US 11,899,361 B2 · Kit, composition for forming underlayer film for imprinting, laminate, and production method using the same

Abstract

Provided is a kit including a curable composition for imprinting which contains a polymerizable compound having an aromatic ring and a composition for forming an underlayer film for imprinting which contains a polymer and a solvent, in which the polymer contains at least one kind of specific constitutional unit and has a polymerizable group, a film formed of the composition for forming an underlayer film for imprinting is a solid film at 23° C., and a portion that has a continuous partial structure containing an aromatic ring which is included in the polymerizable compound and accounts for 60% by mass or more of the polymerizable compound is common to a continuous partial structure containing an aromatic ring which is included in a substituent R in a side chain in the polymer. Furthermore, the present invention relates to a composition for forming an underlayer film for imprinting which is used in combination with a curable composition for imprinting; a laminate; a method for producing a laminate; a method for producing a cured product pattern; and a method for manufacturing a circuit board.
