US Patent:

6440208, Aug 27, 2002

Filed:

Nov 6, 2000

Appl. No.:

09/707229

Inventors:

James D. Christie - Yonkers NY
Daniel S. Fuller - Beacon NY
Curtis J. Zimmermann - Cold Spring NY

Assignee:

Engelhard Corporation - NJ

International Classification:

C09C 100

US Classification:

106415, 106403, 106404, 106417, 106419, 106431, 106440, 106461, 106480, 106481, 106482

Abstract:

A color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with copper, zinc, an alloy of copper, or an alloy of zinc first layer which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides an optically variable reflection of light impinging thereon and a third layer encapsulating the second layer and being selectively transparent to light directed thereon.

Abstract:

A precious metal color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with a first layer selected from the group consisting of silver, gold, platinum, palladium, rhodium, ruthenium, osmium, iridium and the alloys thereof, which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides an optically variable reflection of light impinging thereon and a third layer encapsulating the second layer and being selectively transparent to light directed thereon.

Filed:

May 26, 2000

Appl. No.:

9/579958

Inventors:

James D. Christie - Yonkers NY
William C. Howard - Yorktown Heights NY

Assignee:

Engelhard Corporation - Iselin NJ

International Classification:

A61K 7021

US Classification:

424 63

Abstract:

A lamellar particle is coated with an amorphous metal oxide hydrated gel which is then converted into a hydrophobic metal hydroxide-organic composite polymer film. The resulting product can be combined with a powdery film-forming polymer to produce a film-forming composition which can be applied by electrostatic coating. It also has significantly enhanced performance in plastic masterbatching, hydrophobic cosmetic formulations, and liquid paints and numerous other applications where a hydrophobic pigment is advantageous.
