Abstract: Abrasive articles containing solid abrasive particles (A) selected from the group consisting of inorganic particles, organic particles and inorganic-organic hybrid particles (a1) having an average primary particle size of from 1 to 500 nm as determined by laser light diffraction and having electron donor groups (a2) chemically bonded to their surface are provided. The said solid abrasive particles (A) are distributed throughout or on top of or throughout and on top of a solid matrix (B). A method for manufacturing abrasive articles and a method for processing substrates useful for fabricating electrical and optical devices are provided. The said methods make use of the said abrasive articles.

Abstract: A bismuth vanadate pigment is provided which pigment is doped with a combination of Mg, Al and P and optionally an element E, wherein the molar ratios of the Bi, V, Mg, Al, P and E correspond to a formula Bi Mga Alb Ec Vd Pe Of  (I) wherein E is selected from the group consisting of Be, Ca, Sr, Ba, Zr, Mo, Ce and a combination thereof; 0.001≦̸0.2; 0.001≦̸b≦̸0.2; 0≦̸c≦̸1.7; 0.5≦̸d≦̸2.3; 0.001≦̸e≦̸0.5; and f denotes the number of oxygen atoms for satisfying the valence requirements of the cations. The pigment may be used as colorant in various applications, especially in coloring high molecular weight organic material, for example, coating compositions, paints, printing inks, liquid inks, plastics, films, fibers, or glazes for ceramics or glass.
