PROBLEM TO BE SOLVED: To provide a solid drawing material, capable of smoothly drawing, not only on ordinary quality paper, but also on a smooth non-absorbing surface such as coated paper, plastic, metal, glass or white board to such a degree that a basic pattern or character is visible, further specifically, capable of clearly drawing on a transparent plate surface such as transparent plastic or glass in such a degree that the basic pattern or character is visible, and further capable of being easily erased, in the drawing on such a non-absorbing surface, with a fabric, tissue paper, a white board eraser or the like.SOLUTION: A solid drawing material contains, at least, a resin component, a wax component, a pigment, and a white extender material such as boron nitride or silica. The solid drawing material contains, as the resin component, at least one of rosin and a modified rosin in the range of ≥0.5 wt.% and ≤20 wt.%; and contains, as the wax component, at least one of a glycerol fatty acid ester and a pentaerythritol fatty acid ester having a melting point of ≥45°C in the range of ≥8 wt.% and ≤50 wt.%. |
