RESIN COMPOSITION FOR REFLECTING PLATE

摘要

A first resin composition for a reflecting plate which comprises 30 to 95 wt % of a semi-aromatic polyamide containing an aromatic monomer unit in a conten t of 20 mole % or more and 5 to 70 wt % of a potassium titanate fiber and/or wollastonite; and a second resin composition for a reflecting plate for use in an ultraviolet ray producing source which comprises a thermoplastic resin an d at least one inorganic compound in the form of a fiber or a small and thin plate being capable of reflecting ultraviolet rays as well as visible rays. The first and the second resin compositions can be suitably used for produci ng a reflecting plate which can combine high levels of various properties required for a reflecting plate, such as mechanical strength, thermal resistance, dimensional stability, light reflectivity, light shading propert y and the like, and a reflecting plate which has the above characteristic of t he first one and also can achieve satisfactory reflectivity i.e. brightness eve n when used in a white LED having an ultra-red light emission element, respectively.
