PLANAR SUPPORT WITH TWO FACES FOR WRITING OR DRAWING

摘要

A planar support with two faces on which hand writing and hand drawing may take place includes an assembly of two fibrous layers having the respective faces, and a thermoplastic polymer preparation between the two fibrous layers. The thermoplastic polymer preparation makes the support opaque to direct transmission of light. The thermoplastic polymer preparation is filled with carbon black, chalk, and/or titanium dioxide to scatter and attenuate light in the thermoplastic polymer preparation.

1. A planar support with two faces on which hand writing and hand drawing may take place, the planar support including
an assembly of two fibrous layers having the respective faces, and a thermoplastic polymer preparation positioned between the two fibrous layers, wherein
the assembly is produced by cooling of the polymer preparation from a molten state,the thermoplastic polymer preparation provides opacity of the support and is filled with carbon black and one of chalk and titanium dioxide so that light scattered in the thermoplastic polymer preparation is attenuated while the support retains whiteness of the fibrous layers.
