Abstract
A hyper branched type epoxy resin including a polymerized substance generated from a polyfunctional epoxy compound represented by a formula (I), wherein the polyfunctional epoxy compound represented by the formula (I) includes group A having aromatic hydroxyl group, a carboxyl group or aromatic ring having an amino group, and epoxy containing group B having an epoxy group; wherein R represents an organic group of (n+1) valence, and n represents 2 or 3. A-R—(B)n (I)
Claims8
A hyper-branched type epoxy resin comprising a polymerized substance generated from a polyfunctional epoxy compound represented by a formula (I) as a monomer via a self-polymerization reaction thereof and including plural epoxy groups at a terminal site of the polymerized substance,
- wherein the polyfunctional epoxy compound represented by the formula (I) comprises group A having an aromatic hydroxyl group, a carboxyl group, or an aromatic ring having an amino group, and an epoxy-containing group B having an epoxy group:
- A-R—(B)n (I),
- wherein R represents an organic group of (n+1) valence, and n represents 2 or 3.
