Härtbare Emulsion und diese enthaltendes Beschichtungsmaterial

摘要

A curable emulsion is prepared by copolymerizing the following radical-polymerizable components (a) to (d) in the presence of a pH buffering agent in an aqueous medium: (a) an alkoxysilane containing a radical-polymerizable group; (b) a vinyl monomer copolymerizable with component (a); (c) the following (c-1) or (c-2): (c-1) being a polyester or a polyalkylene oxide having an average condensation degree of not less than 3 and having a radical-polymerizable group linked to one end of the molecule, the radical-polymerizable group being copolymerizable with component (a); and (c-2) being a macromonomer comprising a vinyl polymer or a polysiloxane having a radical-polymerizable group which is copolymerizable with component (a) and linked to one end of the vinyl polymer or polysiloxane molecule, the number average molecular weight of the macromonomer being 1,000 to 30,000; and (d) a radical-polymerizable anionic or cationic surfactant represented by the following general formula (I): Z-(AO) n -Y```(I) wherein Z represents a structural unit containing a radical-polymerizable group copolymerizable with component (a); AO represents an oxyalkylene group; n represents an integer of 2 or more; and Y represents an ion-dissociable group.
