摘要： There are provided a printed film having an increased wet rub resistance and a printing method, an ink set, and a printing apparatus that can increase the wet rub resistance.
The printed film is formed on the surface of a non-water-absorbent or slightly water-absorbent printing medium and contains an organic solvent. The printed film satisfies the following relationship (A): 5≤IA/IMAX≤10 (A). In the relationship, IMAX is the maximum intensity of the secondary ions derived from the organic solvent, measured in the thickness direction from the uppermost surface of the printed film by time-of-flight secondary ion mass spectrometry (TOF-SIMS); and IA is the average intensity of the secondary ions derived from the organic solvent measured in the thickness direction from the uppermost surface of the printed film by time-of-flight secondary ion mass spectrometry (TOF-SIMS) in a period between 0.05×TMAX and 0.50×TMAX after the start of the measurement, wherein TMAX represents the flight time of the secondary ions when the intensity of the secondary ions reaches Imax.
