  "abstract": "Dyestuffs of the formula ##STR1## wherein R represents C 1 -C 5 -alkyl which is optionally substituted by fluorine, chlorine, hydroxyl or methoxy, are outstandingly suitable for printing polymeric materials in accordance with the transfer printing principle in that they produce intensely colored prints on these materials, especially on polyester and polyamide fibre materials.",
  "claims": [
    "1. Process for printing materials, preferably synthetic or partially synthetic polymeric materials, in accordance with the transfer printing principle, characterised in that dyestuffs of the formula ##STR5## wherein R represents a straight-chain or branched alkyl radical which has 1 to 5 carbon atoms and can optionally be substituted by 1 to 3 fluorine or chlorine atoms or hydroxyl or methoxy groups, are used.",
    "2. Process according to claim 1, characterised in that dyestuffs of the formula indicated in which R represents a straight-chain or branched alkyl radical which has 1 to 3 carbon atoms and can optionally be substituted by 1 to 3 flourine or chlorine atoms or by one hydroxyl or methoxy group, are used.",
    "3. Process according to claim 1, characterised in that dyestuffs of the formula indicated in which R represents a straight-chain or branched alkyl radical which has 1 to 3 carbon atoms and can optionally be substituted by 1 to 3 fluorine atoms, are used.",
    "4. Process according to claim 1, characterised in that dyestuffs of the formula indicated in which R represents methyl, ethyl, propyl or isopropyl, are used.",
    "5. Process according to claim 1, characterised in that the dyestuff of the formula indicated in which R represents ethyl, is used.",
    "6. Process according to claim 1, characterised in that the dyestuff of the formula indicated in which R represents methyl, is used.",
    "7. Printing inks and printing pastes for transfer printing, characterised in that these contain dyestuffs of claim 1.",
    "8. Temporary supports for transfer printing, characterised in that these are printed or impregnated with dyestuffs of claim 1.",
    "9. Synthetic or partially synthetic polymeric materials, characterised in that these have been dyed or printed with dyestuffs of claim 1 in accordance with the transfer printing principle.",
    "10. Polyester fibre materials, characterised in that these have been dyed or printed with dyestuffs of claim 1 in accordance with the transfer printing principle."
