摘要:
Disclosed herein is a method for evaluating scratch resistance of a plastic resin comprising scratching a surface of a test sample of plastic resin using a scratch apparatus to form a scratch of the surface having a scratch profile; scanning the scratched test sample with a surface profile analysis apparatus to measure the scratch profile; and creating a scratch resistance evaluation index based on the measured scratch profile to evaluate the scratch resistance of the test sample. The method has good reliability and reproducibility, reduces measurement time and errors caused by measurers and measuring conditions, provides easy measurement and can be widely applied to all plastic resins.
摘要:
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.

摘要:
The present invention relates to a capacitive touch sensor and, more particulaly, to a capacitive touch sensor integrated with window panel. The capacitive touch sensor integrated with window panel according to the present invention a transparent window panel substrate; a non-conductive opaque decorative layer formed on a surface of the substrate along the edges of the substrate to define a transparent window area (W) on the substrate; a transparent electrode pattern layer formed over the window area (W) of the substrate and the decorative; and a conductive wiring pattern layer formed at an edge of the transparent electrode pattern layer. The conductive wire pattern layer is disposed in such a manner that it is concealed by the opaque decorative layer. As the touch sensor of the present invention is integrated with the window panel, no additional substrate (PET) on which transparent electrodes are patterned is not required and the thickness of the touch sensor is can be reduced. Also, the touch sensor of the present invention does not require any adhesive for bonding to a separate substrate, which reduces its manufacturing costs.
摘要:
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 including 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.
