Claim 0:
1. A one-component thermosetting epoxy resin composition comprising:
a) at least one epoxy resin A having an average of more than one epoxy group per molecule;
b) at least one latent curing agent for epoxy resins B;
c) at least one compound of the formula, , wherein:
substituents R1 and R2 are independently an unsubstituted benzene, a halogenated benzene, alkoxylated benzene, an alkylated benzene or an N derivative of an aniline,
substituent R3 is H or an alkyl group having 1 to 10 carbon atoms,
a weight ratio of the at least one epoxy resin A having an average of more than one epoxy group per molecule to the at least one compound of the formula (III) is 5-800,
the one-component thermosetting epoxy resin composition has a viscosity at 25° C. of 500-3000 Pa*s, and
the one-component thermosetting epoxy resin composition has a percentage rise in viscosity at 25° C. after storage for one week at 60° C. after mixing that is less than 90% of the corresponding percentage rise in viscosity of a one-component thermosetting epoxy resin composition that is the same except not having a compound of formula (III).
