Abstract: The present invention relates to paint compositions which provide a Chemical Agent Resitant Coating (CARC), consisting of one layer topcoat paint system, which imparts an increase in the reflectivity at the thermal infra-red region, while controlling the colour in the visible range and are maintaining a low gloss, comprising: an extender selected from polyolefins and substituted polyolefins; a pigment, selected from a metal oxide calcined at a temperature of above 600.degree. C. and a paste of metal flakes and any mixture thereof; a binder consisting of a modified polyurethane resulted from an isocyanate and a co-reactant possessing at least two hydroxy groups, and a solvent system to dissolve the components in the paint composition.
