Problems solved by technology

[0004] For example, heat-insulating substrates have a problem that the outermost surface may be scratched during the attachment work on window glass, etc., and this scratching becomes the main cause of scratches.
In this outermost layer (the layer below the protective film), there is also a problem of scratches caused by scratches in daily use, and excellent scratch resistance is strongly required.

Abstract

Provided is a heat-shielding heat insulating substrate having excellent scratch resistance on the surface of a protective film and excellent scratch resistance in the outermost layer remaining after the protective film is peeled off. This heat-shielding heat insulating substrate comprises a transparent substrate layer and an infrared reflection layer, wherein a protective topcoat layer is disposedon the reverse side of the transparent substrate layer-side of the infrared reflection layer, a protective film is disposed on the reverse side of the infrared reflection layer-side of the protectivetopcoat layer, the 180 degree peel strength of the protective film with respect to the protective topcoat layer in an environment having a temperature of 23+ / -1 DEG C and a humidity of 50+ / -5% RH is0.01-0.40 N / 50 mm, and the 180 degree peel strength of the protective film with respect to the protective topcoat layer after storage in an environment having a temperature of 80+ / -1 DEG C is 0.01-1.0N / 50 mm.

Description

technical field [0001] The present invention relates to thermally and thermally insulating substrates. Background technique [0002] The thermal insulation substrate is a substrate that has both a heat insulation function and a heat insulation function. Such a heat-insulating substrate, for example, when attached to window glass or in the case of an integrated form with window glass, can suppress the inflow of solar radiant heat (near-infrared rays) from outdoors to indoors and The outflow of heating heat (far-infrared rays) from indoors to outdoors can improve indoor comfort and energy-saving effects throughout the year. [0003] As such a heat-insulating substrate, in recent years, a heat-insulating film including a base material layer and an infrared reflection layer has been proposed (Patent Documents 1 and 2). The infrared reflective layer has, for example, a configuration in which metal oxide layers are provided on both sides of the metal layer, and can achieve both ...
