Abstract:
1. A comb-shaped epoxy resin represented by the following formula (1): in the formula (1), X 1 and X 2 may be the same or different and represents a divalent group having a residue selected from a xanthene residue which may have a methyl group or an ethyl group as a substituent, a biphenylene residue which may have a methyl group or an ethyl group as a substituent, a bisphenol residue which may have a methyl group or an ethyl group or a halogen atom as a substituent, a hydrogenated bisphenol residue which may have a methyl group as a substituent, an alkylene residue and a polyoxyalkylene residue, and at least one of them is an aromatic residue and may vary with a repeating unit; Y represents a linear polymer chain composed of at least one of an ethyleneimine structural unit and an N-acylethyleneimine unit, or a polymer chain composed of a polyethyleneimine-polyalkylene ether block unit or a poly N-acylethyleneimine-polyalkylene ether block unit, a number average polymerization degree being within a range from 5 to 2000, and n (number average polymerization degree) represents an integer of 3 to 200.
