A tablet comprising a core which is at least partially coated with an outer layer obtained by electrostatic deposition of a powder and subsequent fusing of the deposited powder to form a film characterised in that a surface of the tablet coated with said outer layer is contoured to provide higher regions and lower regions, the outer layer having a different colour in said lower regions to the outer layer in said higher regions.

Tablets with coloured patterns and preparation thereof

An apparatus for electrostatically applying a powder material to a solid dosage from includes a source () of charged powder material, a support assembly () for supporting the solid dosage form () with a front face in the vicinity of the source of powder material and facing the source of powder material, the support assembly () including an electrically conducting member () in the vicinity of the rear face of the solid dosage form and an electrically conducting shield () disposed closely around the solid dosage from () between the front face and the rear face of the solid dosage form, and means () for creating a potential difference between the source of powder material and the electrically conducting member and for maintaining the electrically conducting shield at a potential more similar to that of the source of powder material than to that of the electrically conducting member.

Electrostatic application of powder material to solid dosage forms utilizing an electrically conductive shield

In a method of electrostatically applying a powder material to a solid dosage form, charged powder material is applied to a photoconductive drum ( ), is transferred to an intermediate belt ( ) and then to a solid dosage form ( ). The belt ( ) makes contact with the solid dosage form ( ).
