Lacquer is known to be vulnerable to UV-Rays generally. So in this study we tried to confirm the durability of the lacquer against UV deterioration by using Sunscreen and UV Stabilizer. Based on KS M ISO 4892-3, aspect of UV deterioration of lacquer film with sunscreen and lacquer film coated with UV-stabilizer was observed for up to 1080 hours and the deterioration patterns were also observed at regular intervals. To evaluate the deterioration degree, gloss, chromaticity, surface observation, microscope and FT-IR analysis were performed. As a result of the analysis, sunscreen mixed lacquer maintained the gloss longer than the UV-stabilizer coated lacquer, and the color change was less. It was also confirmed that the sunscreen mixed lacquer has the longest durability against deterioration in observing surface and microscope. Through FT-IR analysis, it was verified that the sunscreen mixed lacquer was more similar in chemical structure to pure lacquer than UV-stabilizer coated lacquer. For the degradation rate, the degradation progressed less than that of the control group. Summarizing the results of these studies, it is judged that the lacquer has the best durability against light deterioration when a 2% concentration of sunscreen was mixed lacquer.
