Magnetically interactive substrate for a book

Abstract

A magnetically interactive substrate is provided for a book. The book includes a plurality of interactive substrates in the form of a sheet or a panel of material. Each of the interactive substrates includes magnetizable areas or portions printed thereon. The magnetizable areas are printed using a magnetic ink formulated by magnetizable particles added to an ink formulated for a preselected printing process. The magnetizable particles are shaped and sized to be compatible with the preselected printing process. A plurality of removable play pieces are adapted to be attracted to the magnetizable areas on the substrate. Each of the removable play pieces includes a substrate or support member on which magnetic material is applied. The magnetic material allows the play piece to be selectively positioned on the magnetizable areas. In the preferred embodiment, the magnetizable areas are magnetized to have a specific direction of polarization so that the removable play pieces can be positioned on the magnetizable areas in only one manner.
