The present invention provides a novel metal alkoxide having excellent hydrolysis resistance, and a crosslinking agent composition for aqueous resin and an aqueous resin composition each using the same. A metal alkoxide represented by the following formula (1-1), (1-2), or (1-3) and having a mass average molecular weight of 800 to 8,500 is used:Ti(OA)&#x2003;&#x2003;(1-1)Zr(OA)&#x2003;&#x2003;(1-2)Al(OA)&#x2003;&#x2003;(1-3)

Metal alkoxide, and aqueous resin crosslinking composition and aqueous resin composition which use same

The present invention provides an epoxy resin composition, which is improved in terms of storage stability without deteriorating the characteristics of a cured resin, and is also superior in handling property, by using a curing accelerator having higher latency. The epoxy resin composition of the present invention comprises an epoxy resin, a curing agent, and a curing accelerator, wherein the curing accelerator is a reaction product between a carbodiimide compound and an imidazole compound, and is contained in an amount of 0.1 to 5 parts by mass with respect to 100 parts by mass of the epoxy resin.
