ANTISAPSTAIN COMPOSITIONS COMPRISING A HALOALKYNYL COMPOUND, AN AZOLE AND AN UNSATURATED ACID

摘要

The present invention provides antisapstain compositions comprising a haloalkynyl compound, an azole and an unsaturated carboxylic or sulphonic acid. The compositions of the invention are surprisingly effective at protecting wood and other cellulosic substrates, in particular at providing antisapstain activity. The invention also provides methods for treating wood and other cellulosic substrates with said compositions.
