Abstract
A coating layer composition including: 30 to 70 wt. % of a polyvinyl chloride; 1 to 5 wt. % of a heat stabilizer; 8 to 24 wt. % of a plasticizer; 2.5 to 30.0 wt. % of a HCl-reactive compound; 3 to 40 wt. % of a filler; and 1 to 8 wt. % of a pigment, based on the total weight of the coating layer composition, wherein the polyvinyl chloride has a K-value in the range of 75 to 100, wherein the HCl-reactive compound is selected from the group consisting of CaCO3, hydrotalcite, zeolite, hydrocalumite, hydroxides of magnesium, hydroxides of aluminum, wollastonite, and mixtures thereof, wherein the filler is selected from the group consisting of talc, mica, pyrophyllite, kaolin, and mixtures thereof, and wherein the filler has a plate-shape.
