摘要

A composition for preventing creeping of a flux for soldering, which is free from a problem from the viewpoint of the global environment or working environment is provided. The composition comprising a polymer (A) containing the polymer units (a<1>) derived from an unsaturated ester containing a polyfluoroalkyl group and the polymer units (b<1>) derived from a compound containing a silicon atom and an unsaturated group, and an aqueous medium (B), further optionally including a fluorine type surfactant (C).
