PROBLEM TO BE SOLVED: To provide a white reflection film capable of sufficiently suppressing sticking with a light guide plate in an ordinary state and suppressing sticking with the light guide plate even under wet heat environment regardless of a water-based coating layer.SOLUTION: The white reflection film has a water-based coating layer consisting of a binder resin and containing particles on the surface of a reflection film. On the surface of the coating layer, a coverage by the particles is 0.2-50%, and an average exposure rate of the particles is 2-97%. The binder resin contains a crosslinking group containing acrylic modified polyester resin of 30 mass% or more on the basis of mass of the binder resin. The amount of a crosslinking group in the crosslinking group containing acrylic modified polyester resin is 60 mol% or more and 200 mol% or less on the basis of 100 mol% of a polyester component in the crosslinking group containing acrylic modified polyester resin. |
