Coating material, printing member for dot printing, and PTP packaging body

A sealing sheet comprising:

• a printing member for dot printing comprising a printing substrate and a surface layer that is integrated by lamination on a surface of the printing substrate, wherein the surface layer includes a coating film of a coating material;
• and
• a gravure printing layer that is formed on the surface layer, wherein the gravure printing layer includes a number of dots printed by gravure printing,
• wherein the coating material comprises a pigment including an inorganic particulate and a skin layer that is formed on a surface of the inorganic particulate, the skin layer including an organic compound,
• wherein the organic compound included in the skin layer includes a fatty acid or a polyol,
• wherein the fatty acid is selected from the group consisting of octanoic acid, nonanoic acid, and decanoic acid,
• wherein, when the fatty acid is the octanoic acid, a content of the skin layer in the pigment is 0.2 to 0.3% by mass,
• wherein, when the fatty acid is the nonanoic acid, a content of the skin layer in the pigment is 0.2 to 0.4% by mass, and
• wherein, when the fatty acid is the decanoic acid, a content of the skin layer in the pigment is 0.3 to 0.5% by mass,
• wherein the polyol is selected from the group consisting of trimethylolpropane, ditrimethylolpropane, and pentaerythritol,
• wherein, when the polyol is the trimethylolpropane, a content of the skin layer in the pigment is 0.4 to 0.5% by mass,
• wherein, when the polyol is the ditrimethylolpropane, a content of the skin layer in the pigment is 0.2 to 0.3% by mass, and
• wherein, when the polyol is the pentaerythritol, a content of the skin layer in the pigment is 0.4 to 0.5% by mass,
• wherein the coating material comprises vinyl chloride-based resin as a binder, and
• wherein a content of the pigment in the coating material is 100 to 150 parts by mass relative to 100 parts by mass of the binder.
