Peptides have been identified that bind with high affinity to common ink pigments and to various print media, including paper and fabrics. These peptides were used to prepare diblock and triblock dispersants for coating applications, including ink jet printing, and diblock polymers for treating paper and fabrics. The diblock dispersants consist of a pigment-binding peptide coupled to a hydrophilic linker, a pigment-binding peptide coupled to a print medium-binding peptide or a print medium-binding peptide coupled to a hydrophobic linker. The diblock polymers consist of a print medium-binding peptide coupled to a hydrophilic linker or a benefit agent. The triblock dispersants consist of a pigment-binding peptide coupled to a hydrophilic linker, which is coupled to a print medium-binding peptide. |
