Zusammenfassung:	To provide a can inner surface coating material for forming a coating film formed on the can inner surface, wherein the coating material suppresses degradation of the contents caused by the coating film, and improves the processability of the coating film.SOLUTION: Provided is a can inner surface coating material including a polymer (A) having carboxy groups, a compound (D) having one functional group (f) capable of reacting with a carboxy group while being free of ethylenic unsaturated bonds, and a liquid medium, wherein the number of functional groups (f) is less than the number of carboxy groups contained in the polymer (A).SELECTED DRAWING: Figure 1 【課題】缶内表面に形成される塗膜を形成する塗料であって、塗膜による内容物の変質を抑制し、塗膜の加工性を改善する缶内表面塗料を提供する。【解決手段】カルボキシ基を有するポリマー（Ａ）と、カルボキシ基と反応可能な官能基（ｆ）を１個有し、エチレン性不飽和結合を有しない化合物（Ｄ）と、液状媒体とを含み、官能基（ｆ）の数は、ポリマー（Ａ）に含まれるカルボキシ基の数よりも少ない、缶内表面塗料である。【選択図】図１
