Heat radiation reflective film and method for producing the same, and heat radiation reflector

摘要

To provide a heat radiation reflective film which has a high heat radiation reflectance and good adherence property (peel resistance), which can have a large surface area, and which de-emphasizes certain visible reflected lights; and a method for producing the film. And to provide a heat radiation reflector which includes the heat radiation reflective film as described above. A heat radiation reflective film comprising: at least one heat radiation reflective unit on one surface of a support, the unit comprising: at least 6 laminated layers, each layer having a different refractive index from an adjacent layer, wherein a first unit as one of the heat radiation reflective units comprises the layer closest to the support having a thickness which is 3 times or more of the thickness of the layer farthest from the support.

1. A heat radiation reflective film comprising:
at least one heat radiation reflective unit on one surface of a support, the unit comprising: at least 6 laminated layers, each layer having a different refractive index from an adjacent layer, wherein a first unit as one of the heat radiation reflective units comprises the layer closest to the support having a thickness which is 3 times or more of the thickness of the layer farthest from the support, the layers which constitute the first unit adjoin each other via a blended region having a thickness 0.4-0.8 times the thickness of the layer farthest from the support, and the heat radiation reflective unit includes metal oxide particles and a water-soluble polymer in at least one layer.
