    摘要: There is provided an epoxy resin composition in a liquid or solid state having excellent solubility and having high preservation stability. A modified epoxy resin composition characterized by comprising: Compound A containing tris-(2,3-epoxypropyl)-isocyanurate having 1 to 3 glycidyl group(s) in a molecule substituted with a functional group(s) of Formula (1): in which R 1 and R 2 are each independently an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an aralkyl group, a heterocyclic group; or a halogenated derivative, an aminated derivative, or a nitrated derivative of these groups; and Compound B containing tris-(2,3-epoxypropyl)-isocyanurate, wherein tris-(2,3-epoxypropyl)-isocyanurate of Compound A before the substitution and tris-(2,3-epoxypropyl)-isocyanurate of Compound B comprises 2% by mass to 15% by mass of ²-type tris-(2,3-epoxypropyl)-isocyanurate and a remaining percentage of ±-type tris-(2,3-epoxypropyl)-isocyanurate based on a total mass of Compound A before the substitution and Compound B.
