NON-ORIENTED OPTICAL REFLECTION SHEET HAVING HIGH-WHITENESS AND MANUFACTURING METHOD THEREOF

摘要

A non-oriented optical reflection sheet having high-whiteness and a manufacturing method thereof are provided to reduce a manufacturing process by optimizing resin characteristics. A non-oriented optical reflection sheet includes a core layer(A) and a skin layer(B). The core layer includes a composition having a resin component selected from a polycarbonate rein or a blend resin, which contains the polycarbonate resin and at least one or more copolyester-based resin, white inorganic particles, and one or more fluorescent brightener. The skin layer is formed on both sides of the core layer. The skin layer includes a resin component, a core layer composition, and a composition including the resin composition and silicon particles.
