发明名称 REFLECTION SHEET
摘要 Provided is a reflection sheet configured from two or more layers consisting of at least a surface layer portion and an inner layer portion. The refection sheet is characterized in that the surface layer portion contains at least a thermoplastic resin (C), and the inner layer portion contains a thermoplastic resin (A) and at least one type of thermoplastic resin (B) that is incompatible with the thermoplastic resin (A), the reflected light intensity in a direction perpendicular to the surface of the reflection sheet when light is incident at an angle of incidence of 60 degrees with respect to the perpendicular direction has anisotropy depending on the incident direction in the entire reflection sheet including the surface layer portion and the inner layer portion, and the ratio L1/L2 between a reflected light intensity L1 in the perpendicular direction in an incident direction A1 in which the reflected light intensity in the perpendicular direction is the highest and a reflected light intensity L2 in the perpendicular direction in an incident direction A2 orthogonal to the incident direction A1 is 1.2 or more.
