Abstract
The present invention aims to provide a polymer capable of well dispersing hydrophobic particles. The present invention relates to a hydrophobic group-containing copolymer including a structural unit (A) derived from a hydrophobic group-containing monomer that is represented by the formula (1) and a structural unit (B) derived from a carboxylic acid-based monomer. The proportion of the structural unit (A) is from 16% by mass or more to 50% by mass or less based on 100% by mass of the structural units derived from all monomers constituting the copolymer, and the copolymer has a weight average molecular weight of 10,000 to 1,000,000.
