Abstract: A colorant including a mixture of pigments is disclosed. The pigments have a similar coloration but different resistance to corrosion. The mixing ratio is selected to optimize the corrosion resistance against color brightness, and/or acidic corrosion resistance against alkali corrosion resistance of the colorant.

Abstract: Various methods for forming dyed microspheres are provided. One method includes attaching a hydrophilic dye to chemical groups to form a bubble. The bubble includes the chemical groups surrounding the hydrophilic dye and an aqueous solution. The chemical groups are soluble in aqueous and organic solvents. The method also includes disposing the bubble and a microsphere to be dyed in a solvent such that the bubble is incorporated into the microsphere thereby dyeing the microsphere. Another method includes adsorbing a hydrophilic dye on a surface of a hydrophobic polymer core of a microsphere to be dyed thereby dyeing the microsphere. The method also includes attaching chemical groups to the hydrophilic dye. The chemical groups are soluble in aqueous and organic solvents. The chemical groups attached to the hydrophilic dye form an enclosure surrounding the hydrophilic dye and an aqueous solution.

Abstract: The present invention relates to pure-coloured, readily dispersible iron oxide red pigments having high grinding stability, to a process for preparing them, and to their use.

Abstract: The present invention relates to a high surface area product and its production from solid-containing material, such as waste effluent from a paper-treating plant. The high surface area product comprises calcium carbonate, and is useful as a coefficient of friction control filler for newsprint.

Abstract: Pigments of flake substrate coated with calcium carbonate wherein the surface of the flake substrate is coated with fine particles of calcium carbonate. The pigment may be manufactured by a method where calcium carbonate in fine particles is separated out and coated on the surface of the flaky substrate by the reaction of a calcium salt with a carbonate in a suspension of the flake substrate. It can be used as an extender particularly for cosmetics exhibiting appropriate adhesion to skin, low luster and excellent wrinkle-hiding effect, prevention of unpleasant feel due to perspiration, sebum absorbing property, etc.

Abstract: Proteinaceous polymers having repetitive units from naturally occurring structural proteins are employed as backbones for functionalities for crosslinking to provide strongly adherent tissue adhesive compositions for bonding together separated tissue, and for sealing or filling tissue defects by injecting the compositions into the defects. Particularly, block copolymers having repeating units of elastin and fibroin are employed having lysine substitutions in spaced apart units, where the amino group can be crosslinked using difunctional crosslinking agents such as glutaraldehyde, activated diolefins, diisocyanates, acid anhydrides or diamines. The protein polymer contains at least 40 weight percent of repetitive units of 3 to 30 amino acids, preferably 3 to 15 amino acids, of at least one naturally occurring structural protein and at least two amino acids containing a functional group capable of reacting with the crosslinking agent.

Abstract: The invention concerns an anti-corrosive pigmentary composition characterized in that contains zinc 8-hydroxy-quinolate.
