Zusammenfassung:	The present invention relates to an anthrapyridone compound represented by the following Formula (1) [KA 1] (see formula 1) (wherein, R represents a hydrogen atom, an alkyl group, a hydroxy lower alkyl group, a cyclohexyl group, a mono- or dialkylaminoalkyl group or a cyano lower alkyl group, X represents a cross linking group, Y represents a phenoxy group having 1 or 2 carboxyl groups) in free acid form and a magenta ink composition comprising the same, and provides magenta coloring matter and a magenta ink composition which have hue with high vividness suitable for inkjet recording, gives good fastness to a recorded article and are excellent in storage stability. L'invention porte sur un composé d'anthrapyridone de formule (I) sous la forme d'un acide libre, et sur une encre magenta contenant ledit composé. Dans la formule (I) R représente un groupe hydrogène, un groupe alkyle, un groupe hydroxy alkyle inférieur, un groupe mono ou dialkylaminoalkyle ou un groupe cyano alkyle inférieur; X représente un groupe réticulant; et Y représente un groupe phénoxy à un ou deux groupes carboxyle. Le colorant magenta et l'encre magenta présentent une tonalité de haute définition convenant aux jets d'encre, une excellente stabilité au stockage et une grande solidité des impressions.
