Abstract: An aqueous coating material for synthetic papers includes 26 wt % to 75 wt % of an acrylic emulsion, 2 wt % to 10 wt % of hollow latex microspheres and 26 wt % to 70 wt % of an inorganic ink-absorbing material. Each of the hollow latex microspheres has a particle size between 500 nm and 1100 nm, and includes a hollow core, a buffering layer covering the hollow core, and a shell covering the buffering layer. The aqueous coating material can be applied onto a surface of a synthetic paper substrate and formed into a surface coating layer.
