Résumé
Fluorescent paints have been used in artwork from the mid-twentieth century onwards, being particularly prominent in the pop art movement. In additional to their bright colours and luminosity, these are also known to be fugitive. Conservators may use glazing materials to protect the artwork so as to avoid applying anything directly to the acrylic paint surface. Museum environments usually exclude ultraviolet light, so the artowrks are subjected to teh visible part of the electronmagnetic spectrum. Besides protection from ultraviolet light, can glazing offer protection from light damage in the visible spectrum. The goal of this research was to evaluate fluorescent acrylic paints from the Tri-Art Company as well as three different glazing options currently used in musems (Sheffield Bayer Makrolon, Plexiglas MC, TruVue Optium Museum). The aim was to determine how the paints maintin their colour and vibrancy with overlaying glazing. Sampes were subjected to three types of aging: natural light aging, exterme light exposure in a Q-Sun Xenon Arc test chamber at two time intervals, and micro-fading. To determine the efficacy of the glazing, the following tests were conducted: pyrolysis gas chromatography mass spectrometry (Py/GC-MS), Fourier transform infrared (FTIR) spectroscopy, colorimetry measurements, and ultraviolet-visible solid-state absorption spectrometry. The results indicate a quicker propensity for fading to occur in samples with glazing than in samples without. This was true wherever ultraviolet was excluded. The increase in fading rates was unexpected, but demonstrates a necessity for a closer look at the effects of glazing in museum environments.
