Abstract

The present invention produces a surface-treated substrate by a method including a step of selectively modifying the surface of a substrate by applying a composition to the surface of the substrate. The composition contains an onium salt having a nitrogen-containing heterocyclic ring and a monovalent organic group having 4 or more carbon atoms, and water in an amount of 1% by mass or more relative to the total amount of the composition.
