Title:
POLYURETHANE RESIN COMPOSITION AQUEOUS DISPERSION AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2018053245
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyurethane resin composition aqueous dispersion in which the stability of a block isocyanate group is excellent, and, both adhesion and the mechanical physical properties of a dry film are excellent.SOLUTION: Provided is a polyurethane resin composition aqueous dispersion comprising water and a polyurethane resin composition (K). The polyurethane resin composition (K) includes: polyurethane resin (U) containing polyol (a), polyisocyanate (b), a compound (c) having an ionic polar group and two active hydrogen atoms and a chain extender (d) as essential structural monomers; polyisocyanate (I) in which the content of an oxyethylene group is 10 wt.% or lower; and a blocked polyisocyanate compound (J) as a reactant with an isocyanate blocking agent, and including the grains of the polyurethane resin composition (K).SELECTED DRAWING: None
