The present invention relates to a coating structure for a sheet-like substrate containing lignocellulosic fibers. This structure comprises at least one precoat layer, which is polymerized in the presence of (a) stabilizer and has a glass transition temperature Tg of 20° C. or lower (≦), preferably 10° C. or lower (≦). At least 70% by mass of the first styrene (meth)acrylate copolymer, (b) 30% by mass or less (≦) of inorganic plate-like mineral particles such as kaolin or talc, and (c) at least one kind of 0.01 to 2 mass% of the thickener of No. 1 is included. In addition, the coating structure further comprises a topcoat layer, which is polymerized in the presence of (a) a stabilizer and has a glass transition temperature Tg of 20° C. or lower (≦), preferably 10° C. The following (≦) at least 50% by mass of the second styrene (meth)acrylate copolymer, (b) 30% by mass or less (≦) of the inorganic mineral particles, (c) at least one second thickening agent 0.01 to 5 mass% of the agent, and 0.5 to 30 mass% of the anti-blocking agent (d). The present invention further relates to a sheet-shaped product coated with the coating structure. [Selection diagram] None |
