Abstract: Disclosed is a coating material comprising 100 parts by mass of an acid-modified polypropylene (A) and at least 450 parts by mass of organic solvents (B), wherein the acid-modified polypropylene has a melting point of 90° C. or lower and the organic solvents (B) comprises 80-99 mass % aromatic hydrocarbon solvent (B1) and 20-1 mass % one or more solvents (B2) selected from the group consisting of ester-based solvents, ketone-based solvents, and alcohol-based solvents, the sum of the proportion of the ingredient (B1) and the proportion of the ingredient (B2) being 100 mass %. The coating material may further contain a compound (C) having, in the molecule, two or more functional groups capable of forming a chemical bond with a carboxyl group, in an amount of 0.1-20 parts by mass. The compound (C) having, in the molecule, two or more functional groups capable of forming a chemical bond with a carboxyl group may be one having no hydrolyzable group. Also disclosed are: a coating film formed from the coating material; a layered product comprising the coating film and a substrate film; and a flexible flat cable including the layered product.
