Definitions
- a transfer sheet which contains a sublimable dye, optionally together with a binder on a support, is heated from the back with a heating head with short (duration: fractions of a second) heating pulses, the dye subliming or evaporating and on a recording medium is transferred.
- the main advantage of this method is that it is easy to control the amount of dye to be transferred (and thus the color gradation) by adjusting the energy to be delivered to the heating head.
- JP-A 159091/1985 describes dyes of the formula in which R is alkyl, aralkyl, aryl or a 5- / 6-membered carbocyclic ring means described for this purpose.
- JP-A 30392/1985 are dyes of the formula known in which R, R1 and R 2 are allyl, alkyl, alkoxyalkyl and XH, methyl.
- JP-A 239292/1985 uses dyes of the formula for the transfer described.
- R 1 is 1-8 C, alkyl
- R 2 is H or methyl
- D is Quinone derivatives of the formula in which R and R 1 denotes methyl, ethyl, propyl or butyl are described for this application in JP-A 229 786/1985.
- the invention had for its object to provide dyes which are easily sublimable or evaporable under the conditions of a thermal head, which do not undergo thermal and photochemical decomposition, which can be processed into printing inks and which meet the color requirements.
- the dyes should be easily accessible technically.
- the dyes used in the process according to the invention are distinguished by better sublimability, in some cases higher light fastness or by higher resistance to chemical substances.
- R 1 and R 2 include, for example: C 1 -C 4 -alkyl such as CH 3 , C 2 Hs, n-propyl, isopropyl, n-butyl, isobutyl, tertiary-butyl; C 1 - to C 4 alkoxy such as methoxy, ethoxy, propyloxy, isopropyloxy, n-butyloxy, isobutyloxy, tertiary-butyloxy; Ci to C 4 alkylthio such as methylthio, ethyl and butyl hio and halogen such as bromine, preferably chlorine and fluorine.
- R1 can also form a heterocyclic ring together with R, so that can correspond to the following formulas: and
- C i - to C 6 alkyl which may be mentioned in detail, for example: methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, t-butyl, n-pentyl, i-pentyl, n-hexyl, i-hexyl.
- C 1 -C 4 -alkoxy in the alkoxy-bearing substituents are: methoxy, ethoxy, n- and i-propoxy and n- and i-butoxy.
- Halogen is suitable as a substituent on C 1 -C 6 -alkyl, bromine, chlorine, preferably fluorine.
- C 2 - to Cs-alkanoyl examples include acetyl, propionyl, butanoyl and pentanoyl.
- R 'and R can also be phenyl which is optionally substituted by methyl or methoxy, C 5 -C 6 -cycloalkyl or benzyl.
- Dimethylamino, diethylamino or N-ethyl-N-exthoxyethylamino are, except when R 1 and R 2 are hydrogen.
- the dyes (I) are synthesized by known processes or processes known per se.
- Azo dyes (I) with were synthesized by the method described in DE-A 31 08 077 and 35 29 831.
- Dyes of the type were developed according to the method of Mc Kusick et al., J. Am. Chem. Soc. (1958), 80, 2806 described process by reacting the corresponding aniline derivatives with tetracyanoethylene.
- the dyes are in a suitable solvent, e.g. Chlorobenzene or isobutanol processed with a binder to form a printing ink.
- a suitable solvent e.g. Chlorobenzene or isobutanol processed with a binder to form a printing ink.
- the printing ink is applied to the inert carrier using a doctor blade and the dyeing is air-dried.
- binders come e.g. Ethyl cellulose, polysulfones or polyethersulfones into consideration.
- Inert carriers are e.g. Tissue paper, blotting paper or glassine paper as well as plastic films with good heat resistance, e.g. optionally metal-coated polyester, polyamide or polyimide.
- the thickness of the carrier is preferably 3 to 30 microns. Further suitable carrier materials, binders and solvents for the production of the printing inks are described in DE-
- the transfer takes place by means of a thermal head, which must deliver sufficient heating power so that the dye is transferred within a few milliseconds.
- the paper layer (donor) coated with the dye to be tested is placed with the dye layer on an 80 ⁇ m thick polyester film (receiver) and pressed on.
- the encoder / receiver is then wrapped with aluminum foil and heated between two heated plates for 30 seconds.
- the amount of dye migrated into the PES film is determined photometrically. If the logarithm of the absorbance A of the colored polyester films measured at different temperatures (range: 100 to 200 ° C) is plotted against the associated reciprocal absolute temperature, straight lines are obtained, from the slope of which the activation energy A E T for the transfer experiment is calculated:
- the temperature T * [ ° C] is additionally taken from the plots at which the extinction A of the colored polyester film reaches the value 1.
- the dyes specified in Tables 1 to 6 were processed according to Al) or All) and the dye-coated supports obtained according to B) were tested for the sublimation behavior.
- the table shows the color shade on polyester as well as the thermal transfer parameters T * and ⁇ ET.
