Definitions

  • the present invention relates to new auxiliary supports for transfer printing, also known as dry printing or gas-phase thermal printing.
  • the auxiliary supports used in dry transfer printing are generally sheets or strips of paper which carry the dye (s) which are transferred hot to the material to be printed.
  • the required penetration of the dyes into the material to be dyed or printed is obtained, either by using auxiliary supports carrying so-called "penetrating" dyes. that is to say dyes which already below 180 C sublimate or vaporize more than 50% in less than 25 seconds, either by carrying out the transfer operation under reduced pressure.
  • Porous transfer supports have also been used to increase the penetration of sublimable dyes into the dyeing material, through which a current of hot air is passed during the transfer (see German patent application). 26 28 676 and French patents 21 14 925, 22 47 356 and 22 60 452). These porous or perforated substrates do not allow regular printing of large areas, probably because of the inconsistent texture of the porous papers used.
  • German patent application 27 40 137 the surface perforation of the printed face of auxiliary supports is described during their passage through a vacuum transfer calender to allow better elimination of the moisture present in these supports. This kind of incomplete perforation and of variable dimensions does not make it possible to obtain auxiliary supports usable in the transfer process in which a current of hot air entrains the product or products to be transferred.
  • the papers claimed and described in German application 28 15 864 from the company known as Armstrong Cork Corporation can be used in this technique, their only drawback being that on very thick materials the intensity of the print leaves something to be desired: when the penetration is sufficient, the intensity is too low and when the quantity of air is reduced to have sufficient intensity, it is the penetration which no longer is.
  • the supports of the present invention overcome the drawbacks of known auxiliary supports and also have the advantage of extending the range of supports available and the scope of the transfer technique. In fact, the supports of the present invention allow the transfer operation to be carried out on materials on which only satisfactory results were obtained with the known supports.
  • polyester refers to films or sheets or fibers of poly (ethylene terephthalate).
  • porous paper is meant both papers in the literal sense of the term as thin felts or nonwovens of cellulosic fibers, or perforated papers. It is also possible, by any desired method, to print sheets or strips of cellophane, of aluminum or of little or not porous paper (which are easier to print than porous papers).
  • the printing is done before or after perforation with aqueous or solvent printing inks which contain a binder (see French patents 1 223 330 and 1 575 069 for example) and one or more coloring matters free from strongly acid groups such as sulfonic groups.
  • the binder serves both to disperse dye in the ink and to thicken the ink; it will also retain the dye on the printed side of the support.
  • binders are well known to those skilled in the art, as are printing methods.
  • To prepare the supports of the present invention which must bear colored areas of at least 0.2 and preferably at least 0.4 g of dye per m it is necessary, it goes without saying, to ensure that the ink contains enough dye; in general, inks containing 0.2 to 20% dye are used and enough ink is printed to have the desired amount of ink per m 2 . It is advantageous to use an ink quantity that is larger the thicker the material to be thermo-printed with the support. Thus, for materials more than 1 mm thick, supports are used, depending on the desired penetration, the patterns to be transferred can contain up to 1.6 and even 2 g of ink per m 2 .
  • the porous papers of the present invention are printed like the papers little or not porous, but it is then advantageous to use more concentrated inks or else to coat in surface the porous papers with a smooth layer which facilitates their printing.
  • the papers of the present invention must be heat stable and they must have sufficient tensile and tear strength so that they can be printed and used in a machine for continuous transfer in which air at a temperature of up to 260 0 is pressed through the printed paper and the material to be dyed (printed).
  • strips of paper at least 1 m wide and several tens or even several hundred meters long are used, for example, the papers indicated in German patent application 28 15 864, which are printed as indicated above.
  • the substrates with little or no porosity must be perforated so that, under a pressure of 98.1 Pa (that is to say under a pressure of 1 g per cm2), they allow between 50 and 500, preferably 100 to 300 liters of air per second per square meter.
  • the perforation can be done in a manner known per se, for example, by means of a laser, by electrical discharge or mechanically.
  • the protruding points can have any desired section: oval, round, square, rectangular or even triangular or houndstooth. They are preferably cylindrical and ensure a regular perforation right through, c t is to say that each has substantially the same section perforation along its entire length and that the perforations are distributed over the colored surface of the support according to the invention so that in each surface unit there are the same number of perforations of the same section, These are preferably of a diameter less than 80 micrometers and spaced from each other by 100 to 200 micrometers, the total area of the perforations not exceeding 10% of the total area of the colored area.
  • the printed supports of the present invention make it possible to dye and deeply print thick materials (carpet, velvet, etc.) without having to use so-called "penetrating” dyes, that is to say ie using less volatile dyes than those used in the conventional thermo-printing process (35 seconds at 210 ° ); these coloring matters pass into the vapor state below 310 ° but cannot be used in this process due to their too low volatility.
  • These coloring matters are generally of the type of so-called dispersion dyes, vat dyes or pigments.
  • They may be indigoldes, especially thioindigoldes, azo dyes with a molecular weight between 340 and 600, preferably those which derive from arylides of B-hydroxynaphthoic or acetylacetic or even benzoylacetic acid and which have a weight molecular at least 400, anthraquinonics also with a molecular weight between 340 and 600 or even disazo dyes, styrylic derivatives, etc.
