Document Type and Number:
Japanese Patent JP3391067
Kind Code:
B2
Abstract:

PURPOSE: To obtain an epoxy resin composition comprising a specific epoxy resin, a curing agent, and a curing accelerator, giving cured products excellent in appearance, heat resistance and low water absorbability, and useful for electric laminated boards insulating powder coatings, etc.
CONSTITUTION: This resin composition comprises (A) an epoxy resin having a structure in which aromatic groups are bonded to each other through alicyclic hydrocarbon groups each having a cyclohexane ring, a cyclohexene ring, etc., in the skeleton as binding groups and in which the aromatic groups have been substituted with glycidyloxy groups, and having a Gardner color number of ≤10 in a dioxane solution having a non-volatile content of 50wt.%, e.g. an epoxy resin obtained by reacting an epihalohydrin with a phenol resin obtained by reacting an unsaturated cyclic hydrocarbon compound such as vinylcyclohexene with an OH group-containing compound such as a phenolic compound in the presence of an acidic ion exchange resin, (B) a curing agent, and (C) a curing accelerator.
