Macromolecular colorants are different from traditional color essences and traditional color pastes. They are products between color essences and color pastes. Their characteristics are more stable, more durable, and brighter than color essences. Compared with color pastes, they have better compatibility with the main resin, more stable coatings, and simpler formulas.

Introduction

Macromolecular colorants are new colorant products independently developed and produced by a certain company. Unlike traditional inorganic and organic small molecule coloring additives, macromolecular colorants use a reactive method to connect chromophores to macromolecular chains. At the same time, the macromolecular colorant materials obtained by water-based treatment have both the light absorption properties of chromophores and the stability and safety of macromolecular materials. The covering power of macromolecular colorants is between color essences and color pastes. They are semi-transparent and semi-covering coloring products. The chromophores can be dispersed at the molecular level. The products have strong coloring power, bright colors, high gloss, no color migration and precipitation, and no color agglomeration. It can perfectly solve the contradiction between poor color essence performance and poor color paste permeability. It has excellent compatibility with other resins. When mixed, there will be no color agglomeration and no particles. It is very uniform and does not require external dispersants. The product is a low-viscosity flowing liquid with very good storage stability. Unlike the traditional pigment grinding and dispersion color paste system, this series of products does not have particles with a particle size greater than 100nm, and is more suitable for small-caliber spray gun spraying systems. It can be used in coatings, synthetic leather, plastics, inks, cosmetics, daily chemicals, biological testing, children's toys and other fields.

Advantages of macromolecule colorants

Core technology

Macromolecular colorants are colored water-based polymer products obtained by copolymerizing polymers and chromophores through chemical reactions. Due to the good compatibility of chromophores and water-based polymers, there will be no problems such as uneven color distribution during the precipitation of pigments during storage, poor light fastness and brushing fastness of the product, which can greatly improve the storage stability of the composite emulsion, and the migration resistance and light fastness of the dye have also been greatly improved.
