摘要： PROBLEM TO BE SOLVED: To provide a novel reflection film having excellent light reflection properties, wherein resin waste deposition in a manufacturing process and production of spitting on the surface of the film will not occur.
SOLUTION: In the reflection film having a resin composition layer containing a polyolefin-based resin, a powdery filler and a metal soap based lubricant, the powdery filler is provided with an inactive inorganic oxide layer comprising at least one inactive inorganic oxide selected from the group consisting of silica, alumina and zirconia and occupying 0.5 to 5 mass% of the total mass of the powdery filler and the metal soap based lubricant is a stearic acid based compound, or a palmitic acid based compound, or both compounds. Since the resin waste deposition will not be produced in the manufacturing process and the spitting is not caused on the surface of the film by blending the metal soap based lubricant, the film having satisfactory product appearance can be manufactured stably, without causing breakage during extension film formation.

摘要： PROBLEM TO BE SOLVED: To provide an aliphatic polyester reflective film which has an excellent reflective performance and is used for a reflection plate for a liquid crystal display and the like. SOLUTION: The aliphatic polyester reflective film has a layer A consisting of a resin composition A containing an aliphatic polyester resin, a particulate filler and a liquid additive (e. g. paraffin process oil or a plasticizer). The film has a high reflective performance, is not liable to lose the reflectance by ultraviolet absorption and excellent in yellowing resistance. In particular the addition of the liquid additive prevents deterioration of the performance due to thermal degradation during manufacture, which leads to further improvement in the reflectance.

摘要： PROBLEM TO BE SOLVED: To provide a novel reflection film improving light reflectivity and dimensional stability under a heated condition. SOLUTION: The reflection film is provided with a layer A containing an aliphatic polyester based resin and a powdery filler, a layer B containing a polyolefin based resin and a powdery filler and a layer C composed of a biaxially oriented polyester film. Light reflectivity can be obtained from refractive scattering due to difference between refractive indices of the aliphatic polyester based resin and the powdery filler in the layer A and light transmitted through the layer A can be reflected again in the layer B. Thereby, higher reflectivity can be obtained. The layer C can reduce dimensional change of the film at 80°C and dimensional stability under the heated condition is increased.