  • the conventional dyes used in dry transfer are visible, in this test, on 3 to 9 fabrics stacked one on the other, while the dyes to be used according to the present invention are only on the fabric closest to the transfer paper or the two closest.
  • Dyes which transfer without significant decomposition below 310 ° and which reach their maximum intensity at transfer under atmospheric pressure, above 225 ° (maximum of the transfer curve) fulfill the most important condition for use in the present invention.
  • dyes of this kind By way of example of dyes of this kind, one can mention: 1- (p-toluene-sulfonylamino) -4-hydroxyanthraquinone, l- (p-phenylbenzoylamino) -anthraquinone, 1-amino-2-methoxy-4 -benzoylamino-anthraquinone, its methyl- or methoxy-benzoyl- derivatives, 1,4 and 1,5-diphenylamino-anthraquinones and their derivatives carrying one or more methyl groups the, one or more chlorine, fluorine or bromine atoms, or even one or more trifluormethyl groups, indanthrene, benzoylamino-isothiazolanthrone 1-amino-4-hydroxy-2- (B-phenoxycarbonyloxy-ethyloxy) -anthraquinone, the B-methoxy-propyl-or-ethylimide of 1,
  • supports according to the present invention are obtained which are particularly advantageous when aqueous or solvent inks are used for printing the porous (or perforating) papers indicated above, which also contain at least 10%, preferably 25 to 75%, of a more volatile dye which transfers in the vapor phase at 200 ° under atmospheric pressure and which reaches the maximum of its transfer curve between 205 0 and 220 0 in 35 seconds of transfer at this temperature.
  • more volatile dyes for example those which in 35 seconds of transfer at atmospheric pressure reach the maximum of their transfer curve already below 205 should be avoided, because they give supports of little interest, the dyes of this type passing through all the material to be dyed or printed and sometimes even causing pollution of the equipment used.
  • the dyes to be used to prepare the auxiliary supports of the present invention are for the most part known. They are found commercially among the dyes in the Dybln ranges from Du Pont, Cellestren by BASF, Terasil-X by Ciba-Geigy and in the corresponding ranges by other manufacturers of dyes (Sandoz, ICI, Bayer, etc.).
  • auxiliary supports are obtained which can carry a single layer of dye or patterns of several colors. In the latter case, much better results are obtained when not left empty (ie not printed) the white parts of the drawing, but that one prints them using a colorless ink of the type of the colored inks used to print the drawing itself.
  • the paper thus obtained can be used to print by transfer a red pattern on a polyester velvet for example on a velvet with a pile height of 2mm such as that of the house Viscosuisse (type 110 f 23 x 1HE) which weighs 260 g / m 2 .
  • a red pattern on a polyester velvet for example on a velvet with a pile height of 2mm such as that of the house Viscosuisse (type 110 f 23 x 1HE) which weighs 260 g / m 2 .
  • the pressure drop of 1.1 g / m 2 on the surface of the pile In the sandwich formed by the paper and the pile the pressure drop of 1.1 g / m 2 on the surface of the pile.
  • the air temperature is 235 ° and that on the surface of the material to be im primer is 215 °, thus obtaining a solid red impression in the light and good penetration.
  • An air flow (X) is sucked through a filter paper of given section and under a constant vacuum (2.5 mm H 2 0). An amount of air is therefore measured, unlike the pressure drop where a vacuum is determined according to a given flow rate.
  • the air volume (X) is reduced to a unit of time for a given surface (929 cm 2 ) and is expressed in CFM (cubic feet minute).
  • the porosity of Binzer VL 200 paper measured in this way is 76 CFM, that is to say 2.15 m 3 / min.
  • Binzer paper papers with a permeability less than half but more resistant to traction and better calendered are used in the same way. Auxiliary supports are also obtained which are very suitable for thermal printing in an air stream.
  • Example 1 The operation indicated in Example 1 is repeated, but using only the dye 1-amino-2-ethoxy-4-hydroxyanthraquinone which carries in position B of the ethoxy residue the substituent of formula -0-CO- 0-C 6 H 5 .
  • the velvet is printed under the conditions indicated. A lighter shade is obtained than in Example 1, but more solid in light.
  • a pattern is printed on the rotary frame on a paper having a porosity of 26 CFM, i.e. 130 l / sec.m 2 (type 2018 from the house of ARJOMARI) using a red ink containing the dye 1-amino-2-methoxy-4-benzoylamino-anthraquinone, the white parts of the motif being printed with a "white” ink containing a mixture of thickeners and, instead of coloring, an optical whitening agent of the kind of those indi ques to French patent 157 4528.
  • thermo-printing support After drying, an auxiliary thermo-printing support is obtained, making it possible to print polyester velvet or polyester-cotton in a stream of hot air, for example as follows: the printed side of the support is applied to the velvet. A stream of air heated to 240 ° is passed for 30 seconds through the paper and the pile, at a rate of about 35 m 3 / h under a pressure of 0.9 g / m 2 from the paper to the pile. reaches a surface temperature of around 216 °. This gives a solid impression and very good penetration.
