The present invention relates to a chemical toner composition and a method for preparing the same. The chemical toner composition includes: a resin emulsion; a pigment dispersion; a wax dispersion; and a dispersible polymer coagulant, wherein the dispersible polymer coagulant is a copolymer comprising unsaturated ester monomers and amino-containing monomers. Accordingly, the present invention uses a novel dispersible polymer coagulant to prepare uniform toner particles with excellent roundness and improved flowability and to reduce moisture absorption.

Chemical toner composition and method for preparing the same

Disclosed are a biomass chemical toner composition and a method for manufacturing the same. First, a biomass resin is mixed with a first hydrophobic resin to form organic particles. The organic particles, a second hydrophobic resin, and a pigment are mixed by emulsion aggregation to form cores. Subsequently, a third hydrophobic resin is formed on the surface of the cores, and the third hydrophobic resin is further heated and coalesced to form a continuous structure encapsulating the cores. Accordingly, the biomass chemical toner obtained from the described method has good anti-humidity, good charge stability, and low fusing temperature.

Biomass chemical toner composition and method for manufacturing the same

A high optical contrast pigment and colorful photosensitive composition employing the same are disclosed. The composition comprises a solvent, an alkali-soluble resin, reactive monomer, and a modified pigment which has low crystallization. The low crystallization degree means that the grain size variation R is not more 80%, wherein the grain size variation R is represented by a formula R=G1/G0&#xd7;100%, G0 is the original grain size, and G1 is the grain size after modification.

A photosensitive composition and a color paste for making the photosensitive composition. The photosensitive resin composition comprises a photosensitive resin system; a pigment; a photo-reactive amphipathic molecule; and a solvent. The color paste for making the photosensitive composition comprises the pigment and the photo-reactive amphipathic molecule.

Photosensitive composition and color paste

An alkali-soluble resin having a polyaromatic group and a photosensitive composition comprising the alkali-soluble resin. The alkali-soluble resin comprises the following recurring units: wherein each of R, R, and R, independently, is H or CH; Ris a substituted or unsubstituted polyaromatic derivative containing carbon and optionally containing one or more heteroatoms of oxygen, nitrogen and sulfur; X is alkyl, benzyl, or hydroxyl; each of nand n, independently, is an integer of 0&#x2013;8; and a, b, and c are integers when a and c respectively are not zero.
