<p><P>PROBLEM TO BE SOLVED: To provide a highly purified esterified material wherein impurities exerting adverse influence on dispersion performance and the like of a final product are extremely reduced and which is obtained by reaction of alcohol and (meth)acrylic acid. <P>SOLUTION: The esterified material whose polymer content is 2.0 surface% or less is represented by general formula (1) (wherein, R<SP>1</SP>denotes a 1-30C hydrocarbon group, R<SP>2</SP>O denotes a 2-18C oxyalkylene group, wherein recurring units of respective R<SP>2</SP>O may be equal to or different from each other and the recurring units of the respective R<SP>2</SP>O may be added in a block type or in a random type when the R<SP>2</SP>O are formed in a form of two or more mixtures, R<SP>3</SP>denotes a hydrogen atom or a methyl group and n denotes an average added mole number of the oxyalkylene group and a number of 0 to 300). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
