Zusammenfassung:	To provide methods of using novel merocyanine derivatives comprising specific polar groups consisting of hydroxyl- and ether-functionalities for protecting household products from photolytic and oxidative degradation.SOLUTION: For example, an embodiment uses as an additive the compound of formula (101) obtained in a process in which bis-(2-methoxyethyl)amine is reacted with 1,1,3,3-tetramethoxypropane in acetic acid, concentrated and treated with ethyl cyanoacetate in the presence of an organic base and a solvent.SELECTED DRAWING: None 【課題】家庭用製品を光分解及び酸化的分解から保護するためのヒドロキシル-及びエーテル-官能基からなる特定の極性基を含む新規なメロシアニン誘導体の使用方法の提供。【解決手段】例えば、ビス−（２−メトキシエチル）アミンを酢酸中で、１，１，３，３−テトラメトキシプロパンと反応させ、濃縮し、有機塩基及び溶媒の存在下、エチルシアノアセタートで処理することで得られる式（１０１）の化合物を添加剤として使用する。【選択図】なし
