[Class 70] [Also in Group IV] Filaments, films, and other shaped articles are produced from a solution or plastic mass with which is incorporated before the shaping operation a product obtained by treating with an acylating agent a dyestuff which is free from hydroxyl groups but contains at least one NH-group and which yields with strong acids no salts stable to water. At any stage before, during or after the working-up of the parent mass, the dyestuff is regenerated by a saponifi. cation process. The dye may be of the azo, azine, oxazine, thiazine, arylmethane, phthalein, or anthraquinone series, and it may contain chromium or copper in complex union. The acylating agent may be a carboxy acid halide or anhydride or a sulphonic acid halide oranhydride. It may contain a substituent which enhances the solubility of the dyestuff. Halides or anhydrides of carboxylic acids containing sulpho-, alkylamino-, or additional carboxyl groups may be used. These groups may be converted into alkali metal compounds or into quaternary ammonium compounds. Halides of sulphobenzoic, sulphonaphthoic, and sulpho-acetic acids, dialkyl amino benzoyl halides, and 4-halogenalkyl-1-benzoyl halides, may be used as acylating agents. The parent masses may have a basis of casein, or natural or artificial resin. Masses having a natural resin basis may contain copal, amber, shellac, colophony, rubber, balata, guttapercha, or wax such as carnauba or ozokerite. Masses having an artificial resin basis may contain condensation products of aldehydes with phenols, aromatic amines, urea, thio-urea, or aryl sulphamides, condensation products of polybasic acids and polyhydric alcohols, or polymerization products such as vinyl, styrene, and acrylic acid polymers. The acylated dye may be incorporated by rolling or kneading with the solid parent mass or by mixing with a solution of the mass. Fillers and plasticizers may be included. The dye compound may be saponified by treatment with ammonia, caustic soda, sodium carbonate, sodium acetate, or trisodium phosphate. Specification 505,504 is referred to.
