  In the production of a glass substrate for magnetic disks, in a step of polishing a main surface of a circular glass plate, roll-off is reduced without reducing the polishing rate. The process comprises a step of polishing a main surface of a circular glass plate by using an acidic polishing fluid containing colloidal silica or fumed silica, and a water-soluble polymer having at least one member selected from a group consisting of a carboxylic acid group, a carboxylate group, a sulfonic acid group and a sulfonate group, bonded to its main chain, or an acidic polishing fluid containing 100 parts by mass of colloidal silica or fumed silica, and from 0.02 to 0.1 part by mass of a surfactant having a sulfonic acid group.

  Compositions are disclosed that impart one or more durable hair styling benefits. The durable styling compositions comprise at least a first compound having anhydride, diacid, diester, or half-acid/half-ester functionality, and a second compound having at least one amine moiety or hydroxyl functional group. In one embodiment the durable styling composition takes the form of a leave-in product. The durable styling compositions are heat-activated, which may be accomplished through the use of a heated styling tool like a flat-iron, curling iron, and/or hair dryer. The benefits include shine, conditioning, softness, defrizzing, and improved hair alignment, and endure for up to 5 wash cycles or more without having to reapply the durable styling composition nor heat.

  [EN] A pigment dispersion comprising a colour pigment represented by formula (I) wherein, R1 to R10 are independently selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, - CF₃ , -COOH, -COOCH₃; -SO₂NH-C₆H₅, -CONH-C₆H₅, -CONH-C₆H₅-CONH₂ and -CONH₂; and a polymeric dispersant having via a linking group covalently linked to its polymeric backbone at least one pending chromophore group which has a molecular weight smaller than 95% of the molecular weight of said colour pigment. The pigment dispersion can be advantageously used in inkjet inks.
  [FR] La présente invention concerne une dispersion de pigment qui comprend un pigment de couleur représenté par la formule (I) dans laquelle les éléments R1 à R10 sont indépendamment sélectionnés dans le groupe formé par hydrogène, un atome d'halogène, un groupe méthyle, un groupe éthyle, un groupe méthoxy, un groupe éthoxy, - CF₃, -COOH, -COOCH₃; -SO₂NH-C₆H₅, -CONH-C₆H₅, -CONH-C₆H₅-CONH₂ et -CONH₂; et un dispersant polymère comprenant par l'intermédiaire d'un groupe de liaison lié par covalence à son squelette polymère, au moins un groupe chromophore pendant qui présente un poids moléculaire inférieur à 95 % du poids moléculaire du pigment de couleur. Cette dispersion de pigment peut être avantageusement utilisée dans des encres destinées à des imprimantes à jet d'encre. Formule (I)
