螢光照射による木質材料の退色

This paper deals with the effects of the exposure(100 hours) by fluorescent lights(15000 lux) to eleven wooden materials. Eleven wooden materials are 4 amino alkyd resin coating materials and 7 non-coating materials.
The fading occured between before and after exposure and is expressed by the color difference．And the color of eleven wooden materials are evaluated by the C I E system.
The results obtained are as follows :
(1) The chroma and the hue of eleven wooden materials are raised by the amino alkyd resin coating.
(2) The change of luminosity by the fading is variable，but the degree of the change is larger than that of the chroma and the hue.
(3) Approximately the hue changes to the extent of yellow-orange-red by the fading.
(4) The fading of the amino alkyd resin coating material and non-coating matenal is different.
