摘要:
The present invention relates to a process for preparing a pigment composition whereby a mixture of an organic pigment and an inorganic filler is subjected to an air jet milling step. The inventive process is an environmentally friendly process which yields pigments having outstanding dispersibility and wetting characteristics when incorporated in plastics, aqueous or solvent based coatings and inks.

摘要:
Disclosed are novel azo dyes of the structureX--N.dbd.N--C'wherein X represents the diazonium component comprising phenyl or a heterocyclic group commonly used in azo dyes and which is substituted by one or more fluorinated carboxylic or sulphonic ester groups. Additionally, X may be substituted by any of the groups commonly used in diazonium components such as nitro, cyano, halogen and the like. C' represents an aniline, tetrahydroquinoline or benzomorpholine coupler of the type commonly used in azo dyes. The dyes can be used in both the dyeing and heat transfer printing of textiles, are surprisingly bathochromic in shade, exhibit a good balance of properties such as light, crock, wash, and gas fastness, leveling, pH stability, and dyeability, and have unexpected thermal and hydrolytic stability as compared for example, to the hydrogen analogues. The dyes have particular utility on polyester fibers especially as regards lightfastness.
摘要:
Disclosed are disperse dyes comprising a chloro- or bromodinitroaniline azo moiety and a particular group of 2(2'-alkoxy-5'-alkanoylaminoanilino)alkane couplers. These dyes give exceptional color depth and brightness, shade permanency on heat setting, build, leveling, barre coverage, dye exhaustion and dyeing rate on fibers of polyester, cellulose acetate, cellulose triacetate, and polyamide (nylon) over widely varying dyeing conditions of, for example, temperature and pressure. The dyes exhibit blue shades with excellent colorfastness properties on polyester fibers and have excellent dyeability by heat fixation (Thermosol) or exhaust (boil and pressure) methods of application on this substrate. Uniform dyeability under a wide variety of conditions is an exceptional feature of the present dyes.
