Abstract

1385003 Process for dyeing linear polyesters in the melt CIBA-GEIGY AG 6 July 1973 [7 July 1972] 32425/73 Heading C4P [Also in Division C3] A process for colouring linear polyesters in the melt is characterized by the use of an acridone of formula wherein R 1 , R 2 and R 4 denote H or halogen, C 1-6 alkyl or alkoxy groups, phenoxy groups which are optionally substituted by halogen or alkyl or -CF 3 groups, and R 3 denotes H or halogen, C 1-6 alkyl, or a phenoxy group, with at most one of these radicals denoting a halogen atom. Red to violet shades are produced with the polyesters, and polyethylene terephthalate is a particularly suitable polyester.
