Our society, which has achieved high accumulation and high efficiency, has been forced to change by the new coronavirus COVID-19. The transmission route of COVID-19 is not only from human to human, but also object to human because of the survival period of the virus on objects. So, it is common to rub and clean the surface of object with surfactants or alcohol in various situations in our lives. On the other hand, water-based printing ink is being used in many fields from the viewpoint of safety and security of printed matter and reduction of global environmental load. However, some conventional printed matters don't have sufficient durability and suitability to wiping with alcohol. Therefore, in this paper, a new polyester ink which have enough resistance to rubbing 80% ethanol water have been developed to prevent infection from object to human effectively.
