1. A resin composition comprising:
a resin having a first group capable of forming at least two hydrogen bonds; and
a photoisomerization compound having a second group capable of forming at least two hydrogen bonds complementarily with the first group and having a moiety that is reversibly isomerized by light,
wherein the first group and the second group are each independently a residue of any one compound selected from the group consisting of adenine, guanine, cytosine, thymine, uracil, urea, thiourea, melamine, cyanuric acid, barbituric acid, a 2,6-diacylaminopyridine, 2,6-diacetylaminopyridine, 4,6-diamino-2 pyrimidinone, 2-amino-4,6-pyrimidinedinone, 2,4,6-triaminopyrimidine, phthalimide, 2,6-diamino-1,3,5-triazine, 2-ureido-4-amino-1,3,5-triazine, and 2-ureido-4 pyrimidinone,
the resin contains a structure represented by general formula (1):
-M-B1
wherein
M represents a linking group, and
B1 represents the first group capable of forming at least two hydrogen bonds, and
the photoisomerization compound is a compound represented by general formula (2):
