Abstract
The present invention provides an ink for ink jet recording, in which the formation of a high-quality image is possible, image keeping quality is excellent, the ink is not dried at an ink jet head, and ejection stability is high, wherein the ink for ink jet recording comprises: at least one dye having a specific structure, in which the at least one dye is dissolved or dispersed in an aqueous medium; and a betaine surfactant, wherein, when the ink has been shaken 30 times or more for 10 seconds and allowed to stand for 3 minutes, a bubble height in the ink is 30 mm or less.
Claims17
An ink for ink jet recording comprising:
- at least one dye represented by the following general formula (1), in which the at least one dye is dissolved or dispersed in an aqueous medium;
- and
- a betaine surfactant,
- wherein, when the ink has been shaken 30 times or more for 10 seconds and allowed to stand for 3 minutes, a bubble height in the ink is 30 mm or less:
- 237
- wherein A represents a five-membered heterocyclic group;
- B1 and B2 each represents ═N—, ═CR1— or —CR2═, and when one thereof represents ═N—, the other represents ═CR1— or —CR2═;
- R5 and R6 each independently represents a hydrogen atom or a substituent group, wherein the substituent group represents an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an alkylsulfonyl group, an arylsulfonyl group or a sulfamoyl group, and a hydrogen atom of each substituent group may be substituted;
- G, R1 and R2 each independently represents a hydrogen atom or a substituent group, wherein the substituent group represents a halogen atom, an aliphatic group, an aromatic group, a heterocyclic group, a cyano group, a carboxyl group, a carbamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heterocyclic oxycarbonyl group, an acyl group, a hydroxyl group, an alkoxyl group, an aryloxy group, a heterocyclic oxy group, a silyloxy group, an acyloxy group, a carbamoyloxy group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an amino group, an acylamino group, a ureido group, a sulfamoylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, a heterocyclic sulfonylamino group, a nitro group, an alkylthio group, an arylthio group, a heterocyclic thio group, an alkylsulfonyl group, an arylsulfonyl group, a heterocyclic sulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a heterocyclic sulfinyl group, a sulfamoyl group or a sulfo group, and a hydrogen atom of each substituent group may be substituted;
- and R1 and R5, or R5 and R6 may combine with each other to form a five- or six-membered ring.
An ink for ink jet recording comprising:
- at least one dye represented by the following general formula (1), in which the at least dye is dissolved or dispersed in an aqueous medium;
- and
- a betaine surfactant,
- wherein a bubble height in the ink just after the ink has been shaken 30 times or more for 10 seconds, is 50 mm or less:
- 238
- wherein A represents a five-membered heterocyclic group;
- B1 and B2 each represents ═N—, ═CR1— or —CR2═, and when one thereof represents ═N—, the other represents ═CR1— or —CR2═;
- R5 and R6 each independently represents a hydrogen atom or a substituent group, wherein the substituent group represents an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an alkylsulfonyl group, an arylsulfonyl group or a sulfamoyl group, and a hydrogen atom of each substituent group may be substituted;
- G, R1 and R2 each independently represents a hydrogen atom or a substituent group, wherein the substituent group represents a halogen atom, an aliphatic group, an aromatic group, a heterocyclic group, a cyano group, a carboxyl group, a carbamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heterocyclic oxycarbonyl group, an acyl group, a hydroxyl group, an alkoxyl group, an aryloxy group, a heterocyclic oxy group, a silyloxy group, an acyloxy group, a carbamoyloxy group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an amino group, an acylamino group, a ureido group, a sulfamoylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, a heterocyclic sulfonylamino group, a nitro group, an alkylthio group, an arylthio group, a heterocyclic thio group, an alkylsulfonyl group, an arylsulfonyl group, a heterocyclic sulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a heterocyclic sulfinyl group, a sulfamoyl group or a sulfo group, and a hydrogen atom of each substituent group may be substituted;
- and R1 and R5, or R5 and R6 may combine with each other to form a five- or six-membered ring.
