Definitions

  • the invention relates to transfer printing media which are characterized in that they are impregnated or printed with a preparation which is a mixture of a blue, slightly subliming disperse dye of the general formula I.
  • X represents a hydrogen or halogen atom
  • R, R 1 and R 2 each represent an alkyl group of 1 to 4 carbon atoms
  • R 3 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms
  • the preparations can additionally a blue, slightly subliming disperse dye of the general formula II in which Y is a hydrogen or halogen atom, R 4 represents a methoxy or ethoxy group, or, if Y is a chlorine or bromine atom, also represents a hydrogen atom or a methyl group, R s is an alkyl group having 1 to 4 carbon atoms , R 6 is a hydrogen atom or has the meaning of R 5 and R 7 represents an alkyl group having 1 to 4 carbon atoms, for example the dye of the formula or additionally a blue, slightly subliming anthraquinone dye, such as, for example, the disperse dyes CI Disperse Blue, 3, 7, 14, 19 and 26, or additionally the yellow dye of the formula contain.
  • Y is a hydrogen or halogen atom
  • R 4 represents a methoxy or ethoxy group, or, if Y is a chlorine or bromine atom, also represents a hydrogen atom or a methyl
  • the invention further relates to a process for the production of these transfer printing carriers, which is characterized in that the carrier material is impregnated or printed with the preparations mentioned above.
  • the invention further relates to the use of these supports for dyeing and printing sheet-like structures by the thermal transfer printing process.
  • Slightly subliming dyes are to be understood in all cases as substances which sublimate at least 60% without decomposition at atmospheric pressure between 150 and 220 ° C.
  • the blue dyes are always the main constituent; if blue dyes other than those of formula 1 are used, the dye of the formula is usually present in at least 10, preferably 50%, based on the weight of all blue dyes.
  • the dye combinations according to the present invention are distinguished by a number of advantages over known black mixtures.
  • easy-to-pour, low-electrolyte and low-dispersant formulations can be produced with a high dye concentration, which are particularly sought after as printing pastes for printing on paper, since only small amounts of printing paste are required.
  • the blends also show excellent transfer behavior and deliver color-deep prints with a sharp print image.
  • the high light-fastness of the black colorations obtained, which exceeds that of the blue components of the formula I, is particularly surprising.
  • Sheet structures which are inert to the dyes applied and which do not hinder sublimation are suitable as carrier material for the transfer printing supports according to the invention.
  • the formulations which contain the dye mixtures and with which the carrier materials are impregnated or printed can be aqueous printing pastes, as are customary in textile printing, or organic printing inks, as are used in graphic printing.
  • Aqueous printing inks contain the usual natural or synthetic thickeners, for example polyvinyl alcohols, methylcelluloseose or polymerization products containing carboxy groups, for example polyacrylates.
  • composition of the organic printing inks depends on the type of substrate, the substrate, the printing process and the equipment available.
  • such printing inks consist of the dye mixtures described above, a binder, one or more dispersants and, if appropriate, solvents, fillers and preservatives.
  • Suitable binders are natural, semi-synthetic and synthetic resins, i.e. H. Polymerization, polycondensation and polyaddition products.
  • suitable resins are: rosin and its derivatives, maleinate resins, oil-free alkyd resins, alkyd resins made from synthetic and natural fatty acids and arylated alkyd resins.
  • Terpene resins polyvinyl resins such as polyvinyl acetate and polyvinyl chloride, copolymers and graft polymers with various vinyl monomers, acrylate resins, naphthalene-formaldehyde resins, ketone resins, silicone resins and cellulose derivatives such as cellulose esters, for example nitrocellulose or cellulose acetate, and cellulose ethers, such as, for example, methyl cellulose polysaccharide and others, are also suitable.
  • polyvinyl resins such as polyvinyl acetate and polyvinyl chloride
  • copolymers and graft polymers with various vinyl monomers acrylate resins, naphthalene-formaldehyde resins, ketone resins, silicone resins and cellulose derivatives such as cellulose esters, for example nitrocellulose or cellulose acetate, and cellulose ethers, such as, for example, methyl cellulose polysaccharide and others, are also suitable.
  • Nonionic and anionogenic products are preferably used as dispersants.
  • nonionic products are: addition products of alkylene oxide with fatty acids, fatty alcohol polyglycol ethers, phenol and alkylphenol polyglycol ethers, but also oxalkylates of fatty acids esterified with polyhydric alcohols or of resin derivatives such as hydroabietyl alcohol.
  • Suitable anionic dispersants are: naphthalenesulfonic acid-formaldehyde condensates, ligninsulfonates and sulfite waste products.
  • esters, ketones or alcohols for example butyl acetate, acetone, methyl ethyl ketone, ethanol, isopropanol or butanol, are particularly preferred.
  • the preparations (printing inks) discussed here can either be obtained by mixing and adjusting preparations of the individual dyes.
  • the procedure can also be such that presscake of the individual dyes required for the dye mixture is combined, ground with the addition of suitable dispersants, so that at least 90% of the dispersed particles are less than 3 ⁇ m, and adjusted to the desired dye content.
  • the printing inks can be printed using all common printing methods, i.e. high, flat, gravure or screen printing.
  • Rotogravure and rotary film printing are particularly suitable printing processes for the production of printed paper auxiliary substrates.
  • Suitable substrates are sheet-like structures such as nonwovens, felts, furs, carpets, foils and, above all, woven and knitted fabrics made from synthetic or partially synthetic materials, in particular from aromatic polyesters such as polyethylene glycol terephthalate or cellulose acetates such as cellulose triace tat and cellulose-2 1/2 acetate or polyamides.
  • synthetic or semi-synthetic materials show an affinity for the dye mixtures.
  • Thermal transfer printing is generally known and is described in detail, for example, in FR-A-1 223 330, 1 334829 and 1 585119.
  • the auxiliary carriers which are impregnated or printed with the suitable preparations, are brought into close contact with the substrate to be colored or printed, whereupon the dye is transferred from the carrier to the substrate and fixed there under the action of heat and, if appropriate, pressure or vacuum .
  • JP-A-77136 275 describes a process for printing molded structures made of polyester by the thermal transfer printing process, using monoazo dyes of a certain general formula.
  • a mixture of a disperse dye which falls under the general formula I of claim 1 of the present invention comes in combination with, inter alia, the orange dye of the formula to use.
  • the orange dye of the formula used in accordance with the invention in combination with a blue disperse dye of the formula I is distinguished due to a much better lightfastness when dyeing polyester fabric, which is surprising in view of the structural similarity of the two orange dyes.
