Abstract
Described herein is a waterborne emulsion, a method for making the waterborne emulsion, and an application of the waterborne emulsion as a binder for inks. The waterborne emulsion includes an acidic polymer stabilizer and a base polymer. The ink made using the waterborne emulsion shows excellent alcohol tolerance and wet wrinkle resistance.
Claims20
A waterborne emulsion comprising:
- A) an acidic polymer stabilizer with a weight average molecular weight (Mw) in a range of 4,000 to 18,000, an acid value (AV) in a range of 60 to 200 and an oxygen content of at least 15 wt %;
- and
- B) a base polymer with an oxygen content of at least 12 wt %,
- wherein, optionally, the acidic polymer stabilizer is present in a range of 20 wt % to 70 wt %, based on a total dry weight of the waterborne emulsion, and a theoretical acid value (TAV) of the waterborne emulsion is in a range of 15 to 60.
