Title:
WHITE ALIPHATIC POLYESTER RESIN FILM
Document Type and Number:
Japanese Patent JP2017128096
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a white aliphatic polyester resin film which improves a light diffusion effect of the surface, for instance, can improve luminance unevenness of a liquid crystal display device screen.SOLUTION: There is provided a white aliphatic polyester film which has A layer formed from a resin composition A containing an aliphatic polyester resin and a resin incompatible with the aliphatic polyester resin, on at least one of B layer formed from a resin composition B containing at least an aliphatic polyester resin and a filler, and is stretched by twice or more in at least an uniaxial direction, where a content of the resin incompatible with the aliphatic polyester resin is 15 vol.% or more and 45 vol.% or less with respect to the whole resin composition A, and storage elastic modulus and melt viscosity of the aliphatic polyester resin and the resin incompatible with the aliphatic polyester resin at a predetermined temperature satisfy a specific relationship.SELECTED DRAWING: None
