Abstract
Provided is a yellow toner which provides a sharper color than ever before in small amounts and which has excellent light resistance. A yellow toner comprising a binder resin and a yellow colorant, wherein a compound A represented by the following general formula (1) and a compound B represented by the following general formula (2) are contained as the yellow colorant, and wherein a total content of the compound A and the compound B is from 3 to 30 parts by mass with respect to 100 parts by mass of the binder resin, and a mass ratio of the content of the compound A to the content of the compound B (compound A/compound B) is from 0.8 to 20:
Claims5
A yellow toner comprising a binder resin and a yellow colorant,
- wherein a compound A represented by the following general formula (1) and a compound B represented by the following general formula (2) are contained as the yellow colorant, and
- wherein a total content of the compound A and the compound B is from 3 to 30 parts by mass with respect to 100 parts by mass of the binder resin, and a mass ratio of the content of the compound A to the content of the compound B (compound A/compound B) is from 0.8 to 20:
- where R1A, R1B, R2A and R2B are each independently a halogen atom, an alkyl group, a methoxy group, an amino group, a nitro group, an acetylamido group (—NHCOCH3), a methyl ester group (—COOCH3) or a primary amide group (—CONH2);
- R3 is a halogen atom;
- R4 and R5 are each independently a halogen atom, an alkyl group, a methoxy group, an amino group, a nitro group, an acetylamido group (—NHCOCH3), an acetyl group (—COCH3), a methyl ester group (—COOCH3) or a primary amide group (—CONH2);
- a1 and b1 are positive integers that a sum of the positive integers is 2 or 3;
- a2 and b2 are positive integers that a sum of the positive integers is 2 or 3;
- c is an integer of 1 or more and 3 or less;
- and d and e are each independently 1 or 2,
- where R6 is an alkyl group.
