The polyethylene wax used in the present invention is a pyrolyzable low-density type, which has a higher melt viscosity per molecular weight than other general polyethylene waxes such as ethylene polymerization type or by-product type, and has excellent flexibility and adhesiveness. In addition, because it has a low softening point, it easily melts due to the frictional heat when writing, increases stickiness, and forms a thick coating film on the paper surface, leaving no trace of drawing marks even on smooth paper surfaces. It is thought that the concentration will increase.
