Provided are a toner using a resin having an active hydrogen-containing group, and a method of preparing the toner. The toner using a resin having an active hydrogen-containing group includes a binder resin (A), a cross-linked resin having a THF insoluble content of 99 - 100 weight %, a colorant, and at least one additive. The cross-linked resin is arranged in the form of a plurality of islands in each particle of the toner. Accordingly, the toner can prevent hot offset. Also, the toner can be used in an electrophotographic image forming apparatus.
Abstract:
The present invention provides a method of preparing a hyperbranched organic modifier which comprises reacting (a) a tertiary amine compound having at least two terminal hydroxyl groups with (b) at least one multifunctional monomer having at least two terminal functional groups capable of reacting with said hydroxyl groups. The present invention also provides an organo- modified clay treated with the hyperbranched organic modifier.
Abstract:
Provided are a method of preparing a toner having a core-shell structure and a toner prepared using the method. The method includes: preparing a mixture by mixing a resin with acid groups, a coloring agent and at least one additive with an organic solvent, and neutralizing the acid groups of the resin with a base; forming a micro-suspension solution by adding the mixture to a dispersion medium; forming a toner core by removing the organic solvent from the micro-suspension; and forming a toner complex having a core-shell structure by seed-polymerizing at least one monomer on the surface of the toner core. Thus, the toner that can prevent hot offsets, improve storage stability at a high temperature and improve charge stability against environment changes can be prepared with reduced costs according to the method. In addition, the toner can be applied to an electrophotographic image forming device.
Abstract:
Disclosed herein is a thermoplastic nanocomposite resin composition comprising: (A) about 100 parts by weight of a thermoplastic resin; and (B) about 0.1 to about 50 parts by weight of metal (oxide) nanoparticles, the surfaces of which are organically modified with a silane compound. In the thermoplastic nanocomposite resin composition of the present invention, metal (oxide) nanoparticles are uniformly dispersed into a thermoplastic resin matrix due to hybrid bonding between the resin matrix and the organo-surface modified metal (oxide) nanoparticles, so that the thermoplastic nanocomposite resin composition may have considerably improved scratch resistance against surface damage of molded articles.

The present invention provides a polymerization toner having superior anti-static and storing properties. The polymerization toner comprises a binder resin and a colorant, and the dielectric rate of the binder resin is between 2.8 and 3.7.
Abstract:
According to the present invention, a capacitive touch sensor integrated into a window panel comprises: a window panel substrate made of a transparent material; a nonconductive opaque decorative layer formed at the edge of one surface of the substrate to define a transparent touch window region (W) on the substrate; a transparent electrode pattern layer formed over the entirety of the window region (W) and the decorative layer of the substrate; and a conductive wiring pattern layer formed at the edge of the upper surface of the transparent electrode pattern layer. The conductive wiring pattern layer is arranged to be covered by the opaque decorative layer. The touch sensor according to the present invention is integrally formed with the lower surface of a window panel, to thereby eliminate the necessity of a substrate (PET) on which a transparent electrode is patterned, and to thus reduce the thickness of the touch sensor. In addition, the touch sensor according to the present invention eliminates the necessity of an adhesive for attaching the touch sensor to the substrate, thereby reducing manufacturing costs.
