Abstract (en)
The present invention relates to a composition for the fluorescent whitening of paper comprising a) a bis-triazinylamino stilbene of the formula in which R 1 , R 2 , R 3 and R 4 each, independently, represent -NH 2 , -OC 1 -C 4 alkyl, -Oaryl, -NHC 1 -C 4 alkyl, -N(C 1 -C 4 alkyl) 2 , -N(C 1 -C 4 alkyl)(C 1 -C 4 hydroxyalkyl), -NHC 1 -C 4 hydroxyalkyl, -N(C 1 -C 4 hydroxyalkyl) 2 , or-NHaryl, whereby aryl is phenyl, which may be unsubstituted or substituted by one or two sulphonic acid groups, -COOH, -COOC 1 -C 4 alkyl, -CONH 2 , -CONHC 1 -C 4 alkyl or by -CON(C 1 -C 4 alkyl) 2 , a morpholino, piperidino or pyrrolidino residue, -SC 1 -C 4 alkyl or aryl, or an amino acid or amino acid amide residue from which a hydrogen atom has been abstracted from the amino group and M represents hydrogen, an alkaline or alkaline earth metal, ammonium or ammonium that is mono-, di-, tri- or tetrasubstituted by C 1 -C 4 alkyl or C 2 -C 4 hydroxyalkyl or a distyryl biphenyl fluorescent whitening agent (FWA) of the formula in which R 5 represents hydrogen, chlorine or C 1 -C 4 alkoxy and M is as defined above, or mixtures of (1) and (2), b) water and, optionally, c) one or more auxiliaries, characterized in that the pH of the composition lies within the range of from 10 to 13, size or film press liquors and coating colours containing the composition and use and process for application of the composition to paper.
