Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector
CHARGE-TRANSPORTING INK COMPOSITION
Provided is a charge-transporting ink composition for an upper layer of a quantum dot layer, the composition being configured such that: when used to form an upper layer of a quantum dot (QD) layer (light emission layer), the changes in the flatness of the film formed by inkjet deposition can be suppressed, such changes occurring due to the post-deposition time delay; practical charge-transporting properties can be maintained; and photoluminescence (PL) quenching of the quantum dot (QD) layer in the element obtained is not triggered. The composition contains a charge-transporting material and a solvent, where the solvent is a specific solvent having a Balaban index of 3.3 or lower and a molar refractive index of 65 or lower, and also having a boiling point of 180°C or higher.
