## Abstract Dyeing of synthetic fibers by the heat transfer process of disperse dye vapors is performed by contacting white receptor polyester or polyamide fabric with other dyed polyester fabrics (donor) under the influence of heat. The dye vapours flowing away will diffuse across the very slight
Some novel uracil derived azo compounds were synthesized by diazotization of substituted aromatic amines, amidine-and guanidine-like amines such as 2-aminopyridine and 2-aminopyrimidine, orthohydroxy aniline and ortho-hydroxy naphthyl amines and coupling reaction with 6-amino-1,3-dimethyluracil. Str
