Abstract

This invention relates to a wax composition comprising a plurality of fatty acid amide compounds having the Formula (I):where R1, R2, n1, n2, m1, and m2 are as described herein. This invention also relates to a wax composition comprising:a) one or more fatty acid amide compounds having the Formula (II):andb) one or more fatty acid amide compounds having the Formula (III):where R1, R2, n1, and n2 are as described herein. This invention also relates to a fatty acid amide compound having the Formula (I) and a process for preparing a compound of Formula (I).

First claim

What is claimed:

1. A wax composition comprising:
a) one or more fatty acid amide compounds having the Formula (II):

and
b) one or more fatty acid amide compounds having the Formula (III):

wherein:
R 1 is each independently a substituted or unsubstituted C 3 to C 50 alkyl or substituted or unsubstituted aryl;
R 2 is each independently substituted or unsubstituted C 3 to C 50 alkyl, substituted or unsubstituted arylalkyl, substituted or unsubstituted arylalkenyl, or substituted or unsubstituted aryl;
n 1 is an integer from 0 to 10; and
n 2 is an integer from 1 to 20;

wherein component a) and component b) are blended together.

2. The wax composition of claim 1 further comprising:
c) one or more fatty acid monoamide compounds having the Formula (IV):

wherein R 1 is a substituted or unsubstituted C 3 to C 50 alkyl or aryl; and n 1 is an integer from 0 to 10.

3. The wax composition of claim 1 wherein R 1 is each independently a substituted or unsubstituted C 12 to C 50 alkyl or substituted or unsubstituted aryl; R 2 is each independently substituted or unsubstituted C 12 to C 50 alkyl, substituted or unsubstituted arylalkyl, substituted or unsubstituted arylalkenyl, or substituted or unsubstituted aryl; and n 2 is an integer from 6 to 20.

4. The wax composition of claim 1 wherein R 1 is each independently an unsubstituted C 3 to C 28 alkyl, and R 2 is each independently substituted or unsubstituted C 3 to C 28 alkyl or substituted or unsubstituted arylalkenyl.

5. The wax composition of claim 1 wherein R 1 is each independently an unsubstituted C 12 to C 28 alkyl, and R 2 is each independently substituted or unsubstituted C 12 to C 28 alkyl or substituted or unsubstituted arylalkenyl.

6. The wax composition of claim 2 , wherein R 1 is a substituted or unsubstituted C 12 to C 50 alkyl or aryl.

7. The wax composition of claim 1 , wherein the component a) ranges from 20 wt % to 90 wt % of the wax composition, and the component b) ranges from 10 wt % to 80 wt % of the wax composition.

8. The wax composition of claim 1 , wherein the component a) ranges from 60 wt % to 90 wt % of the wax composition, and the component b) ranges from 10 wt % to 40 wt % of the wax composition.

9. The wax composition of claim 1 , wherein the wax composition has a melting point ranging from 50° C. to 200° C.

10. The wax composition of claim 1 , wherein the wax composition has a melting point ranging from 80° C. to 200° C.

11. The wax composition of claim 1 , wherein the wax composition has a penetration hardness of 3.0 mm or below, measured by a standard needle penetration test according to the ASTM D1321 standard, with a 100 g cone, and the penetration being conducted for 5 seconds at 23° C.

12. The wax composition of claim 1 , wherein the wax composition has a penetration hardness of 0.5 mm or below, measured by a standard needle penetration test according to the ASTM D1321 standard, with a 100 g cone, and the penetration being conducted for 5 seconds at 23° C.

13. The wax composition of claim 1 , further comprising one or more natural waxes.

14. A coated material comprising:
a substrate and
the wax composition of claim 1 coated on said substrate.
