The binder includes a (meth)acryl-based binder including a first structural unit derived from (meth)acrylic acid, (meth)acrylate, or a salt thereof, a second structural unit derived from hydroxyalkyl (meth)acrylate, and a third structural unit derived from (meth)acrylamido sulfonic acid or a salt thereof. The filler includes an organic filler and an inorganic filler. The organic filler includes a cross-linked polymer filler. The inorganic filler includes one or more of a first inorganic filler, which has an average particle size of 50 to 250 nm and is cubic, and a second inorganic filler, which has an average particle size of 100 to 350 nm and is amorphous.",
