PIGMENT COMPOSITION FOR CAMOUFLAGE CLOTH, CAMOUFLAGE SHEET, AND CAMOUFLAGE COATING

摘要

PURPOSE:To provide the titled compsn. useful. as a camouflage material for use in a forest zone, showing an intensive spectral reflectance curve in a far-infrared region, comprising green and blue inorg. calcined pigments or comprising a yellow pigment together therewith. CONSTITUTION:A pigment compsn. for a camouflage coating comprising one or more inorg. calcined pigments selected from the group consisting of CoO:Al2O3: Cr2O3 (mol ratio 1:1-3:0.01-0.07); CoO:Al2O (mol ratio 1:1-3); TiO2:CoO:NiO: ZnO (mol ratio 1:0.3-1.5:0.3-1.5:0.3-1.5) or an azo or isoindolenone yellow pigment together with the above pigments is prepd. A synthetic resin with which said compsn. is blended is molded in a sheet or fibrous form to yield a camouflage cloth or camouflage sheet. EFFECT:The compsn. shows intensive spectral reflectance characteristics in a far-infrared region of 700-800nm in the same manner as chloroplast, when subjected to remote sensing, infrared detector, or infrared photography, and it has an excellent effect as a camouflage material for use in a forest zone.
