Composition, undercoat layer, electrode, and lithium-ion secondary battery

Abstract

The composition of the disclosure contains a conductive carbon material (A), an olefin resin (B), and an acrylic water-soluble polymer (C). The acrylic water-soluble polymer (C) has a structural unit derived from a (meth)acrylamide, and a structural unit derived from a vinyl monomer having at least one of a carboxy group or a hydroxy group. A content of the structural unit derived from a (meth)acrylamide is from 35% by mass to 95% by mass with respect to a total amount of the acrylic water-soluble polymer (C). A content of the structural unit derived from a vinyl monomer having at least one of a carboxy group or a hydroxy group is from 5% by mass to 65% by mass with respect to the total amount of the acrylic water-soluble polymer (C).

Dependencies are inferred from the claim text.
