Pigmentation of a Camouflage Dye and Investigation of Its Colour and Reflectance Properties
Asian Journal of Chemistry,
Vol. 22 No. 1 (2010): Vol 22 Issue 1, 2010
Abstract
Natural foliage and terrain reflect light both in the visible (380-700
nm) and near infrared (700-900 nm) regions of the electromagnetic
spectrum. In this study, dyes consisting of several different pigment
combinations are proposed intended to meet the camouflage needs fitting
the reflectance properties of local natural green foliage in both visible
and near infrared regions. Camouflage pigment green 179, functionalized
with the appropriate infrared reflectance was mixed with varying
amounts of chromium oxide, iron oxide and carbozel violet pigments
and the spectral reflectance of surfaces treated with this alkide based dye
was measured in the 320-1500 nm interval. Chromaticity and observed
brightness (Y) values were determined using the CIELAB 1976 (L* a* b*)
colour definition systems. Field tests demonstrate that dyes thus obtained,
meet camouflage standards in both the visible and near infrared regions.
