Problems solved by technology

[0004] However, until now, there has been little research on infrared reflective materials for leather products or resin molded products.
In particular, leather products are prone to heat deterioration, especially natural leather, and it is difficult to maintain a characteristic touch or aesthetics when exposed to sunlight for a long time
[0005] In addition, most of the infrared reflective coatings discussed in the past are coatings designed for outdoor use, not for leather products or resin molded products

Abstract

Provided are: an infrared-reflective paint for natural and artificial leather; leather articles using the same; a resin composition that has infrared-reflecting function; and resin moldings using the resin composition. An infrared-reflective paint for natural and synthetic leather, wherein 0.1 to 50wt% of an infrared-reflecting pigment that exhibits a peak with a reflectance of 10% or more in a wavelength region of 750 to 2600nm is contained in a resin component that can constitute a paint solid matter having an elongation of 30% or higher and that has a glass transition temperature of -30 to 90 DEG C; and an infrared-reflective resin composition, wherein 0.05 to 70wt% of an infrared-reflecting pigment that exhibits a peak with a reflectance of 10% or more in a wavelength region of 750 to 2600nm is contained in a thermoformable thermoplastic resin component.

Description

technical field [0001] The present invention relates to an infrared reflective paint and an infrared reflective resin composition that reflect infrared rays contained in sunlight or the like. In particular, it relates to a paint for natural leather and artificial leather having an infrared reflective function, a leather product using the paint, a resin composition having an infrared reflective function, and a resin molded article using the resin composition. Background technique [0002] In recent years, from the perspective of energy saving and countermeasures against the urban heat island phenomenon, it has been studied to suppress heat storage and prevent temperature rise by coating roads, roofs or outer walls of buildings with infrared reflective paints (see Patent Documents 1 and 2). [0003] During the daytime in summer, the indoor temperature of a car or building rises sharply, and the surfaces of indoor items exposed to such an environment, such as car seats, steerin...
