Abstract: The novel pyridone dyes are of formula (I) (where n = 0, 1 or 2; B is a gp. of formula X-NH-Z or COO-(A-O)m X1;R1 is 1-3C alkyl; Y is Cl or Br; X is CO or SO2; X1 is C6H5, C6H5 CH2, C6H5-CH2-CH2, C6H5-O-CH2-CH2, ClC6H4 CH3-C6H4, Cl2C6H3, (CH3)2C6H3, Cl-C6H4-O-CH2-CHi or Cl2C6H3-O-CH2-CH2; Z is aralkyl interrupted by one or more O atoms; A is CH2-CH2 or CH(CH3)CH2; m = 1 or 2; R is H, 1-8C alkyl, 2-8C alkyl substd. by OH or by 1-4C alkoxy, or cyclohexyl methylcyclohexyl, norbornyl, phenylethyl, phenoxyethyl or phenoxypropyl; R is H when B is CO-NH-Z). As greenish-yellow dyes for polyesters and also for acrylonitrile polymers and cellulose esters, having excellent fastness to light moisture and heat-fixing. Intensity of colour, uniformity and other tinctorial props. are also very good.

Abstract: New tris-azo acid dyes are of formula (I): In the formula, R is H, 1-4C alkyl, mesityl, methyl phenyl or trimethyl phenyl; n is 0 or 1; X and Y are H, 1-2C alkyl or alkoxy, Cl or br; X' and Z are H, methyl, methoxy or Cl; Y and Z together may form a condensed benzene ring substd. with SO3H; and total number of SO3H gps. is 4 or pref. 3. Used for dyeing and printing of N-contg. fibres e.g. wool, silk and esp. synthetic polyamides, in navy blue shades. (I) give strong shades with good fastness to light and excellent fastness to water, washing, perspiration, sea water, etc.
