- a pigment composition 4 of the present invention based on CI pigment yellow 13 was obtained in the same manner as in Example 3, except that the same amount of the monoazo compound 2 was used instead of the monoazo compound 1. .
- a conventional pigment composition 3 based on CI Pigment Yellow 13 was obtained in the same manner as in Example 3 except that the same amount of the monoazo compound 3 was used instead of the monoazo compound 1.
- a conventional pigment composition 4 based on CI Pigment Yellow 13 was obtained in the same manner as in Example 3 except that the same amount of the monoazo compound 4 was used in place of the monoazo compound 1.
- Example 26 of Patent Document 1 was traced with slight changes including scales and the like.
- the disproportionated rosin calcium salt was used in place of the disproportionated rosin sodium salt, and the composition ratio was matched with that of Comparative Example 3.
- an acidic aqueous solution at 20 ° C consisting of 60 parts of 80% acetic acid and 10,000 parts of water was prepared in a reaction vessel having a stirrer. A part of the coupler aqueous solution was added to the acidic aqueous solution to adjust to pH 6.2 to prepare a buffer solution.
- a diazo-aqueous solution B was quantitatively supplied over 1 hour. During this time, the coupler should be adjusted so that the pH in the reaction vessel is 5.8 to 6.4. One aqueous solution was also fed into the reaction vessel.
- the pH in the reaction vessel was adjusted to 5.4 using 15% hydrochloric acid.
- a tetrazonium aqueous solution A was quantitatively supplied into the reaction vessel over 3 hours.
- the aqueous coupler solution was also supplied into the reaction vessel so that the pH in the reaction vessel was 4.8 to 5.4.
- disazo pigment composition 3 (CI Pigmentoero 13 and disproportionated rosin calcium salt, monoazo compound 3 and monoazo compound 3 calcium salt). Disazo pigment composition) was obtained.
- the disazo pigment compositions of Examples 3 to 4 contain a calcium salt of a carboxylic acid having an alkylhydrophenanthrene skeleton and a specific monoazo compound in place of the conventional disazo compound.
- a carbohydrate having a disazo pigment and an alkylated hydrophenanthrene skeleton is used. It had a hue and tinting strength almost the same as those of printing inks and coatings prepared from disazo pigment compositions containing a calcium salt of acid.
- the lithographic printing inks prepared for the disazo pigment composition of the present invention in Examples 3 to 4 were more fluid than the conventional disazo pigment compositions of Comparative Examples 3 to 5. It is clear that it is excellent.
- the power of the conventional lithographic pigment composition of Comparative Examples 3 to 5 The prepared lithographic printing ink saturates the glass plate fluidity and stops flowing in a certain period of time.
- the lithographic printing ink prepared by the composition is superior in fluidity compared to the same time, and is less susceptible to fluid saturation.
- Example 26 of Patent Document 1 was slightly changed including the scale etc. so that it could be compared with Comparative Example 3. However, these changes were not made as in Patent Document 1. Even if disproportionated rosin sodium salt is used as it is, or if it is used in the same amount as described, the fluidity of the lithographic printing inks obtained from these facial compositions is the same as in Examples. In addition to the level of 3, it did not reach the level of Comparative Example 3.
- the disazo pigment composition of the present invention of Examples 3 to 4 does not contain a disazo compound or a specific monoazo compound, and has a carboxylic acid (II) having an alkylhyhydrophenanthrene skeleton or a metal thereof. Even when compared with conventional disazo pigments containing salt ( ⁇ ), the lithographic printing ink evaluation was superior in fluidity.
- the disazo pigment composition of the present invention by containing a monoazo compound that is promising for the modification of a specific disazo pigment, it is possible to improve the safety and to change the hue without changing the hue. It is possible to dramatically improve the fluidity of colored materials such as.
- a disazo pigment composition can be easily produced by mixing a disazo pigment and a monoazo compound having a specific structure, and has great industrial significance.
- the lithographic printing ink of the present invention contains the above-mentioned disazo pigment composition and a vehicle for lithographic printing ink, the lithographic printing ink has excellent fluidity without lowering coloring power and dispersibility, and is effective for industrial use. Can be expected.
