Document Type and Number:

WIPO Patent Application WO/2017/138608

Kind Code:

A1

Abstract:

Provided are an additive and a surface treatment agent with which it is possible to suppress the agglutination of latex particles contained in a reagent for a latex agglutination reaction during storage of the reagent, irrespective of whether a synthetic polymer is used as an active component. An additive for addition to latex particles used in a reagent for a latex agglutination reaction, wherein: the latex particles have not undergone a blocking process; hydrophilic repeating units (A) constitute over 60% by mass and no more than than 99% by mass of all repeating units in the additive, and hydrophobic repeating units (B) constitute at least 1% by mass and less than 40% by mass of all repeating units in the additive; and the additive includes a polymer having a weight-average molecular weight of 3,000 or higher.
