Abstract
Viscose rayon, cellulose acetate rayon, nylon, polyesters and polyvinyl chloride are spin-dyed with a dyestuff of the formula:- <FORM:0887971/IV (a)/1> where R is a p-phenylene or a 4:41-diphenylene radical. Red dyeings are obtained. In an Example (5), polyvinyl chloride, dioctyl phthalate and a dyestuff of the above formula where R is p-phenylene are mixed and rolled.ALSO:The invention comprises dyestuffs of the formula <FORM:0887971/IV (c)/1> wherein R is a p-phenylene or a 4 : 41-diphenylene radical. The dyes are made by condensing perylene-3 : 4 : 9 : 10- tetracarboxylic acid or its anhydride with a p-amino-hydroxybenzene or a 4 : 41-amino-hydroxydiphenyl at a raised temperature or by treating the diisopropyl ether of a dyestuff of the above general formula with aqueous sulphuric acid. The diisopropyl ether when R is p-phenylene is made by condensing p-isopropoxyaniline with perylene-tetracarboxylic acid anhydride. Examples are given.
