Abstract

Holograms gives a three dimensional perception by including information on the depth. Electro forming technique has been utilized for duplicating the holoW3pbic designs produced on the optical glass. For the reproduction of the 3D images on the aluminized polyester film hard electrofomled nickel stampers are produced from sulphamate bath. Nickel can be deposited either as a soft coating characterized by excellent ductility or as a hard coating to resist wear and tear depending on the applications. ntis could be achieved by proper conditioning of the sulphamate bath and also by tbe use of suitable addition agents. In this study S-sulpho salicylic acid has been used as an additive to improve the hardness of the deposit for use in the production of holograms.
