Figure 2.

Photodegradation kinetics of MBT in HAVOH‐based coatings under a) UV irradiation and b) artificial lighting. Solid lines are guides for the eye. The inset in (a) shows representative UV/Vis spectra of HAVOH‐MBT (solid line) and HAVOH‐LDH/MBT (dashed line) coatings having the same thickness and total MBT amount. c) Photodegradation kinetics of MBT in HAVOH‐based coatings containing commercial UV absorbers/light stabilizers and HAVOH‐LDH/MBT coatings. The average transmittance of the coatings is reported in the inset.
