Resist underlying film-forming composition comprising a reaction product with a glycidyl ester compound

A resist underlying film-forming composition comprising a solvent, and an epoxy addition product, which is a reaction product of an epoxy addition product-forming compound and a compound represented by the following formula (1):

• wherein, in formulae (1), X is a divalent organic group represented by formula (2), (3), or (4) below, and each of n1 and n2 independently represents an integer of 1 to 10:
• wherein, in formulae (2), (3), and (4),
• each of R1 and R2 independently represents a hydrogen atom, an alkyl group having 1 to 10 carbon atoms and being optionally interrupted by an oxygen atom or a sulfur atom, an alkenyl group having 2 to 10 carbon atoms and being optionally interrupted by an oxygen atom or a sulfur atom, an alkynyl group having 2 to 10 carbon atoms and being optionally interrupted by an oxygen atom or a sulfur atom, a benzyl group, or a phenyl group, wherein the phenyl group is optionally substituted with at least one monovalent functional group selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, a halogen atom, an alkoxy group having 1 to 10 carbon atoms, a nitro group, a cyano group, and an alkylthio group having 1 to 6 carbon atoms, and
• R3 represents a hydrogen atom, an alkyl group having 1 to 10 carbon atoms and being optionally interrupted by an oxygen atom or a sulfur atom, an alkenyl group having 3 to 10 carbon atoms and being optionally interrupted by an oxygen atom or a sulfur atom, an alkynyl group having 3 to 10 carbon atoms and being optionally interrupted by an oxygen atom or a sulfur atom, a benzyl group, or a phenyl group, wherein when R3 is a phenyl group, the phenyl group is optionally substituted with at least one monovalent functional group selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, a halogen atom, an alkoxy group having 1 to 10 carbon atoms, a nitro group, a cyano group, and an alkylthio group having 1 to 6 carbon atoms,
• wherein the epoxy addition product-forming compound is a carboxylic acid-containing compound or a thiol group-containing compound, and
• wherein the carboxylic acid-containing compound is a dicarboxylic acid having at least one sulfur atom.
