The present invention relates to workbooks and is particularly concerned with workbooks having erasable pages.
There are known workbooks having pages with at least a portion thereof bearing an erasable surface. Typically, these include children's books for practicing printing or drawing. One such example is EP 0309106 (B1) published Nov. 13, 1991.
Other offerings include hybrid articles combining a dry-erasable panel along with paper pages. One example is U.S. Patent Pub. 20120129146.
An object of the present invention is to provide an improved workbook.
In accordance with an aspect of the present invention there is provided a workbook comprising a plurality of pages, each page having at least one writing surface upon which a dry-erasable pen can write and be erased for repeated use of the writing surface.
In accordance with another aspect of the present invention there is provided a workbook page having at least one writing surface upon which a dry-erasable pen can write and be erased for repeated use of the writing surface.
In accordance with a further aspect of the present invention there is provided a writing kit comprising a workbook having a plurality of pages, each page having at least one writing surface upon which a dry-erasable pen can write and be erased for repeated use of the writing surface and a pen compatible with the writing surface.
The present invention will be further understood from the following detailed description with reference to the drawings in which:

Details of the layers are as follows. The substrate 24 of the present embodiment is a conventional paper medium, however any suitable substrate including cardboards, card stocks, and synthetics could also be used. The paper substrate 24 was coated on both surfaces with a water-based film 26, that is the substrate 24 with the water-based film 26 was a coated paper. The water-based film had a satin finish. The writing surface 32 was prepared by applying two layers 28 and 30 to at least one surface of the water-based film 26. The layers 28 and 30 were UV films. In one example the layer 28 is a water-based UV film and the layer 30 is another UV film having a gloss finish.
Specific examples of the latter film are UV 9296 and UV 9613 by Actega Kelstar Canada Inc., of Chomedey Quebec.
Alternative embodiments may use known paper-based substrate coated with film. Synthetic substrates may be selected that do not require a coating layer, in which case the coating layer 26 is omitted.
The workbook may includes pages on which one of the substrate, the first UV film and the layer there between includes printed matter, for example grids, lines, polar plots, music staff, guitar tablature and bass tablature.
Numerous modifications, variations and adaptations may be made to the particular embodiments described above without departing from the scope patent disclosure, which is defined in the claims.
