From: Investigating the effect of artists’ paint formulation on degradation rates of TiO2-based oil paints
Contour plots for a initial gloss, b calculated relative gloss decay at 500 J/cm2, c state of chalking at I6 and d state of chalking at I8 in relation to the formulations of Experiment III. All mixtures contain a fixed volume fraction (0.14) of UA. Mind that in figure a red indicates a high gloss while in figure b, c red indicates high degradation and thus a low gloss
