摘要: The present invention relates to electroluminescent devices that comprise organic layers that contain triazole compounds of the formula (I), or formula (II). The compounds are suitable components of, for example, blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in, for example, mobile phones, televisions and personal computer screens.

摘要: A whitening pigment comprising the reaction product of (a) a melamine-formaldehyde and/or a melamine-urea poly-condensation product and (b) a water-soluble fluorescent whitening agent of the formula (1), wherein each of the two R1 groups, independent of the other, represents a C1-C6alkyl or C1-C4alkyl-O—C1-C4alkyl residue, which is substituted by one or two —CONH2, —CONHC1-C4alkyl, —COOH, —SO2NH2, —SO2NHC1-C4alkyl or —NH2 groups, each of the two R2 groups, independent of the other, represents hydrogen, C1-C4alkyl, C2-C4hydroxyalkyl or C1-C4alkoxyC1-C4alkyl, or R1 and R2 together with the nitrogen atom complete a piperazine ring, each of the two X1 groups, independently, represent —OH, —OC1-C4alkyl, —Oaryl or the group —NR3R4, wherein R3 and R4 each, independently, represent hydrogen, C1-C4alkyl, C2-C4hydroxyalky, C1-C4alkoxyC1-C4alkyl, a phenyl, phenyl mono- or disulphonic acid residue or, R3 and R4, together with the nitrogen atom to which they are attached, complete a morpholino, piperidino or pyrrolidino ring or, alternatively, X1 represents an amino acid residue from which a hydrogen atom has been abstracted from the amino group and M is hydrogen, an alkaline or alkaline earth metal ion, ammonium, mono- di-, tri- or tetra-substituted C1-C4alkylammonium or C2-C4hydroxyalkylammonium or mixtures thereof, a process for preparation of the pigments and the use thereof for the fluorescent whitening of paper.
