Title:

STAINPROOFING AGENT

Document Type and Number:

WIPO Patent Application WO/2011/105254

Kind Code:

A1

Abstract:

A stainproofing agent which contains a polyorganosiloxane that has silicon-bonded functional groups (functional groups bonded to silicon atoms) and that has a number-average molecular weight of 3,000 to 500,000 in terms of standard polystyrene as determined by gel permeation chromatography and a silicon-bonded functional group equivalent (a number-average molecular weight per mol of the silicon-bonded functional groups) of on average 3,000 to 500,000. Thus, the stainproofing agent is prepared using a modified silicone having functional groups. The stainproofing agent can effectively inhibit or reduce, even under high -temperature conditions, the adhesion of sticky substances to the surface of a substrate, and also exhibits excellent stability.
