Abstract:
The disclosure discloses a polyacrylate dispersant, a pigment dispersion, a color photoresist, a color filter substrate and a display device. The polyacrylate dispersant of the disclosure is a polyhedral oligomeric silsesquioxane-modified polyacrylate dispersant prepared by an esterification reaction of a polyacrylate dispersant and polyhedral oligomeric silsesquioxane. Due to a steric hindrance effect of the structure of polyhedral oligomeric silsesquioxane, the polyacrylate dispersant of the disclosure may significantly improve the stability of pigment dispersion when used for dispersing pigment powder. A color photoresist prepared based on the pigment dispersion has a prominent heat resistance, an excellent resolution and a surface smoothness, as well as a low dielectric constant.
Abstract:
The general inventive concepts relate to an alkali soluble binder which is obtained by copolymerizing main polymerization monomer(s) and functional polymerization monomer, wherein said main polymerization monomer is selected from the group consisting of (meth)acrylic acid and esters thereof, and said functional polymer monomer comprises (meth)acrylic acid C14-C22 alkyl ester and C4-C6 alkenyl anhydride or dianhydride. The general inventive concepts further relate to a photosensitive binder composition and a process for producing the alkali soluble binder and a process for producing the photosensitive binder composition.
Abstract:
An alkaline soluble resin, a process for preparing the same, and a photoresist composition containing the same. The alkaline soluble resin is a polyether chain-containing acrylate alkaline soluble resin. A photoresist composition comprising said alkaline soluble resin can reduce the slope angle of the film layer and prevent gaps which cause light leakage from forming in the junction between the colored film layer and the black matrix. Moreover, the coating and the rubbing effect of the orientation layer can be improved.
