Coloring composition, ink for ink jet, and ink jet recording method

A coloring composition comprising:

• coloring particulates containing an oil-soluble polymer and an oil-soluble dye, the dye being represented by at least one of following formulae (I), (II), (III), (IV), seid coloring particulates being dispersed in a water-based medium:
• 32 33 34 35
• formulae (I) through (IV)
• wherein, in formulae (I), (II), (III) and (IV), R1, R2, R3 and R4 each represent a hydrogen atom or a non-metallic atomic group;
• X represents —OH or NR5R6;
• R5 and R6 each represent a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group;
• R7, R8 and R9 each represent a hydrogen atom or a non-metallic atomic group;
• at least one of R1 and R2, or R2 and R5, or R5 and R6, or R6 and R3, or R3 and R4 may form a ring structure;
• and R7 and R8 may bind together to form a ring structure.

An ink jet recording method comprising the steps of:

• (a) preparing an ink for an ink jet, containing a coloring composition in which coloring particulates, containing an oil-soluble polymer and an oil-soluble dye represented by at least one of following formulae (I), (II), (III), (IV), are dispersed in a water-based medium:
• 36
• formulae (I) through (IV)
• wherein, in formulae (I), (II), (III) and (IV), R1, R2, R3 and R4 each represent a hydrogen atom or a non-metallic atomic group;
• X represents —OH or NR5R6;
• R5 and R6 each represent a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group;
• R7, R8 and R9 each represent a hydrogen atom or a non-metallic atomic group;
• at least one of R1 and R2, or R2 and R5, or R5 and R6, or R6 and R3, or R3 and R4 may form a ring structure;
• and R7 and R8 may bind together to form a ring structure;
• and
• (b) using the ink for recording in an ink-jet printing device.
