どから、環境汚染上にも問題がある。 Conventionally, inkjet recording inks include water-based inks with water-soluble dyes dissolved in them, and oil-based inks with oil-soluble dyes dissolved in them.While water-based inks have advantages such as conductivity, low viscosity, and nonflammability, There is a drawback that the water resistance of the image is insufficient. Oil-based inks have sufficient water resistance for images, but the specific conductivity of the ink is high, and adding electrolyte to lower this will often cause nozzle clogging, and the viscosity is relatively high, so it is difficult to use oil-based inks. There is also a risk of nozzle clogging. In addition, because it is flammable, it also poses a problem in terms of environmental pollution.
