The pigment to make metallic ink. Aluminium paste is the mixture of flaky aluminium and solvent. There are two types, leafing and non-leafing. In leafing type, flaky aluminium piles up like foliage, which makes glittering metallic gloss, although the chalking resistance on the printed surface is inferior to that of non-leafing type. The paste made of resin-coated aluminium is sometimes used for industrial purposes as its properties are better than normal type.
