Improvements Relating to Sheet Materials for Use in the Creation of Sketches, Drawings, Designs and the Like

摘要

The invention provides a sheet material having a base sheet 10 and a coating 20. The coating 20 can be scratched away by means of a sharp pointed tool 26 for the creating of sketches, pictures, patterns and designs, (which may be pre-defined within the coating) in that the coating 20 is of a colour which contrasts with that of the revealed surface of the base sheet 10 along the lines of scratching. The base sheet 10 is preferably of paper or board and is of such flexibility that it can be bent round a one inch bar without it or the coating cracking. IMAGE
