Abstract
(EN)
The present invention relates to an ink composition which contains: (a) a charge transport substance; (b) one or more kinds of metal oxide nanoparticles; and (c) a liquid carrier which contains (c-1) a first hydrophilic glycol-based solvent having a boiling point bp1 (°C), (c-2) a second hydrophilic glycol-based solvent having a boiling point bp2 (°C) and (c-3) an organic solvent having a boiling point bp3 (°C), and which satisfies bp1 < bp3 < bp2.
(FR)
La présente invention concerne une composition d'encre qui contient : (a) une substance de transport de charges ; (b) un ou plusieurs types de nanoparticules d'oxyde métallique ; et (c) un véhicule liquide qui contient (c-1) un premier solvant à base de glycol hydrophile ayant un point d'ébullition bp1 (°C), (c-2) un second solvant à base de glycol hydrophile ayant un point d'ébullition bp2 (°C) et (c-3) un solvant organique ayant un point d'ébullition bp3 (°C), et qui satisfait à la relation bp1 < bp3 < bp2.
(JA)
