PROBLEM TO BE SOLVED: To provide film coating compositions in which adhesion between tablets hardly occurs even when coated using PVA with saponification degree of 85.0 to 89.0 mol% and adding no additives other than PVA, to provide oral solid formulations using the same, and to provide manufacturing method thereof.SOLUTION: Provided is a film coating composition containing a PVA polymer having an average saponification degree of 85.0 to 89.0 mol%, which satisfies the following requirement (A) or (B). Requirement (A): The transparency of a solution obtained by adding 130.0 ml of 1-propanol to 100.0 g of a 5.0% by mass aqueous solution of a PVA polymer and stirring the solution is 50.0% or less at 20°C. Requirement (B): The concentration of the supernatant obtained by adding 230.0 ml of 1-propanol to 100.0 g of a 5.0% by weight aqueous solution of a PVA polymer and stirring and by allowing the stirred solution to stand at 20°C for 24 hours is 0.75 mass% or more.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】けん化度が８５．０～８９．０モル％ＰＶＡを使用し、ＰＶＡ以外の添加剤を加えずにコーティングを行った場合にも、錠剤同士の付着が発生しにくいフィルムコーティング組成物、それを用いた経口固形製剤及びその製造方法を提供する。【解決手段】下記要件（Ａ）又は（Ｂ）を満たす、平均けん化度が８５．０～８９．０モル％のＰＶＡ系重合体を含むフィルムコーティング組成物である。要件（Ａ）：ＰＶＡ系重合体の５．０質量％水溶液１００．０ｇに対して、１－プロパノールを１３０．０ｍｌ加え、撹拌して得られる液の２０℃における液の透明度が５０．０％以下。要件（Ｂ）：ＰＶＡ系重合体の５．０質量％水溶液１００．０ｇに対して、１－プロパノールを２３０．０ｍｌ加え、撹拌した液を、２０℃で２４時間静置して得られる上澄み液の濃度が０．７５質量％以上。【選択図】なし
