Coloring compositions comprising peptide-based dispersants and/or binders are provided. The compositions are particularly useful for the coloring or dyeing of substrates such as paper and textile fabrics. The peptide-based dispersant and/or binder compositions are distinguished by the presence of at least one positively charged terminal amino acid on the peptide portion of the composition which enhances binding to the substrate.
L'invention concerne des compositions colorantes comprenant des dispersants et/ou des liants à base de peptides. Ces compositions sont particulièrement utiles pour colorer ou pour teindre des substrats, notamment du papier et des tissus textiles. Les compositions de dispersants et/ou liants à base de peptides de l'invention se distinguent par la présence d'au moins un acide aminé terminal positivement chargé situé sur la partie peptidique de la composition, ce qui augmente le degré de liaison au substrat.
