1. the dye compositions that comprises at least a chromophoric group and polymer nano granules (PNP),Wherein said PNP comprises at least a polyenoid and belongs to unsaturated monomer as polymerized unit;

  • Wherein said PNP has mean diameter, 0-700mgKOH/gPNP solid acid number, the amine value of 0-250, the 0-250mgKOH/gPNP solid hydroxyl value of 1-25nm, and containing at least 2% polarizable group, this polarizable group is meant the functional group of moment of dipole greater than 1.10 debye unit(D)s;

    AndDescribed composition contains the PNP coagulant aids, its amount is the 1-50wt% of PNP weight, described PNP coagulant aids is selected from the compound that contains at least one hydrophilic segment and at least two hydrophobic segments, the Mn of wherein said hydrophilic segment is greater than 2,000, and the hydrophobicity of described hydrophobic segment is enough to form nonspecific hydrophobic association effect.
