摘要:
A golf ball of a first color is dyed to a second color with an anionic or nonionic disperse dye. Either or both of a pigmented coating layer or an optional clear coating layer on the pigmented coating layer comprises a member selected from the group consisting of polyurethanes, polyureas, polyamides, and combinations thereof, which can be dyed by the anionic or nonionic disperse dye.

摘要:
Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredientsa) anionic and/or amphoteric surfactants,b) dyes, andc) optionally further compounds selected from the group consisting of the nonionic surfactants, the terpene hydrocarbons/alcohols, sorbitol esters and their alkoxylates, fatty acid ethanolamides, alkylpolyglycosides and solvents.The treatment is carried out at pH 4.0 to 7.5 at 80-110.degree. C. and at a liquor ratio of 5:1 to 100:1.
摘要:
A process for the preparation of compounds of the formula ##STR1## wherein the substituents X, Y and Z have the meaning given in the description, by reaction of compounds of the formula ##STR2## with a cyanide and an oxidizing agent other than Br.sub.2 in the presence of halides which offers industrial hygiene advantages and renders possible large-scale industrial access to dyestuff syntheses has been found.
摘要:
Fiber-reactive disazo dyes correspond to formula I, ##STR1## and they are present as free acids or in salt form. They are used as reactive dyes for dyeing or printing hydroxy-group-containing or nitrogen-containing organic substrates, especially leather or fibrous material, which consists of or contains natural or synthetic polyamides or natural or regenerated cellulose. The dyeings obtained have high fixation values and good light fastness.
