Abstract
Viscose, cellulose ethers and esters, polyamides and polyurethanes are mass-dyed, and solutions and products of acetyl-cellulose and nitro-cellulose, condensation resins such as aminoplasts and phenoplasts and polymerization resins such as polyvinyl chloride, polyethylene, polypropylene and polystyrene and silicone resins are coloured by dyestuffs of the formula:- <FORM:0902395/IV(a)/1> where R1 and R2 are each hydrogen or halogen, R3 is hydrogen or alkyl of up to 4 carbon atoms and B is a benzene residue free from groups imparting solubility in water. In Examples (5) polyvinyl chloride, dioctyl phthalate, a pigment of the above formula and, optionally, titanium dioxide are mixed and rolled to a red foil; and (6) an alkyd-melamine stoving lacquer, titanium dioxide and a pigment of the above formula are ground to give a red lacquer.ALSO:The invention comprises dyestuffs of the formula:-<FORM:0902395/IV (b)/1> where R1 and R2 are each hydrogen or halogen, R3 is hydrogen or alkyl of at most four carbon atoms and B is a benzene residue free from groups imparting solubility in water. The dyes are made by condensing at an elevated temperature two mols of a halide of an acid of the formula:- <FORM:0902395/IV (b)/2> with one mol of a diaminobenzene free from groups imparting solubility in water. Substituents specified for the benzene residue B are halogen, alkyl, alkoxy and nitro groups. Examples are given. The dyestuffs may be subsequently sulphonated. The dyes vat-dye cellulose, animal and synthetic fibres such as wool, silk and polyamides and polyesters, are used for pigment printing, mass-dyeing and for colouring lacquers and other products (see Groups IV(a) and VIII). Blue, red and brown shades are obtained.
