LIGHT-DIFFUSING POLYESTER FILM

PROBLEM TO BE SOLVED: To provide a light-diffusing polyester film which exhibits excellent mechanical strength, has a good balance between total light transmittance and light diffusibility, and is free from curling that is caused by a high-temperature treatment. SOLUTION: The light-diffusing polyest...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light-diffusing polyester film which exhibits excellent mechanical strength, has a good balance between total light transmittance and light diffusibility, and is free from curling that is caused by a high-temperature treatment. SOLUTION: The light-diffusing polyester film includes a three-layer structure, obtained by co-extrusion, wherein a light diffusion layer (B) is arranged on one side of an intermediate layer (A) and a smooth layer (C) is arranged on the other side of the intermediate layer (A). In the light-diffusing polyester film, the intermediate layer (A) is composed of a crystalline homopolyester or a crystalline polyester containing a copolymerization component, the light diffusion layer (B) is composed of 50-99 pts.mass of a crystalline polyester containing a copolymerization component the melting point of which is 225-255°C and 1-50 pts.mass of an additive incompatible with the polyester, and the smooth layer (C) is composed of a crystalline polyester containing a copolymerization component the melting point of which is 225-255°C.
