Abstract

Soft feel coating compositions, particularly for plastic substrates, having improved chemical resistance and methods of improving the chemical resistance of soft-feel coatings are provided.

First claim

I claim:

1. A soft feel coating composition comprising:
a) a film forming resin matrix composition which cures to form a soft feel film having a resin matrix Tg of −80° C. to −20° C.;
b) at least one solvent; and
c) a stainless steel platelet shaped pigment having a density 50% to 400% greater than the density of the resin matrix composition, wherein the stainless steel platelet shaped pigment has a flattened profile that imparts chemical resistance to the coating composition.

2. The coating composition of claim 1 , wherein the stainless steel platelet shaped pigment has a density 150% to 400% greater than the density of the resin matrix composition.

3. The coating composition of claim 1 , wherein the stainless steel platelet shaped pigment is 5% to about 25% volume solids with respect to the total composition.

4. The coating composition of claim 3 , wherein the stainless steel platelet shaped pigment is 5% to about 10% volume solids with respect to the total composition.

5. The coating composition of claim 3 , wherein the stainless steel platelet shaped pigment is about 10% to about 15% volume solids with respect to the total composition.

6. The coating composition of claim 3 , further comprising a flattening agent.

7. The coating composition of claim 6 , wherein the flattening agent is about 2 to about 5 weight percent based on the total weight of solids in the coating composition.
