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.

The additive to prevent static-electricity by lowering the solid resistance on the surface. The addition or coating of this agent lowers the surface resistance of the materials such as plastics, rubber or fabrics. Surface-activator, inorganic salt, polyhydric alcohol, metal compounds or carbon is used as anti-static agent.
