PROBLEM TO BE SOLVED: To provide a composition that achieves both dispersion stability and image properties and further forms a uniform film structure on a medium. SOLUTION: The composition comprises at least an amphiphilic block polymer compound having a hydrophobic block segment containing a unit structure represented by general formula (1) or (2) (wherein R<SB>1</SB>to R<SB>9</SB>and R<SB>11</SB>to R<SB>19</SB>are each independently a hydrogen atom or a 1-4C linear or branched organic group) and a hydrophilic block segment, and an aqueous solvent.
