Abstract

A pigment, including a magnetizable reflector layer including an intermetallic compound, wherein the intermetallic compound is a crystal structure of at least two different elemental metals chemically bonded together is disclosed. A pigment, including a semi-transparent absorber layer including an intermetallic compound, wherein the intermetallic compound is a crystal structure of at least two different elemental metals chemically bonded together is disclosed. A method of making the pigment is also disclosed.

First claim

What is claimed is:

1. A pigment, comprising:
a magnetizable reflector layer including an intermetallic compound, wherein the intermetallic compound is a crystal structure of at least two different elemental metals chemically bonded together,
wherein the intermetallic compound is selected from the group consisting of CoAs 2 , NiSb, ZrNi, Zr 2 Ni, Zr 3 Fe, TbAl, Tb 2 Al, Fe x Si y Al z (x=85%, y=9%, z=6%), Tb x Dy 1-x Fe 2 (x˜0.3), AlGd, AlGd 2 , TbPtGa, La 2 Co 17-x Ta x in which x is 0.5 or 0.6, HoCo 2 B 2 C, GdNi 2 B 2 C, ErCo 2 B 2 C, and (Y 1-x Gd x )Ni 2 B 2 C; and
wherein the pigment has a structure of: first absorber layer/dielectric layer/the magnetizable reflector layer including an intermetallic compound/dielectric layer/second absorber layer.

2. The pigment of claim 1 , wherein the intermetallic compound is selected from the group consisting of CoAs 2 , NiSb, ZrNi, Zr 2 Ni, Zr 3 Fe, Tb x Dy 1-x Fe 2 (x˜0.3), La 2 Co 17-x Ta x in which x is 0.5 or 0.6, HoCo 2 B 2 C, GdNi 2 B 2 C, ErCo 2 B 2 C, and (Y 1-x Gd x )Ni 2 B 2 C.

3. The pigment of claim 1 , wherein the intermetallic compound is a compound chosen from TbPtGa, and La 2 Co 17-x Ta x , where x=0.5 or 0.6.

4. The pigment of claim 1 , wherein the intermetallic compound is a compound chosen from HoCo 2 B 2 C, GdNi 2 B 2 C, and ErCo 2 B 2 C.

5. The pigment of claim 1 , wherein the intermetallic compound is (Y 1-x Gd x )Ni 2 B 2 C.

6. The pigment of claim 1 , further comprising, at least one dielectric layer.

7. The pigment of claim 1 , further comprising, at least one absorber layer.

8. The pigment of claim 1 , wherein the first absorber layer is a semi-transparent absorber layer including an intermetallic compound and wherein the second absorber layer is a semi-transparent absorber layer including an intermetallic compound.

9. A composition comprising the pigment of claim 1 dispersed in a liquid medium.

10. A pigment, comprising:
a semi-transparent absorber layer including an intermetallic compound, wherein the intermetallic compound is a crystal structure of at least two different elemental metals chemically bonded together;
wherein the intermetallic compound is selected from the group consisting of CoAs 2 , NiSb, Cu 3 As, ZrNi, Zr 2 Ni, Zr 3 Fe, TiZn, Ti 2 Zn, TiZn 2 , TbAl, Tb 2 Al, Tb x Dy 1-x Fe 2 (x˜0.3), TbPtGa, La 2 Co 17-x Ta x in which x is 0.5 or 0.6, HoCo 2 B 2 C, GdNi 2 B 2 C, ErCo 2 B 2 C, and (Y 1-x Gd x )Ni 2 B 2 C,
wherein the pigment has a structure of: semi-transparent absorber layer including an intermetallic compound/dielectric layer/reflector layer/dielectric layer/semi-transparent absorber layer including an intermetallic compound.

11. The pigment of claim 10 , wherein the intermetallic compound is selected from the group consisting of CoAs 2 , NiSb, Cu 3 As, ZrNi, Zr 2 Ni, Zr 3 Fe, TiZn, Ti 2 Zn, TiZn 2 , TbAl, Tb 2 Al, Tb x Dy 1-x Fe 2 (x˜0.3), La 2 Co 17-x Ta x in which x is 0.5 or 0.6, HoCo 2 B 2 C, GdNi 2 B 2 C, ErCo 2 B 2 C, and (Y 1-x Gd x )Ni 2 B 2 C.

12. The pigment of claim 10 , wherein the intermetallic compound is a two-component binary intermetallic compound chosen from any of the two-component compounds recited in claim 10 .

13. A composition comprising the pigment of claim 10 dispersed in a liquid medium.
