Abstract
Official abstract text for this publication.
The present invention provides a toner excellent in both saturation and light resistance. The toner includes toner particles containing a binder resin and a colorant. The colorant is a pyridoneazo compound having a specific structure.
First claim
Opening claim text (preview).
1 . A toner comprising: a binder resin; and a colorant, wherein the colorant is a coloring compound represented by Formula (1): wherein R 1 and R 2 each independently represent an alkyl group, an aryl group, or an amino group; R 3 and R 4 each independently represent a hydrogen atom, a cyano group, a carbamoyl group, a carboxylic acid ester group, or a carboxylic acid amido group; m and n each independently represent an integer of 0 to 4; A 1 , A 2 , B 1 when m is 1 to 4, and B 2 when n is 1 to 4 each independently represent a carboxylic acid ester group, a sulfonic acid ester group, a carboxylic acid amido group, or a sulfonic acid amido group; and L represents a straight chain alkylene group having 1 to 12 carbon atoms, a branched alkylene group having 1 to 12 carbon atoms, or a phenylene group. 2 . The toner according to claim 1 , wherein in Formula (1), A 1 , A 2 , B 1 when m is 1 to 4, and B 2 when n is 1 to 4 each independently represent a sulfonic acid ester group, a carboxylic acid amido group, or a sulfonic acid amido group; and L represents a phenylene group. 3 . The toner according to claim 1 , wherein in Formula (1), A 1 , A 2 , B 1 when m is 1 to 4, and B 2 when n is 1 to 4 each independently represent a carboxylic acid amido group; and L represents a straight chain alkylene group having 1 to 12 carbon atoms or a branched alkylene group having 1 to 12 carbon atoms. 4 . The toner according to claim 1 , wherein in Formula (1), at least one of A 1 and A 2 represents a carboxylic acid dialkylamido group. 5 . The toner according to claim 1 , wherein in Formula (1), at least one of A 1 and A 2 represents a carboxylic acid di(2-ethylhexyl)amido group. 6 . The toner according to claim 1 , wherein in Formula (1), L represents an ethylene group. 7 . The toner according to claim 1 , wherein in Formula (1), the partial structures on both sides of L have the same structure. 8 . The toner according to claim 1 , produced by suspension polymerization or emulsion aggregation.
