All are based on preparations which contain caffeic acid (i.e. coffee or tea) and a pH modifier, most often sodium carbonate.〔〔(Formulas )〕 The chemistry of caffenol developers is based on the action of the reducing agent caffeic acid (which is chemically unrelated to caffeine).〔 ==History== The Technical Photographic Chemistry Class at RIT in 1995 led by Dr. Scott Williams developed a method of developing photographic film using standard household items. The tested mixtures of tea and coffee combined with agents to balance the pH and successfully made printable images for exposed film.〔(A use for that last cup of coffee: film and paper development )〕 At the time they did not call it "Caffenol", but the methods they developed later became commonly called Caffenol. 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「Caffenol」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.
