Abstract

PURPOSE:To obtain recording of high picture quality without generation of bleeding, paper wrinkle, etc., by a method wherein the ink drop having the surface tension of a specific value or longer is attached onto a recording medium in a swollen state with its surface tension and thereafter, is dred by heating to be fixed. CONSTITUTION:For reduction of blotting by making an ink drop adhere onto the surface of recording paper in a swollen state, the ink having the surface tension of 50dyn/cm or larger is suitable. The heating temperature of recording paper at which an ink drop is dried to be fixed in a good state free from blotting or the like should preferably be not less than the boiling point of water and not more than the temperature at which the fiber of recording paper is thoroughly dehydrated state and brittle. If, for instance, not less than 10% of glycerol is mixed, the clogging at the discharge opening of ink does not occur and not more than 18% thereof is preferable for obtaining the quick drying property of ink. Further, the ink pH degree of, for instance, 8-10 is preferable for improvement in the filling property into the passage of ink and of the discharging property thereof. Thereby, the recording of high picture quality can be realized regardless of the quality of paper.

By heating and drying the ink droplets while maintaining this ink adhesion state and fixing them on the recording medium, it is possible to perform high-quality inkjet recording without unnecessary ink bleeding or paper wrinkles. It is something.

第一に本発明のインクシェツト記録方法に最適なインク
に関して説明ずろ。First, an explanation will be given regarding the most suitable ink for the ink sheet recording method of the present invention.

Table 2 shows the results of adhesion to the surface of commercially available high-quality paper with a velocity ratio of 60 by discharging the solution at a speed of 1.5 sec.

口部の目詰り防止か可能なものが要求される。However, in the tests shown in Table 2, the ink droplets were retained on the surface of the recording paper, resulting in extremely poor drying properties. Therefore, by preheating and heating the recording paper during inkjet recording,
This method dries and fixes ink droplets that have been recorded in good condition without bleeding or the like. The heating temperature of the recording paper is desirably above the boiling point of water and below the temperature at which the recording paper fibers become completely dehydrated and brittle, and approximately 100 to 1
40°C is suitable. Additionally, solvents that are mixed in to prevent clogging of the ink ejection ports are required to be able to prevent clogging of the ejection ports without reducing the surface tension and impairing the drying properties of the recording ink. Ru.

数種のインクを作成した。Based on the above assumptions and the results in Table 2, several types of ink with a surface tension of 50 clyn/cm or more mixed with various solvents as shown in Table 3 were used to prevent clogging of the ejection port. It was created.

リセリンが適当であることが判明した。Table 4 As shown in Table 4, ink e has the smallest spread and bleeding of Dra I and can obtain clear and excellent print quality, and glycerin is used as a mixed solvent to prevent ink ejection port clogging. It turned out to be appropriate.

乾燥性を評価した結果を第５表に示す。In order to roughly determine the appropriate mixing amount of Serine, inkjet recording was performed in the same manner as in Table 4 while changing the amount of Serine mixed in Ink e, and bleeding, clogging of the ink ejection port, and ink drying properties were evaluated. The results are shown in Table 5.

第５表 ［注］※各インクとも染料混入量は１％。Table 5 [Note] *The amount of dye mixed in each ink is 1%.

※上記溶剤の他に微量の防腐剤を添 加した。*In addition to the above solvent, a small amount of preservative is added. added.

※インク乾燥時間は加熱された記録 紙上で記録インクが乾燥に要する 時間。*Ink drying time is recorded by heating. Recording ink takes time to dry on paper time.

※表面張力はグリセリン混入量に関 係なく　５７〜５８ｄｙｎ／ｃｍであった。*Surface tension is related to the amount of glycerin mixed. It was 57 to 58 dyn/cm regardless.

した。As shown in Table 5, even if the amount of glycerin added is increased, there is almost no effect on bleeding because the surface tension is high. Clogging of the ink ejection orifice will not occur if 10% or more of glycerin is mixed in, and 18% or less is preferable to obtain quick drying properties of the ink. Therefore, it has been found that the main component of the mixed solvent is glycerin, and the most preferable amount is 10 to 18%.

Change the ink tank and use Infusiella as in Table 4).
The recorded results are shown in Table 6.

１０程度が好ましいことが判明した。In Table 6, if the pH is less than 7, the ejected ink will be added to the total number, and it will not be possible to obtain good inkjet.
'J: I can't come. Furthermore, since the ink is strongly alkaline at PHII or higher, the ink erodes the recording paper fibers and is absorbed into the paper surface, causing smearing. From the above results, PH8～
It was found that about 10 is preferable.
