摘要

本研究的目的係比較省產木材之耐光性，以供選擇作為室內裝潢用材之參考。選用測試之木材計有澗葉樹材 8 種及針葉樹材 5 種，將素材以及經由拉卡塗裝之試材置於植物燈下進行耐光性試驗，經過一定的照射時間後，以色差計測量試材表面顏色之變化情形，以色差值(△E*)與明度留存率之大小來評估木材耐光性之好壞。試驗結果得知，所測試的 8 種澗葉樹材中，以臺灣櫸與大葉楠之耐光性最佳，其次為樟樹、木荷與泡桐，再其次為相思樹，而桃花心木與銀合歡的耐光性最差；所測試的5種針葉樹材中，以柳杉之耐光性較佳，其次為紅檜，而巒大衫、鐵杉與雲杉之耐光性最差。

The objective of this study was to investigate the lightfastness of interior decorative paneling made from Taiwan woods. Woods examined in this study included eight hardwood species and five softwood. species. Unprotected panelings and panelings coated with nitrocellulose lacquer were exposed to a plant lamp and their lightfastness was evaluated by comparing color difference and brightness retention.
The results of the lightfastness of woods are summarized as follows.
1. The lightfastness of eight hardwood species in decreasing order is: Taiwan Zelkoza, Large Leaved Machilus＞Camphor Tree, Chinese Guger-Tree, Fortune Paulownia＞Taiwan Acacia＞Mahogany, Hedge Acacia.
2. The lightfastness of five softwood species in decreasing order is: Crytomeria＞ Taiwan Red Cypress＞Luanta Fir, Taiwan Hemlock, Taiwan Spruce.
