Zusammenfassung:PROBLEM TO BE SOLVED: To reduce cost and environmental load such as wastewater treatment by easily realizing regeneration of an uncured ultraviolet curing resin colored by being mixed with another material, particularly an organic compound. SOLUTION: The colored and uncured ultraviolet resin is decolored and regenerated by irradiation with light of wavelength in the vicinity of the maximum absorption wave length of the coloring material to contribute to cost reduction and environmental protection.
