Abstract
A composition includes a polymer and a solvent. The polymer includes a group (X) which is at least one selected from the group consisting of: a group including at least two cyano groups; a group including —B(OR)2; a group including —PO(OR)2; and a group including —P(OR)2. Each R independently represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms. The polymer preferably includes the group (X) at an end of a main chain thereof or at an end of a side chain thereof.
Claims9
A method of producing a substrate, the method comprising:
- applying a composition directly or indirectly on a base material to form a coating film;
- and
- heating the coating film,
- wherein:
- the base material comprises a surface layer which comprises:
- a first region comprising a metal atom;
- and
- a second region not comprising a metal atom;
- the base material comprises a metal atom at least one of in or on at least a part of the surface layer;
- and
- the composition comprises:
- a polymer comprising a group (X) which is at least one selected from the group consisting of:
- a group comprising at least two cyano groups;
- a group comprising —B(OR)2;
- a group comprising —PO(OR)2;
- and a group comprising —P(OR)2, wherein, each R independently represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms;
- and
- a solvent.
