Abstract:
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.
Abstract:
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.

Abstract:
The present invention provides a ring-opened polymer, which is prepared by reacting at least one pericyclic olefin elected from those represented by formulae (I) and (II) through ring-opening metathesis polymerization wherein A and B may be the same or different and are independently selected from the group consisting of halogen, hydrogen, C3-20 cyclic or pericyclic alkyl, C1-20 linear and branched alkyl, C6-20 aryl, C7-20 arylalkyl, C7-20 alkylaryl, silyl, alkylsilyl, germyl, alkylgermyl, alkoxycarbonyl, acyl, and a heterocylic group; or, A and B are linked together to form a C3-20 saturated or unsaturated cyclic hydrocarbon group or a substituted or unsubstituted heterocyclic group; C is selected from the group consisting of oxygen, sulfur, —CH2—, and —SiH2—, wherein each R1 is independently selected from C1-20 alkyl and phenyl; each R is independently selected from hydrogen, halogen, and C1-20 alkyl; and each n is an integer from 1 to 6.
Abstract:
The present invention relates to a silicon-containing copolymer which includes a maleic anhydride repeating unit, a norbornene repeating unit, and at least one silicon group-containing norbornene repeating unit. The silicon-containing copolymer is suitable for use as a top layer resist in a bilayer resist system.
Abstract:
The present invention relates to a polymer with at least one pericyclic protective group such as 2-methyl-2-bicyclo[2,2,1]heptanyl. The resist composition containing the polymer can be used as a chemically amplified resist and exhibits strong etch resistance. In addition, a line-and-space pattern of 0.1 &mgr;m pitch can be resolved successfully using the resist composition.
