• -dimethylethyl)amino)anthraquinone (12), as well as 1-((1,3-dimethacryloxy-2-methylpropan-2-yl)amino)anthraquinone (15) were obtained. By mixing of these brilliant dyes in different ratios and concentrations, a broad color spectrum can be generated. After methacrylation, the monomeric dyes can be covalently

• . Keywords: anthraquinone; monomeric dyes; red; green; blue dyes; polymer; Introduction Anthraquinone and its derivatives bearing hydroxy and amino moieties are of remarkable importance in pharmacological, biochemical and dye industries [1][2]. They have been described as important compounds for decades [3

• hydrogen atoms in the α-position also protects the amino group from further reactions. In the cases of the green and blue monomeric dyes this effect was achieved by introducing a benzene ring in the α-position [25]. 1,4-Dichloroanthraquinone was treated with 1,1-dimethyl-2-hydroxyethylamine to form two
