Abstract
This work reports on the colour changes in wood surfaces, namely from the species European pine, fir, Bosnian pine, chestnut and cherry, which have been modified by a new nanoparticulate treatment. Colour values (CIE L*, a*, b*) for both control and treated wood samples have been studied for each of the five different species. The results have shown a certain effectiveness of the anti-UV surface treatment used, while lower effects were due to ultraviolet light induced photodecolouration. The largest improvements against discolouration were observed with cherry wood. It was observed that anti- UV compound applied on chestnut was particularly less effective (AL= -4.64) in respect to other species. It appears that the yellowness show systematic trends with anti-UV treated samples. However, the UV irridation appears to change surface yellowness of coniferous species more than hardwood species. The anti-UV treated hardwood surfaces (chestnut and cherry) yielded higher gloss than the anti-UV treated softwoods (pine and fir).
