Abstract
Compositions suitable for use as a camouflage material are based on vesiculated granules of polymer material which are substantially free of titanium dioxide but contain a light reflecting agent. The agent is an oxide, hydroxide or insoluble salt of magnesium or an insoluble mixed salt of calcium and magnesium and is present in an amount of at least 10 percent by weight of the polymeric material. Preferably the agent is dolomite. Paints containing the composition are useful as camouflage in snowy conditions and the aqueous paints are removable by scrubbing.
