である。This is a high-density polyethylene wax (density = 0.96
~ Q, 98g/cc, 25°C), the density of drawing marks will be low, and pyrolytic low density polyethylene wax (density: 0.90-0.93g/cc, 25
℃), if the molecular weight is less than 2,000 and the melt viscosity is less than 300 cP (140℃), the coating film will easily peel off and the concentration will become low.
This is because when the melt viscosity is greater than 0 and the melt viscosity is greater than 4,500 cP, the density of the drawn mark becomes low.

本発明の固形描画材がアート紙・コート紙などの平滑な
紙面に対して、描画跡の濃度が高くなる理由については

膜が形成され、平滑紙面でも描画跡濃度が高くなると考
えられる。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.
