Light resistant colorant and composition containing the same

A light resistant colorant obtained by coupling a colorant having at least one functional group selected from the group consisting of amino groups, hydroxyl groups caroxyl groups, and sulfonic acid groups with a compound represented by Formula 2:

• wherein R1 is selected from the group consisting of a substituted or an unsubstituted alkylene of 1–20 carbon atoms and a substituted or an unsubstituted heteroalkylene of 1–20 carbon atoms;
• R2, R3 and R4 are independently selected from the group consisting of a hydrogen, a substituted or an unsubstituted alkyl of 1–4 carbon atoms, and a substituted or an unsubstituted heteroalkyl of 1–4 carbon atoms;
• R5 is selected from the group consisting of a hydrogen, an alkyl of 1–20 carbon atoms, a heteroalkyl of 1–20 carbon atoms, an aryl of 6–20 carbon atoms, and a heteroaryl of 6–20 carbon atoms;
• and X is selected from the group consisting of a halogen, a hydroxyl, an amino, carboxylic acid or a salt thereof, sulfonic acid or a salt thereof, and phosphoric acid or a salt thereof.
