Document Type and Number:
WIPO Patent Application WO/2018/110461
Kind Code:
A1
Abstract:
The present invention provides: a surface treatment liquid which is capable of performing good hydrophilization or hydrophobization of the surface of an object to be treated even if the surface treatment liquid does not contain a coating film-forming resin; and a surface treatment method which uses this surface treatment liquid. A surface treatment liquid which contains a resin (A) and a solvent (C), and wherein a resin which has a functional group I that is a nitrogen-containing heterocyclic group and a functional group II that is a functional group other than the functional group I and is composed of one or more groups selected from among hydrophilic groups and hydrophobic groups, and which contains one or more constituent units selected from the group consisting of a constituent unit (a1) that has the functional group I, a constituent unit (a2) that has a cationic group in a side chain, and a constituent unit (a3) that has an anionic group in a side chain, is used as the resin (A).
