Claim Text:
1. A method for producing an acrylic polymer, the method comprising: polymerizing an acrylic monomer mixture (a) to obtain a polymer (A); and polymerizing, an acrylic monomer mixture (b) in a dispersion comprising, the polymer (A), wherein the acrylic monomer mixture (a) comprises a monomer having a hydroxyl group, the acrylic monomer mixture (b) comprises a monomer having an acetoacetyl group or a blocked isocyanate group, and a solubility parameter (SA) of the polymer (A) is different from a solubility parameter (SB) of a polymer (B) obtained by polymerizing the acrylic monomer mixture (b) wherein the acrylic monomer mixture (b) comprises the monomer having an acetoacetyl group or a blocked isocyanate group in an amount of 0.7 to 15 mol % based on 100 mol % of the acrylic monomer mixture (b), wherein the acrylic monomer mixture (a) comprises the monomer having a hydroxyl group in an amount of 0.1 to 15 mol % based on 100 mol % of the acrylic monomer mixture (a), and wherein the acrylic monomer mixture (a) further comprises methyl methacrylate, butyl methacrylate, or a combination thereof in a total amount of 55 mol % or greater based on 100 mole of the acrylic monomer mixture (a).
