Abstract
Provided is an addition condensation product of an aromatic compound and a carbonyl compound. The addition condensation product includes an aromatic compound dimer in which two composition units derived from the aromatic compounds are bonded via one composition unit derived from the carbonyl compound and an aromatic compound multimer in which each of three or more composition units derived from the aromatic compounds is bonded via one composition unit derived from the carbonyl compound. A ratio of the aromatic compound dimer to the aromatic compound multimer is in the range of 1:75 to 1:1,000.
