1. A resin composition, comprising a main polymer and a crosslinking agent, wherein the crosslinking agent is represented by Formula (A), (B), or (C):
(HS)n1-L1-Ar1-L1-(SH)n1  (A)
(HS)n1-Ar1-(SH)n1  (B)
(HS)n1-Ar1-L1-(SH)n1  (C)
wherein, Ar1 is an aromatic group containing 6 to 50 ring atoms, and each L1 is independently selected from one or more of a C1 to C50 alkylene, or a dynamic covalent bond group;
each n1 is independently selected from integers from 1 to 3; and
a structural unit of the main polymer contains a structure represented by Formula (1), a structure represented by Formula (1A), a structure represented by Formula (1B), and/or a structure represented by Formula (1C), and the main polymer contains no aromatic group:

OG Complex Work Unit Chemistry
wherein:
R1 and R2 each are one independently selected from a single bond, a substituted or unsubstituted C1 to C15 alkylene, a substituted or unsubstituted C2 to C15 alkenylene, or a substituted or unsubstituted C2 to C15 alkyl ether group;
L2 is a substituted or unsubstituted C1 to C20 hydrocarbon group, and the hydrocarbon group contains an olefinic bond and/or an acetylenic bond; and
* is a linking site.
