Abstract
An ink set contains a first ink containing a compound in which a pyrazolone ring and a thiazole ring are bonded and a second ink containing a compound in which a pyrazolone ring and a pyridinedione ring are bonded. A thermal transfer recording sheet has a first ink layer containing a compound in which a pyrazolone ring and a thiazole ring are bonded and a second ink layer containing a compound in which a pyrazolone ring and a pyridinedione ring are bonded.
Claims6
An ink set separately comprising:
- a first ink containing a compound represented by General Formula (1) shown below;
- and
- a second ink containing a compound represented by General Formula (2) shown below,
- wherein, in General Formula (1),
- R1 represents an alkyl group, an unsubstituted aryl group, an aryl group having a substituent, an acyl group, a carboxy group, an alkoxycarbonyl group, a carboxamide group, an amino group, an alkoxy group, or a cyano group,
- R2 represents an alkyl group, an unsubstituted aryl group, or an aryl group having a substituent,
- R3 represents an alkyl group, an unsubstituted aryl group, an aryl group having a substituent, or a heterocyclic group,
- R4 and R5 each independently represent an alkyl group, and
- when R1 to R3 are the aryl groups having a substituent, the substituent is an alkyl group, an alkoxy group, or a sulfonic acid salt group,
- wherein, in General Formula (2),
- R6 and R7 each independently represent an alkyl group,
- R8 represents a hydrogen atom, an alkyl group, an unsubstituted aryl group, or an aryl group having a substituent,
- R9 represents an alkyl group, an unsubstituted aryl group, or an aryl group having a substituent,
- R10 represents a hydrogen atom, an alkyl group, an unsubstituted aryl group, an aryl group having a substituent,
- or —N(—R11)R12, wherein R11 and R12 each independently represent a hydrogen atom, an alkyl group, or an acyl group and R11 and R12 may be bonded to form a ring, and
- when R8 to R10 are the aryl groups having a substituent, the substituent is an alkyl group or an alkoxy group.
