CELLULOSE ESTER FILM AND METHOD FOR PRODUCING THE SAME, POLARIZING PLATE, OPTICAL COMPENSATION FILM, ANTIREFLECTION FILM, AND LIQUID CRYSTAL DISPLAY DEVICE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a cellulose ester film having excellent ultraviolet-absorbing characteristics without being deteriorated even in a high-temperature melt production process, and also having excellent surface property. <P>SOLUTION: The cellulose ester film having 20-300 μm thickness is formed by: melting a mixture containing 100 pts.mass of the cellulose ester having a specified substitution degree, and 0.2-3 pts.mass of an ultraviolet absorbent represented by general formula (1) (wherein, R<SP>1</SP>and R<SP>2</SP>are each H, a halogen atom or an alkyl group; and R<SP>3</SP>to R<SP>6</SP>are each an alkyl group or an aryl group) and having ≥500 molecular weight at 180-240°C; and extruding the melted product from a die. <P>COPYRIGHT: (C)2007,JPO&INPIT |
