Estimating the term…
A resin composition for an aqueous coating material that includes a propylene-butene resin component and/or propylene-ethylene-butene resin component (A), and a (meth)acrylic resin component (B), wherein the mass ratio between the propylene-butene resin component and/or propylene-ethylene-butene resin component (A) and the (meth)acrylic resin component (B) is within a range from 15:85 to 75:25. Also disclosed are a method for producing such a resin composition and an aqueous coating material. The present invention is able to provide a resin composition for an aqueous coating material that is useful as a binder within an aqueous coating material that uses no organic solvents or chlorine compounds, and yet exhibits excellent adhesion to polyolefin-based resins and is capable of forming a coating film that is resistant to discoloration and exhibits favorable resistance to the oils contained within gasoline, cosmetic products and foodstuffs and the like, and is also able to provide a method for producing the resin composition and an aqueous coating material that uses the resin composition.
A resin composition for an aqueous coating material, comprising a propylene-butene resin component and/or propylene-ethylene-butene resin component (A), and a (meth)acrylic resin component (B), wherein said (meth)acrylic resin component (B) is polyolefin-modified (meth)acrylic resin particles (B-2), which are composed of a polymer obtained by swelling propylene-ethylene-butene resin particles with a monomer raw material liquid, and subsequently polymerizing the monomer raw material liquid, wherein the monomer raw material liquid comprises styrene at 10 to 20% by mass within 100% by mass of the monomer raw material liquid, and a mass ratio between said propylene-butene resin component and/or propylene-ethylene-butene resin component (A) and said (meth)acrylic resin component (B) is within a range from 30:70 to 60:40.
