Solubilizer and Composition Containing Same

摘要

The present invention provides a solubilizing agent that can give solubility or dispersibility in resins to copper-containing phosphorus compounds, and a composition containing the solubilizing agent. The solubilizing agent of the invention comprises a compound represented by the following general formula (100) having a main chain with an oxyalkylene unit. [wherein R¹¹¹ represents hydrogen or a b-valent organic group, R¹¹² represents C2-4 alkylene, R¹¹³ represents hydrogen, alkyl, aryl or acyl, a represents an integer of 1-50 and b represents an integer of 1-4.]
