Abstract:
A dispersing stabilizer comprising a partially hydrolyzed polyvinyl alcohol resinhaving a degree of hydrolysis of 65 to 85% by mole, and containing 0.1 to 10% by mole of an oxyalkylene group, in its side chains, represented by the formula (1): ##STR20## wherein R.sup.1 is hydrogen atom or an alkyl group, R.sup.2 is an alkyl group, X is hydrogen atom, an alkyl group, an alkylamide group or an alkyl ester group, and n is a positive number, and0.2 to 10% by mole of an anionic hydrophilic group, in its side chains and/or terminal;wherein the average degree of polymerization (of said partially hydrolyzed polyvinyl alcohol resin is 400 to 2,000, and the average degree of polymerization (and the content ""a"" (% by mole) of said anionic hydrophilic group satisfy the relationship represented by the equation (2):0.1<PA.times.a.times.10.sup.-2 <2 (2).2.
