摘要： The present invention relates to a white material having a white color in a visible-ray region and absorbing wavelengths in a near-infrared region, a method of manufacturing the same, and uses thereof. More particularly, the present invention relates to a method of manufacturing a near-infrared-absorption material which has a brightness (CIE L*) value of 90 or more in a visible-ray region and which is excellent in particle manufacturing properties, and to the manufacture and uses of products to which near-infrared-absorption and antibacterial properties of the near-infrared-absorption material are provided. In order to accomplish the objects of the invention, a copper pyrophosphate compound having near-infrared-absorption and antibacterial properties is selected. The material manufactured using conventional technologies and methods has a limitation in use due to a green or blue color thereof. However, in the present invention, a material that has a high brightness and is excellent in fine particle properties is manufactured, thus overcoming the limitation related to color. The manufactured copper pyrophosphate compound has various uses and application effects, such as counterfeit prevention, falsification prevention, and device detection of security products, and laser marking and laser welding of plastics using a near-infrared-absorption property, and imparting antibiotic properties to products to which the compound is added.
