Title:
EXTERIOR DECORATIVE MATERIAL
Document Type and Number:
Japanese Patent JPH1148437
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To permit the prevention of temperature rise even when an exterior decorative material is exposed to solar beams in spite that the material is colored by a dark color. SOLUTION: A solar infrared ray transmitting dark color resin layer 2 is laminated on the surface of a solar infrared ray reflecting substrate 1. A protecting layer can be provided on the dark color resin layer 2 in order to provide with weather resistance. The dark color resin layer 2 is constituted of the combination of two kinds or more of coloring agents, which are provided with the peak of absorption in only a part of wave length area in visible rays band area and provided with transmitting property in all band area of solar infrared rays while providing an absorption spectrum covering whole area in the visible rays band area by superposing all of the absorption spectrum band area of respective coloring agent or at least the dark color resin layer 2 is constituted of the mixture of solar infrared rays transmitting resins, transmitting at least the whole band area of the solar infrared rays. Infrared rays in the solar beams are reflected without being absorbed even when the material is exposed to solar beams whereby temperature rise due to radiation heat can be prevented.
