OOH CH2COOR2 (1) The present invention relates to a printing ink that provides printing paper with good running stability and a strong printing film surface, and such printing ink can be used as a sheet-fed offset ink or a heat-set offset 1 as an ink for rotary printing. (Prior art) (However, Rl, R2 and R3 are each carbon TII
.. 6-22 alkyl group or argenyl group.
) 2. The average particle size of amino acid derivatives is 0.1 to 50 μm. Problems such as misregistration, backing, or scratches on the printed surface that occur during sheet-fed offset printing or offset rotary printing can significantly reduce the commercial value of printed materials. Therefore, various methods have been devised to prevent this. ml, improve the printing paper's ability to separate from the blanket by lowering the tack of the ink, or add fine particles such as polyethylene wax, microcrystalline wax, or polytetrafluoroethylene to the ink, or add powders such as starch to the printing surface. Spray and adhere <
<There are methods such as accelerating the drying of the printed coating surface by irradiating it with infrared rays. However, ink tackdown causes printing problems such as smearing and misting, and
Addition of a wax component is effective in improving the strength of the printed film, but it is not necessarily effective in improving paper separation from the blanket. In addition, the scattering of starch particles tends to cause problems when printing or polishing the back side, and when adding fine particles of polytetrafluoroethylene, etc., the gloss of the ink becomes a problem. In other words, the objective is to provide an ink that improves paper release properties and running stability of printed paper, and provides a strong drying film. (Means for Solving the Problem) When adjusting sheet-fed offset ink, offset logical ink, etc., the present inventors have determined that the average particle diameter is 0.1 to 50 μm.
Among the amino acid derivatives represented by the following general formula (1) or (2) in the range of Q, 1 to 20
The present invention has been completed based on the discovery that the above-mentioned drawbacks of conventional printing inks can be solved by containing inks within the range of 10% by weight. R I NHCHCOOH CH2COOR2 (1)
(Problems to be Solved by the Present Invention) The present invention solves the above-mentioned drawbacks of conventional printing inks (wherein R1, R2 and R3 each represent an alkyl group or an alkenyl group having 6 to 22 carbon atoms.) The amino acid derivative used in the present invention has a particle size of 0.1 to
50 μm, preferably 0.5 to 30 μm,
If it is smaller than this range, there will be little effect in improving paper separation from the blanket, and if it is larger, it will cause plate residue or blanket residue during printing.

上する.On the other hand, the addition rate of such amino acids is adjusted within the range of 0.1 to 20% by weight, but if it is less than this, the effect of improving the paper release property from the blanket is small, and if it is too much, the fluidity of the printing ink is decreases, which is not desirable. The printing ink according to the present invention contains 20 to 50% by weight of resin components such as rosin-modified phenolic resin, petroleum resin, alkyd resin, or these oil-modified resins, and 0% of drying oil components such as linseed oil, tung oil, and soybean oil. -30% by weight, 10 to 60% by weight of a solvent such as normal paraffin, isoparaffin, naphthene, α-olefin, or a mixture thereof, pigment components such as organic pigments, inorganic pigments, and natural pigments, and a dryer. Additives such as drying inhibitors O~60
The above-mentioned amino acid derivatives can be obtained by adding the above-mentioned amino acid derivatives at a predetermined time to % of heavy oil, but the invention does not particularly stipulate these preparation methods. How to add at the same time,
A method in which the ink is mixed with the pigment components in advance and then mixed with the remaining ink components, or a method in which the amino acid derivative is added after preparing the ink and then mixed again is used as appropriate. Next, the present invention will be explained in more detail with reference to Examples. Example 1 7 parts of N-lauroyl lysine (Ajinomoto ■: Amihove LL, average particle size 20 μm) was added to 100 parts of TKU Aquares (Toyo Ink ■: sheet-fed TAP plate ink) and mixed with a high-speed mixer. Ink 1 was prepared. Example 2 N-lauryl aspartic acid monoβ-lauryl ester (Ajinomoto ■: Famex A) to 100 parts of TK New Bright (Toyo Ink ■: sheet-fed offset ink)
-12, average particle size lOμm) was added and mixed using a high speed mixer to prepare Ink 2. Example 3 To 100 parts of TK New Bright (Toyo Ink ■: sheet-fed offset ink), 3 parts of N-stearylaspartic acid monoβ-stearyl ester (Ajinomoto ■: Famex A-18, average particle size 15 μm) was added. and mixed with a high-speed mixer to produce Ink 3@A. Example 4 TK New Tough Toyo Ink ■: Heat Set Ink) 100 parts of N-stearylasparagine 1 β
-Stearyl ester (Ajinomoto ■: Famex A-
18, average particle size 15 μm) was added and mixed using a high-speed mixer to prepare Ink 4. Completed 5 N-stearylaspartic acid monoβ-stearyl ester (Ajinomoto ■: Feimex A) per 100 parts of W K Aquares (Toyo Ink ■: heat set ink)
-18, average particle size 15 μm) was added and mixed using a high-speed mixer to prepare Ink 5. Comparative Examples 1 to 5 Table 1 The various inks used in Examples 1 to 5 were used as Comparative Examples 6 to 10, respectively. Printing Test The inks of Examples 1 to 5 and Comparative Examples 1 to 5 were evaluated using an offset printing machine manufactured by Mitsubishi Heavy Industries. The allowable price results are displayed using the following symbols. O...Good Δ...Partially defective The strength of the paint film was also good. The amino acid derivatives used in the present invention are all white crystalline powders with a low refractive index and have high smoothness, so they can be added to ink without impairing the color tone, improving the paper release properties of the ink during printing. The running stability of paper can be improved. Unlike natural wax, paraffin wax, etc. used to improve paper release properties during conventional ink preparation, such amino acid derivatives do not dissolve or swell due to solvents or oils in the ink, and their melting point is 150°. Since it has a high rating of C or higher, it is also advantageous in this respect. This is because, with offset rotary inks, the paper surface temperature may be heated to 100 to 150°C after printing, and at this time, if additives with a low melting point are present, they will melt and cause deterioration of the gloss of the printed matter. In addition, such amino acid derivatives also have a function as a pigment separation agent such as inorganic pigment f1, and by using them, not only the ink separation property and the running stability during printing are improved, but also the ink The clarity and film strength of the film are also improved.
