Abstract of the Disclosure A pressure-sensitive adhesive tape having a camouflaged appearance has a cellular or foamlike pressure-sensitive core layer and at least one relatively thin, dense, pigmented pressure-sensitive adhesive surface layer. The thickness of the core layer may be about 1.0 mm and that of a surface layer about 0.03 mm. The surface layer of such a composite tape appears to be more intense in color than does either the core layer or the surface layer by itself. When viewed edgewise, the composite tape appears to present a color that is more intense than one would expect from viewing the edges of the core layer and surface layer by themselves.
