Stepped substrate coating composition including compound having photocrosslinking group due to unsaturated bond between carbon atoms

Abstract

A stepped substrate coating composition includes: a compound (E) containing partial structures (I) and (II) and a solvent (F). The partial structure (II) contains a hydroxy group generated by an epoxy group and a proton-generating compound reaction; the partial structure (I) is at least one partial structure selected from partial structures of Formula (1-1) to Formula (1-5) or a partial structure combining a partial structure of Formula (1-6) and Formula (1-7) or Formula (1-8); and the partial structure (II) is a partial structure of Formula (2-1) or Formula (2-2). The photocurable stepped substrate coating composition wherein in the compound (E), the epoxy group and the hydroxy group are contained in a molar ratio of 0≤(Epoxy group)/(Hydroxy group)≤0.5 and the partial structure (II) is contained in a molar ratio of 0.01≤(Partial structure (II))/(Partial structure (I)+Partial structure (II))≤0.8.
