Abstract

An oil-based recording liquid according to the invention includes a color material and an oil-based medium, the oil-based medium contains a first organic medium having an SP value of 9.5 or more and an iodine value of 120 or more, and the content of the first organic medium is 50 percent by mass or more, or the oil-based medium contains an allyl compound.

First claim

What is claimed is:

1. An oil-based recording liquid, comprising:
a color material; and
an oil-based medium,
wherein the oil-based medium contains a first organic medium having an SP value of 9.5 or more and an iodine value of 120 or more,
the content of the first organic medium is 50 percent by mass or more, and
the content of a second organic medium having an SP value of 9.0 or less and an iodine value of 100 or less, in the oil-based recording liquid is 30 percent by mass or less.

2. The oil-based recording liquid according to claim 1 ,
further comprising at least one type of drier selected from the group consisting of a metal soap and a metal complex.

3. The oil-based recording liquid according to claim 2 ,
wherein a metal of the metal soap or the metal complex is at least one selected from the group consisting of Co, Mn, Pb, Zr, Ca, Ba, K, and Fe.

4. The oil-based recording liquid according to claim 1 ,
wherein the oil-based medium further contains a dry oil.

5. The oil-based recording liquid according to claim 1 ,
wherein the oil-based recording liquid is used for ink jet recording.

6. An oil-based recording liquid, comprising:
a color material; and
an oil-based medium;
wherein the oil-based medium contains an allyl compound and a dry oil,
wherein the allyl compound is a compound represented by the following formula (1)

wherein in the formula (1), R 1 and R 2 each independently represent an alkyl chain having 1 to 3 carbon atoms, X n represents hydrogen, a hydroxyl group, an alkyl group having 1 to 6 carbon atoms, an alkylol group having 1 to 3 carbon atoms, or an allylalkoxy alkyl group represented by a formula (2),
m represents an integer of 1 to 3, and n represents an integer which satisfies m+n=4, and
R 3 and R 4 each independently represent an alkyl chain having 1 to 3 carbon atoms.

7. The oil-based recording liquid according to claim 6 ,
further comprising at least one type of drier selected from the group consisting of a metal soap and a metal complex.

8. The oil-based recording liquid according to claim 6 ,
wherein the oil-based recording liquid is used for ink jet recording.
