-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 monomericdyes can be covalently

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 monomericdyes 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
