A compound having general formula (I) in which the following designations are used: R1 = one to four substituents from the series -Z, -OZ, -NZ2, -NH2,- NH2, -CN, -CF3, where Z = C1-C5 alkyl, phenyl, pyridyl, benzyl. R2 = -H, -Z, -CH2Z. R3, R4, R5 = -NH2, NHZ, -NZ2, -OZ, -Z, -H. R6 = -H, -Z, -OZ, -CN, -NO2. HAr = two- or three-nucleus heteroaromatic compounds with 1 or 2 N-atoms in accordance with the following structure formulas (II). The compounds offer the advantage that their migration in plastic materials used for spectacle glasses is reduced, so that no softening effect occurs which would be disadvantageous in the case of coating glasses of that type with for example anti-reflection layers.
