An aqueous, bubble forming composition is provided that contains glitter, wherein the glitter is strongly both lipophilic and hydrophilic and therefore able to preferentially release from the contact surface of the bubble forming toy while maintaining the structural integrity of the bubbles.

The present invention provides a glitter pigment, including: a glass flake; a titanium oxide layer formed over the glass flake; and fine gold particles deposited on the titanium oxide layer, wherein the fine gold particles include fine gold particles P2 having a particle diameter of 20 nm or more and less than 50 nm, and in a square region 2 m on a side on a surface of the titanium oxide layer on which the fine gold particles are deposited, the number of the fine gold particles P2 is 9 or more and less than 100 and an average of distances between the fine gold particles P2 is 130 nm or more and less than 500 nm, each of the distances being a distance from one of the fine gold particles P2 to another fine gold particle P2 nearest to the one.

A pigment including a pre-flake; and a coating of nanoparticles present on a surface of the pre-flake, wherein the nanoparticles can be present in the coating in an amount greater than about 40% by volume is disclosed. A method of making a pigment is also disclosed.

Provided are thin leaf-like indium particles having a first peak and a second peak at a greater particle diameter than a particle diameter at which the first peak appears in a volume-based particle size distribution representing a relationship between particle diameters of indium particles and ratios by volume of the indium particles at the particle diameters, wherein a volume V1 of the indium particles at the first peak and a volume V2 of the indium particles at the second peak satisfy a formula (V1/V2)10025%.

A golden effect pigment comprising an optionally passivated platelet-shaped metallic substrate and an iron oxide layer, wherein the effect pigment has a hue angle h.sub.15 of 67h.sub.1578 and a chroma C*.sub.15 of 90 is provided. Further, a golden effect pigment comprising an optionally passivated platelet-shaped metallic substrate and an iron oxide layer, wherein the effect pigment has a hue angle h.sub.15 of 67h.sub.1578 and a chroma C*.sub.45 of 50 is provided. The golden effect pigments are highly chromatic and suitable for coloring a coating composition such as a paint, a printing ink, an ink, a varnish, plastics, a fiber, a film or a cosmetic preparation, preferably an automotive, an architectural or an industrial coating composition

The present invention relates to alumina flakes having a defined thickness and particle size distribution and to their use in varnishes, paints, automotive coatings, printing inks, masterbatches, plastics and cosmetic formulations and as substrate for effect pigments.

The invention relates to coated effect pigments, wherein the coating comprises a binder which is suitable for powder paints. They comprise a crystalline and an amorphous fraction which is determined by C.sup.13 NMR MAS relaxation measurements, the relaxation of the .sup.13C cores being fitted as a biexponential relaxation according to the formula (II) and the degree of crystallinity c being in a range between 40 to 85%, and relaxation having a short average relaxation time T.sub.1.sup.S and a long average relaxation time T.sub.1.sup.I, and T.sub.1.sup.I being in a range of from 65 to 130 s. The effect pigments coated according to the invention have at least one endothermic peak with a maximum from a range of T.sub.max=100 to 150 C. and an enthalpy H associated with said peak from a range of 15 J/g to 80 J/g in DSC at a feed speed of 5 C./min, the enthalpy being calculated relative to the amount of the binder. The binders are applied to the effect pigment by way of spontaneous precipitation.
