Abstract:
A composition having excellent dischargeability by an ink jet method and reduced clogging of an ink jet apparatus is provided. The composition contains a fluorinated alcohol A represented by the formula (1) and having a boiling point of 50° C. or more and less than 150° C., a fluorinated alcohol B represented by the formula (1) and having a boiling point of 150° C. or more and less than 300° C., and a charge transportable compound, in which the ratio rate of the fluorinated alcohol B with respect to 100 parts by mass of the sum of the fluorinated alcohol A and the fluorinated alcohol B is 10 parts by mass to 90 parts by mass: CnFH2nF+1-mFFnFOH (1) In formula (1), nF is an integer of 1 to 12 and mF is an integer of 1 to 25, provided that 2nF+1≥mF.
