Abstract
The 1-aminoanthraquinone glycidyl ester (GEAA) obtained by reaction of N-alkylation of 1-aminoanthraquinone with epichlorohydrin was used in the synthesis of a structurally colored epoxy resin by co-polycondensation with with diphenylolpropane and epichlorohydrin. Structurally colored epoxy resin is a viscous liquid with a molecular weight of 400–1000, colored orange and soluble in organic solvents. The optimal amount of GEAA (from 0.1 to 0.5% wt.) is established, which provides high color intensity (molar extinction coeffi cient 0.16–1.38·104).

Summary
Реакцией N-алкилирования 1-аминоантрахинона эпихлоргидрином получен глицидиловый эфир 1-аминоантрахинона (ГЭАА), который использовали при синтезе структурноокрашенной эпоксидной смолы путем совместной поликонденсации с дифенилолпропаном и эпихлоргидрином. Установлено оптимальное количество ГЭАА (от 0,1 до 0,5% мас.), обеспечивающее высокую интенсивность цвета (молярный коэффициент экстинкции 0,16 1,38·104). Ключевые слова: 1-аминоантрахинон, глицидиловый эфир 1-аминоантрахинона, структурноокрашенная эпоксидная смола, спектры поглощения, молярный коэффициент экстинкции The 1-aminoanthraquinone glycidyl ester (GEAA) obtained by reaction of N-alkylation of 1-aminoanthraquinone with epichlorohydrin was used in the synthesis of a structurally colored epoxy resin by co-polycondensation with with diphenylolpropane and epichlorohydrin.
