Problems solved by technology

[0004] However, carbon black absorbs infrared rays, so when a decorative material containing carbon black is used in a place that receives a lot of sunlight, defects such as deformation of the decorative material and peeling of the adherend from the decorative sheet may occur due to an increase in the temperature of the decorative sheet.
That is, a decorative sheet in which a solid printing layer and a pattern layer are formed using an ink containing carbon black has insufficient heat insulation properties.

Abstract

Provided is a decorative sheet capable of expressing a design excellent in dark color degree while satisfying heat shielding property. The decorative sheet has, on an infrared-reflective substrate, adecoration layer including a solid printed layer and a pattern layer, wherein the solid printed later contains an infrared-reflective or infrared-transmissive pigment and a binder resin, and the infrared-reflective or infrared-transmissive pigment comprises: (A) three or more kinds of compounds selected from the group of pigments consisting of quinacridone, isoindolinone, nickel azo complex, and phthalocyanine; or (B) one or more compounds selected from the group of pigments consisting of a composite oxide containing manganese and at least one metal element other than manganese, an azo-azomethine compound, and a perylene compound, and wherein at least a part of the pattern layer contains carbon black and a binder resin.

Description

technical field [0001] The present invention relates to a decorative sheet and a decorative material using the same. Background technique [0002] For buildings or structures such as floors, walls, windows, doors, handrails, fences, fences, and pedals (Japanese: 箦子), it is proposed to attach and decorate substrates (adhered objects) such as metal components, resin components, and wooden components. slices to enhance design ideas. In addition, what bonded a decorative sheet to a base body (adhered body) is called a "decorative material" hereinafter. [0003] These decorative pieces are sometimes manufactured in dark colors to impart a sense of luxury. In order to adjust the decorative sheet to a dark color, generally, a solid printing layer and a pattern layer are formed using an ink containing carbon black, which is a general-purpose black pigment. [0004] However, carbon black absorbs infrared rays. Therefore, when a decorative material containing carbon black is used i...
