翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Lightfastness ： ウィキペディア英語版 Lightfastness Lightfastness is a property of a pigment or paint that describes how resistant to fading it is when exposed to light. Light striking a painted surface can alter or break the chemical bonds of the pigment, causing the colors to bleach or change, in a process known as photodegradation. Materials that resist this effect are said to be lightfast. ==Standards== Some organizations publish standards for rating the lightfastness of pigments and materials. Testing is typically done by controlled exposure to sunlight, or to artificial light generated by a xenon arc lamp. Watercolors, inks, pastels, and colored pencils are particularly susceptible to fading over time, so choosing lightfast pigments is especially important in these media.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lightfastness」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
