<p>The utility model aims to provide a white board paper used for coating. The white board paper has good performance in white paper gloss and smoothness and has good polishing gloss. The white board paper is composed of more than two coating layers mainly composed of pigments and adhesive. The pigment on the surface coating contains pin-shaped or cylinder-shaped light calcium carbonate. 50% granule size (D50) of the granule distribution curve of the light calcium carbonate obtained through a laser diffraction method is 0.2 to 0.7 micrometer and the ratio of D90 and D10 is lower than 8.</p> |
