The present invention relates to a moisture and oxygen barrier laminate including an inorganic barrier layer and a protective layer sequentially formed on one surface of a light-transmitting substrate, and having a particular change in water vapor transmission rate before and after retort processing or before and after tests via Gelbo flex tester.

Moisture and oxygen barrier laminate

This invention relates to a complex prism sheet which is configured such that heat-resistant coating layers are formed on both surfaces of a substrate layer, thus preventing wrinkling or curling of the complex prism sheet due to heat generated from a light source, and increasing concealment and electro-optic characteristics, ultimately improving properties of a light crystal display. This complex prism sheet can be usefully applied to television (TV) sets, monitors, notebook personal computers (NBPCs), etc., which are required to have heat resistance, slimness and concealment because of an increasing use of a light emitting diode (LED) light source these days.

Complex prism sheet

Disclosed is a process for preparing polyurethane particulate and polyurethane particulate prepared therefrom. The polyurethane particulate has properties such that it is easy to control to a spherical form, the polyurethane particulate can be prepared in a desired particle size, the color thereof is stably exhibited, a washing process thereof is easy because almost no foam is generated in the washing process, and the preparation cost can be lowered because the particles do not lump and a separate grinding process is not needed, by using an inorganic suspension stabilizer in the manufacture process of the polyurethane particulate.
