A color effect material is described as composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with a highly reflective layer which acts as a reflector to light directed thereon and a spacer pigment layer which is selectively transparent to light directed thereon.

Color effect materials and production thereof

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.

Alloy color effect materials and production thereof

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.

Precious metal color effect materials and production thereof

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.

Bonded metal hydroxide-organic composite polymer films on particulate substrates

Colored lustrous pigments of superior quality are prepared by dry blending a metal oxide-coated mica nacreous pigment and a colorant lake with a blend adjuvant. The resulting blend exhibits a well dispersed, stable coloration, increased hydrophobicity and is particularly useful in cosmetic applications.

Blended nacreous pigments, colorants and adjuvants

A support for the total weight of an instrument while playing in both sitting and standing positions having a base with foldable support arms, a height adjustable vertical tube and rod combination mounted in base's center. Two lengths of vertical tubes provide sitting and standing capability. Rod is bent at its top and attaches at right angle to a Y shaped instrument mount, a post equidistant to the inner sides of mount and in mount's center rests instrument's bell thereby securely supporting all instrument weight without attachments or insertions into instrument.
