring agents, and specific examples include dyes represented by CI such as CI Solvent Black 5 and 7, and Solvent Black BPL, Solvent Black SEL, and Solvent Black PUL (Orient Chemical Co., Ltd.). (manufactured by Kogyo Co., Ltd.), Sprit, BIack
Examples include dyes represented by trade names such as 3000, MB, and (manufactured by Chuo Gosei Kagaku Co., Ltd.), which can be used alone or in combination, and the amount used is 5 to 35% by weight based on the total amount of ink. % is preferred.
Further, other dyes may be added as appropriate for complementary colors. Oil-soluble resins are mainly used as binders, and most of the conventionally known ones can be used, but specific examples include rosin resins, rosin-modified resins, ketone resins, alkyd resins, and phenol resins. etc., and the amount used is, considering other materials, relative to the total amount of ink.
5 to 20% by weight is preferred. Cellsolve solvents are mainly used to dissolve dyes or adjust viscosity, and to prevent whitening when combined with alcohol solvents. Specific examples include ethylene glycol monomethyl ether and ethylene glycol monoethyl. Examples include ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethylene glycol diethyl ether, diethylene glycol dibutyl ether, triethylene glycol monomethyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, ethylene glycol phenyl ether, etc. Or they can be used in combination. The amount of Cellsolve solvent used is 60% by weight.
Below, the viscosity will become too high, and above 80% by weight, whitening will occur easily, so the range is 60 to 80% by weight.
More preferably, it is 60 to 70% by weight. Alcohol-based solvents having 4 or more carbon atoms are mainly used to dissolve dyes and prevent whitening, and include butanol, n-amyl alcohol, 3-pentanol, n-hexanol, methylamyl alcohol, and 2-ethyl alcohol. butanol, n-heptanol,
Examples include benzyl alcohol, which can be used alone or in combination, and the amount used is 5
If the amount is less than % by weight, the dissolving power of the dye becomes weak, and
The content is 5 to 15% by weight because it tends to whiten and the viscosity becomes too high if it exceeds 15% by weight. Fluorine-based surfactants reduce surface tension and improve wetting of dyes and solvents. Various types of nonionic, anionic, and cationic surfactants can be used, but they do not interact well with solvents. In consideration of compatibility, nonionic materials are preferred. In addition, the amount used is preferably 2.0% by weight or less based on the total amount of ink, and if wetting of the dye and solvent is taken into consideration, it is 0.5 to 0.5%.
1.0% by weight is preferred. In addition, a preservative, a fungicide, a rust preventive, etc. may be added as appropriate. The ink of the present invention can be obtained by heating and stirring the above-mentioned components at room temperature or with a publicly known device. Examples of the present invention will be described below, and "parts" in the examples indicate "parts by weight." Example 1 Sorbon Black SEL (nigrosine dye, manufactured by Orient Chemical Industry Co., Ltd.) 10.0 parts Varifast Yellow #3104 (complementary color dye, manufactured by Orient Chemical Industry Co., Ltd.) 0.8 parts Rosin resin 6.0 parts Ethylene glycol monomethyl ether 64.0 parts Diethylene glycol monomethyl ether 5.0 parts N-butanol 5.0 parts Benzyl alcohol 2.5 parts Florard Fc-431 (fluorine-based nonionic surfactant, manufactured by Sumitomo 3M) 0.1 part A black oil-based ink was obtained by stirring the above components at room temperature. . Comparative Example 1 A black oil-based ink was obtained in the same manner as in Example 1, except that the same amount of Varifast Black #3806 (metallic dye) was used in place of 10.0 parts of Sorbon Black SEL. Example 2 Sorbon Black SEL 14.0 parts Ester gum (rosin modified resin) 11.0 parts Ethylene glycol monomethyl ether 65.0 parts n-butanol 9.5 parts Phtadient 200 (fluorine-based nonionic activator, manufactured by Neos) 0.5 parts The above ingredients were heated ( 50°C) to obtain a black oil-based ink. Comparative Example 2 65.0 parts of ethylene glycol monomethyl ether of Example 2 was changed to 71.5 parts, and 9.5 parts of n-butanol was changed to 3 parts.
A black ink was obtained in the same manner as in Example 2, except that the ink was changed to 50%.
