摘要:
A solid drawing material containing a gel-forming substance of an alkali metal salt or an ammonium salt of an aliphatic carboxylic acid having 8 to 36 carbon atoms, an alkoxylated nitrogen-containing compound, a reduced starch saccharide, and a coloring agent. The solid drawing material which is in the form of a stick features a large strength, a small drawing resistance, is less subject to be collapsed or broken, produces little shavings while drawing, makes it possible to favorably form a drawing even on smooth surfaces such as windowpanes, and of which the traces after drawn can be easily wiped out with a wet cloth.
