<p>PURPOSE:To obtain a solid drawing material smoothly drawable on art paper, etc., with high concentration of drawn trace without inducing dirty hand even using the drawing material itself in a hand comprising pigment, an olefin-based resin, wax, fatty acid amide, mineral oil and a specific resin such as rosin. CONSTITUTION:The aimed drawing material is composed of pigment (e.g. carbon black or titanium oxide) preferably in an amount of 3-30wt.%, an olefin-based resin (e.g. PE or PP) preferably in an amount of 10-40wt.%, wax (e.g. PE wax or beeswax) preferably in an amount of 10-40wt.%, fatty acid amide (preferably stearic acid amide) preferably in an amount of 2-10wt.%, mineral oil(e.g. liquid paraffin) preferably in an amount of 1-4wt.% and at least a resin selected from rosin, ester gum, coumarone resin and alkyd resin preferably in an amount of 3-15wt.%.</p> |
