Fatty acid esters of polyglycerols, such as stearic acid penta(tetra)glyceryl ester, behenic acid hexa(tetra)glyceryl ester, lauric acid mono(deca)glyceryl ester, oleic acid di(tri)glyceryl ester, linolic acid di(hepta)glyceryl ester, palmitic acid deca(deca)glyceryl ester, etc. are employed as coating agents for coating solid preparations such as tablets, pills, granules, fine granules, etc. By coating with the coating agents, stable sustained release of active ingredients contained in the preparations is obtained, even after a long period of storage.
