[Niraura Kuruhime - In inks used for printing, etc., the original color of the pigment often changes depending on the raw materials, manufacturing method, printing method, etc., and in particular, the vividness of colors such as bronze is reduced. Various methods have been proposed to prevent or improve this, but no definitive method has yet been found. η to month n (゛shiu 4J
An object of the present invention is to provide an inexpensive compound that improves sharpness by adding a small amount to ink. This is solved by That is, the present invention provides general formula (T) [wherein M is Ca, Mg, Ba, , Zn or C
u, R1 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R2 is a methyl group or a phenyl group, and R3 is R
4 or R50. In addition, R4 and R5 have 1 carbon number.
to 22 7'alkyl groups or cycloalkyl groups, alkenyl groups having 3 to 22 carbon atoms, cycloalkenyl groups, aryl groups, aralkyl groups, and long alkylaryl groups. m and n are average values per molecule, m = 0 to 2, n
The present invention relates to a sharpness improver for inks, characterized by containing at least one chelate compound represented by the formula: =2-m. In general formula (1), preferred substituents for R4 and R5 include methyl group, ethyl group, n-butyl group, octyl group, lauryl group, oleyl group, benzyl group, phenyl group, etc. In terms of the effect of improving clarity,
It is preferable to have a relatively small number of carbon atoms, and it is particularly preferable that one of them has 8 or less carbon atoms. Practically, R] is preferably a hydrogen atom or an n-propyl group, and m, which indicates the abundance ratio to calcium atoms, is O.
2 to 2, preferably 1.5 or less. Specific examples of the compound represented by the general formula (T) include those shown in Table 1. In order to obtain the chelate compound of the present invention, it is common to react, for example, an alkoxide or hydroxide with a β-diketone. There are various types of ink whose visibility is improved by adding the chelate compound of the present invention, including offset ink.For face f'l, there are many types such as carbon black, phthalocyanine blue, brilliant carmine, lake red C, etc. The effect is remarkable with ink using carbon black. The present invention will be explained in more detail with reference to Examples below. Maru Shin Y In order to examine the sharpness improvement effect of the Kire-I compound shown in Table 1 in printing ink, carbon black (trade name rE Mitsubishi-bon MA-8J: manufactured by Mitsubishi Chemical Corporation) and Kire-I were used. 1-Compound was added to No. 4 varnish and kneaded with a Hubermaller (1 n OX 3 times) to obtain a colored oil. Next, this colored oil was spread on colored paper, and observation with the naked eye (sensory test) and reflectance measurement using a spectrophotometer were performed. The composition of the colored oil and the test method are as follows. The results are shown in Table 2. (Composition of colored oil) Brightness - 1 degree - Direction - Agent - Control - - No. 4 varnish 70 parts by weight - Pigment 25
Horn chelate compound 5/1 Riichi'/J-・No. 4 varnish 75 parts by weight・Face L Tomi+
25 Horn (degree of thickening) The degree of thickening was sensory evaluated based on the colored oil in the case of blank. (Visibility) Color tone, blackness, gloss, etc. were sensually evaluated with the naked eye based on a blank colored oil. (Reduction rate of reflectance) The reflectance at a wavelength of 600 nm was measured, and the decrease rate of reflectance was calculated based on the blank colored oil. The larger the number, the higher the degree of blackness. Example 2 Phthalocyanine blue (trade name: rCyani) as a pigment
A colored oil was prepared according to Example 1 using ne Blue LBGJ (manufactured by Sumitomo Chemical Co., Ltd.). The composition of the colored oil and the test method are as follows. The results are shown in Table 3. (Composition of colored oil)! L Ming-Nong - Qi [Marui L / No. 4 varnish 68 parts by weight / Pigment 2877 / Chelate compound 4 Blank / No. 4 varnish 72 parts by weight / Pigment 28/7 (Sharpness) Colored oil in case of blank Color tone, gloss, bronze, transparency, etc. were visually and sensually evaluated based on the following criteria. (Reduction rate of reflectance) The reflectance at a wavelength of 720 nm was measured, and the decrease rate of reflectance was calculated based on the blank colored oil. The higher the number, the clearer the blue color without redness. Table 3 Example 3 Red azo lake (trade name f LionolR) as a pigment
A colored oil was prepared according to Example 1 using ed DIG J (manufactured by Toyo Ink Manufacturing Co., Ltd.). The composition of the colored oil and the test method are as follows. The results are shown in Table 3. (Composition of colored oil) Sengetsu ■1 Improver - Saishi No. 1/No. 4 varnish 65 parts by weight/Pigment 30 Horn chelate compound 5 71 LiX/No. 4 varnish 70 parts by weight/Pigment 30 n (Sharpness ) Based on a blank colored oil, color tone, gloss, bronze, transparency, etc. were visually and sensually evaluated. (Reduction rate of reflectance) Measure the reflectance at a wavelength of 570n-, plan = 11
= The rate of decrease in reflectance was calculated based on the colored oil. The larger the number, the greater the redness. Table 4 Hikari Jsu1-cr+ Effect - As is clear from the results of the examples, when applied to printing inks, the pigments treated with the compounds of the present invention have improved color clarity. In addition, it has the characteristic that it does not thicken due to gelation.
