Disclosed are pigment powders containing only coated BiOCl flakes, which flakes area) BiOCl flakes having a coating containing yellow iron oxide FeO*xHO, optionally a colorant, optionally an adjuvant, and optionally SiO, b) BiOCl flakes having a coating containing SiO, optionally a colorant, and optionally an adjuvant, c) BiOCl flakes having a coating containing a colorant, SiO, optionally yellow iron oxide FeO*xHO, and optionally an adjuvant, or d) BiOCl flakes having a coating containing FeOand optionally SiO, to a process for the preparation of the pigment powders, and to the use thereof especially in cosmetic formulations.

Pigment powders

Disclosed are pigment mixtures containing at least two components, where component A contains bismuth oxychloride (BiOCl) or boron nitride (BN) and component B contains synthetic flakes treated with at least one metal soap or mineral flakes treated with at least one metal soap and to the use thereof especially in cosmetic formulations.

Pigment mixtures

A method of producing mixtures of interference pigments having special effects comprises mixing at least one large particle size interference pigment with at least one normal size interference pigment of predetermined colors and in proportions desired to obtain a unique effect.

Special effects with mixtures of interference pigments

The present invention generally relates to a method of laser-marking. The method can include exposing a precursor to a laser creating a mark. The precursor can include a polymer or plastic loaded with a laser-marking additive in an amount of or greater than about 1 wt. %. The additive can include:

Method for laser-marking and an article marked by such method

A composite sheet, and a process of making the same, including cured modified urea formaldehyde reinforced by glass fibers. The modifier is an acrylonitrile-butadiene-styrene copolymer. A roofing shingle, formed by coating the composite sheet with filled asphalt, represents a major application of the composite sheet.

Shingle and mat tensile strength with urea formaldehyde resin modifier

Enhanced tear strength asphalt roofing composites, e.g., roofing shingles which can meet the current ASTM D-3462 standard for tear strength, include an adhesion modifier treated, preferably a polysiloxane treated, glass fiber mat.

Asphalt roofing composite including adhesion modifier-treated glass fiber mat

A coated fiber mat of improved tear strength upon dividing pieces of the coated mat and the coating is provided. The coated mat is a cured, non-woven mat including a mixture of fibers having different fiber lengths. The fibers contain a polysiloxane compound and are fixedly distributed in a binder.

Shingle tear strength with fiber mixture of different fibers

The invention relates to a coated fiber mat of improved tear strength upon dividing pieces of the coated mat and the coating which comprises a cured, non-woven, fiber glass mat containing a polysiloxane wherein the fibers are fixedly distributed in a formaldehyde type binder containing a binder modifier which is a crosslinked styrene/acrylic polymer, and to a process for the preparation of the mat.
