Scratch and mar damages can critically impact the aesthetics of polymeric surfaces. Improving scratch and mar visibility resistance of polymers is of big interest for academic and especially industrial arenas. In this paper, we investigate the influence of surface brightness, color and transparency on scratch and mar visibility resistance in polymers. A new psychophysical test based on Multidimensional Scaling (MDS) statistical method was utilized to determine mar visibility resistance onset. It has been found that scratch visibility resistance decreases with greener, lower brightness and higher transparency samples. Preliminary results show that MDS is a powerful tool to disseminate the psychophysical evaluation of mar damage. This research paves the way for a standardized methodology to reliably quantify scratch and mar visibility resistance in polymers.
