Description

201024329 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a dispersant', particularly to a polymeric dispersant. [Prior Art] Organic pigments are different from dyes and are insoluble solid particles. They are dispersed in different solvents or resins and then applied. They have better thermal stability, durability and UV resistance. It can improve the color vividness of the color, etc., and can protect the surface of the coated system. It can be seen from the above that the pigment is superior to the dye in all aspects, but because the pigment particles are easy to aggregate during the production process, and the particle size is large, the pigment particles are too large, resulting in a decrease in the amount of the pigment, color saturation, color saturation and stability. dispersion. Therefore, the dispersant is further used to promote fine dispersion, nanocrystallization, and high stability of the pigment particles. At present, the color dispersion of liquid crystal display (LCD) color filters requires dispersion and stability, and the light transmittance is high, and the color light and resolution are good. However, the key is the dispersant, and the dispersant must For the dispersion system design, the anchoring end can have a strong adsorption effect on the pigment'/the solvation end should have an appropriate smelting effect. Many of the past polymeric dispersants used random copolymers (rad〇in c〇p〇lymer), but these are relatively ineffective materials. U.S. Patent No. 5,852,123 discloses a dispersant comprising a graft copolymer having a backbone of a polymer and a megamonomer side chain grafted onto the backbone and linking the megamons or polar groups on the backbone, It is designed to adsorb on the surface of the pigment particles and to connect the copolymer dispersant to the surface of the pigment. However, such a dispersant 201024329 causes the pigment particles to be too close together to cause aggravation of the stability and rheology of the pigment dispersion and the coating, and to reduce the strength of the color. Based on the above, a new dispersant is designed to optimize the dispersion of the pigment, which is the focus of the dispersant technology. SUMMARY OF THE INVENTION The present invention provides a dispersant which is composed of a compound having a terminal amine group (for example, poly(oxyalkylene) diamine) or poly(oxyalkylene) triamine and A polymeric dispersant prepared by the reaction of a diisocyanate (a compound having two isocyanate functional groups), which can be used as a dispersing agent or a stabilizer to form a stable pigment composition (dispersion liquid) Or a color paste. The dispersant further comprises a urea-based (Urea) segment which can form a hydrogen bond with a functional group modified by the surface of the pigment, and is attached so that the dispersant coats the outer layer of the pigment, and further, the dispersant comprises Oil-soluble segments (such as oxypropylene segments) can utilize the lipophilic nature of the segment to dissolve the dispersant in the acrylic monomer solvent and stabilize the steric barrier effect of the dispersing agent by melting the chain ends. The pigment particles are dispersed in the acrylic monomer to avoid pigment aggregation, the dispersant can be added to a high concentration, and the resulting dispersion can still be maintained at a low viscosity.
