摘要:
The present invention relates to a laundry detergent composition comprising a particle comprising hueing agent and clay. The particle can be incorporated into laundry detergent products, such as a laundry detergent powder. The particle exhibits an excellent storage stability profile with very little bleeding of the hueing dye from the particle, exhibits excellent fabric deposition of the hueing dye during a laundering process without causing any spot staining of the fabric, and does not impact the visual appearance of a laundry detergent powder when incorporated therein.

A high-concentration master batch obtained by blending a granulated colorant and a thermoplastic resin, which comprises 25 to 100 parts by weight of a nigrosine dye in the granulated colorant per 100 parts by weight of the thermoplastic resin. A colored composition comprising a granulated colorant or high-concentration master batch and a thermoplastic resin or thermoplastic elastomer.
摘要:
The present invention relates to a method of producing a granular formulation of colorants soluble in plastics, which method comprises suspending in water a filter cake obtained from preparation of the colorant, adding thereto from 0.1 to 5.0% by weight, calculated with respect to the weight of colorant, of a polyvinylpyrrolidone and, where appropriate, further adjuvants, and then drying the aqueous suspension to form granules, to the granular formulations obtainable according to that method, and to the use thereof in the production of colored plastics or colored polymeric particles.
摘要:
Pigment granules having an average particle size from 50 to 5000 μm and a BET surface area ≦15 m2/g, including as essential constituents (A) from 60 to 90% by weight of at least one pigment and (B) from 10 to 40% by weight of at least one nonionic surface-active additive based on polyethers, are prepared and used for pigmenting macromolecular organic and inorganic materials.
摘要:
The present invention relates to a method of producing a granular formulation of colorants soluble in plastics, which method comprises suspending in water a filter cake obtained from preparation of the colorant, adding thereto from 0.1 to 5.0% by weight, calculated with respect to the weight of colorant, of a polyvinylpyrrolidone or of a sodium lauryl sulfate and, where appropriate, further adjuvants, and then drying the aqueous suspension to form granules, to the granular formulations obtainable according to that method, and to the use thereof in the production of colored plastics or colored polymeric particles.
摘要:
The present invention relates to a colored porous material comprising in its pores an effectively coloring amount of an organic pigment which is obtainable by fragmenting a meltable or solvent-soluble pigment precursor, and to a process for its preparation. The present invention also relates to the use of the instant colored porous material powders as pigments for high molecular weight organic materials.
摘要:
The invention relates to a process for the preparation of pigment granules, which comprises adding a wax or a waxy polymer to an organic pigment during the finish in an organic or aqueous organic medium and spray-drying the aqueous suspension obtained after removal of the organic solvent by steam distillation or washing out with water.
摘要:
To prepare storage-stable, low-dusting dyestuff granules which are readily soluble in plastics, a suspension of the dyestuff containing 0.1-5% by weight of a polyglycol are dried while being granulated.
摘要:
The present invention concerns a process for preparing a treated blend which contains pigment material dispersed in a continuous phase of water and a polyester material. The invention also concerns compositions prepared from such process. The polyester material of the treated blend is linear, contains a sulfomonomer, and has an average particle size of less than 1 .mu.m.
