“…In this paper, we studied effect of dispersant in CFPR on CCD. As shown in figure 2(a), dispersant in CFPR prevents aggregation between colorant particles [9,10]. Figure 2 (b) and (c) represent schematic and chemical structure of dispersant.…”

“…[13][14][15] Polymeric pigment dispersants are copolymers with pigment affinic "anchoring group" and soluble polymeric chains "stabilizing group". [16][17][18][19] In the case of polymeric dispersants, however, dispersion stabilization is generally provided by two major mechanisms: electrostatic and steric stabilization. Electrostatic stabilization in organic system involves adsorbed ions building up a charged layer around the pigment, preventing aggregation by electrostatic repulsion.…”

The dispersion of pigment particles is important because it is capable of increasing the color strength, contrast, and transmittance of color-LCD products. Pigment dispersion properties are very important factors for the quality of LCD color filters. The chemical structure of polymeric dispersants for pigment is important to improve dispersion stability and prevent aggregation or flocculation of pigment in organic or aqueous systems. Polymeric dispersants should contain both anchoring group that interacts with pigment surface and stabilizing group that provides steric stabilization. Moreover, the molecular weight and composition of block copolymer have the an effect on pigment dispersion. In this study, adequate dispersants, block copolymers containing (2-dimethylamino)ethyl methacrylate as anchoring group and oligo(ethylene oxide)methyl ether methacrylate as a stabilizing group were designed and synthesized by atom transfer radical polymerization in order to prepare well-defined structure, molecular weight and composition.

“…The compound itself and its derivatives are widely employed as feedstocks for manufacturing a number of industrial chemicals, primarily pesticides [1], polymer backbones [2,3] as well as plasticisers [4]. As an active component in the pigments production, PI is derivatised to make coloured units in the polymer dyes [5,6]. Tetrahydrophthalimide (THPI) constitutes an important derivative of PI, with the benzene ring replaced by a cyclohexene ring (Fig.…”
