“…And emulsion polymerization is getting the favor of researchers in preparing composite particles for the merits of uniform dispersion, small particle size, and narrow size distribution, and so on. However, the size of composite latex particles obtained by emulsion polymerization is nanoscaled, [10,11] which cannot meet the requirement of a suitable micrometer size of toners below 15 μm during the actual printing process. So, the aggregation process for latex particles is needed to acquire microparticles.…”

“…Particle aggregation process is of fundamental interest in colloid science, medicine, biology, and immunology, which is also widely applied in food processing, paper making, mining, water and wastewater treatment fields. [5,10] According to the aggregation mechanism, the aggregation of particles can be divided into the following four kinds: electronic double-layer compression, [12] charge, [13] adsorption bridging, [14] and sweep flocculation. [15] In the past few years, the techniques of particle aggregation have been explored extensively.…”

In this paper, the styrene–acrylic resin‐encapsulated organic pigment composite nanoparticles were synthesized by mini‐emulsion polymerization first, and then the aggregated microparticles used for color toner were prepared via the emulsion aggregation method. Transmission electron microscopy, dynamic light scattering, and zeta potential analysis manifest that when the emulsifier dosage was 5 wt% of the monomer, the composite nanoparticles owned clearly core‐shell structure, uniform size, and appropriate zeta potential, which was conducive to the subsequent aggregation. The evolution of aggregated particle size and morphology under different stirring rates, coagulant concentrations, and temperatures was investigated by mastersizer and scanning electron microscopy. The result shows that when the stirring rate was 1,000 rpm, coagulant concentration was 0.2 mol/L, and the curing temperature was 65°C, aggregated particles with suitable size, narrow size distribution, and regular shape could be obtained. The reshaping of aggregated particles can further improve their morphology. When the reshaping temperature was 75°C, the product particles owned perfect spherical shape, and there were almost no cracks and pores on the surface of the particles. This synthesis strategy is believed to provide a guide for the fabrication of composite microparticles with controllable particle size and morphology.

“…Organic pigments have excellent color expressiveness, photosensitivity, tinting power, and vivid color properties. Thus, they are widely used in fabric printing and dyeing, inkjet printing, paint preparation, and many other applications [1][2][3]. On the other hand, the drawbacks of organic pigments, such as their poor dispersion, weak weathering resistance, poor stability, uneven particle size, and easy agglomeration properties, limit the application of organic pigments in many fields such as waterborne coatings [4,5].…”

Phthalocyanine pigments have many problems in waterborne coating applications because of their low polarity, poor dispersion in water, and easy agglomeration properties. In order to solve these problems, the phthalocyanine pigments were encapsulated with a copolymer of methyl methacrylate (MMA) and butyl acrylate (BA) by a mini-emulsion polymerization method. The pigments are effectively dispersed in water and have good compatibility with the resin. Concerning the bacterial reproduction and growth problem for the waterborne system, the resin-encapsulated phthalocyanine pigments were further grafted with antibacterial polymer poly(N-(2-hydroxyethyl) acrylamide) (PHEAA) on its surface using the photoemulsion polymerization technique. Comprehensive properties, including centrifugal stability and chromaticity change, were studied. The polymer encapsulation improved the centrifugal stability of the pigment. The thermogravimetric results showed that the residual mass of C.I. Pigment Green 7 (52.30%) was higher than that of C.I. Pigment Blue 15:3 (30.06%), and the sublimation fastness of PG7 was higher. The TEM results revealed that the shape of the PG7 after encapsulation and grafting was more regular than that of PB15:3. The L* of the pigment decreased after encapsulation but then increased after further grafting. The phthalocyanine pigment composite latex had good antibacterial properties after the grafting of PHEAA.

“…Pigment printing has numerous advantages in terms of photosensitivity and transparency, and its process is more ecofriendly as compared with that of traditional dye coloring. [1][2][3][4] Commonly, organic pigments attach to the fabric surface in the form of a pigment/polymer blended lm. [5][6][7] However, these pigment particles usually tend to agglomerate with each other in the polymer blend matrix, resulting in poor printing properties.…”
