To provide a reflection film which has excellent light reflectivity, reduces unevenness in brightness in a surface light source, causes neither yellowing nor lowering of the light reflectivity over time by use, ensures good product appearance without spoiling the above performances, and can stably be produced without causing breaking in film forming by drawing.
The aliphatic polyester resin reflection film is formed from a resin composition A containing an aliphatic polyester resin, a titanium oxide, a fine powder filler having a larger average particle diameter than the titanium oxide, and a lubricant. Alternatively, the aliphatic polyester resin reflection film can be obtained by stacking a layer A formed from the resin composition A on at least one surface of a layer B formed from a resin composition B containing an aliphatic polyester resin and a titanium oxide. The lubricant preferably comprises at least one selected from acrylic lubricants and hydrocarbon lubricants.
