Description
1074t;~
The invention relates to the transfer printing on textile material with use of an organic-aqueous printing ink, to the organic-aqueous printing mk as such, as well as to the textile materials printed in the transfer print-ng process.
Printing inks having a purely organic or purely aqueous base as well as their use for the printing of carrier materials, particularly paper, and their use in the transfer printing process are known.
It has n~w been found that, surprisingly, also aqueous preparations can be used for the production of organic-aqueous printing inks, especially 10 for gravure printing and flexographic printing, without disadvantageous effects, such as reagglomerations, occurring.
The invention thus relates to a dry heat transfer process for trans-fer printing on textile material with the use of a printing ink having an organ-ic-aqueous base, which printing ink contains at least one binding agent, at least one organic solvent, optionally additional water, and an aqueous prepar-ation of transferable dyestuffs or optical brighteners that are insoluble to difficultly soluble in water and have a particle size of less than 10 ~, especi-~ ally less than 2 ~, which preparation has a low content of dispersing agent and ¦ a high concentration of dyestuff or of optical brightener, the binding agent 20 being capable of stabilizing the dyestuff dispersion, and having little or noaffinity to dyestuffs, optical brighteners and solvents used, and remaining ~: completely on the carrier material after the thermal transfer process, with the aqueous preparation containing at least 10 per cent by weight, particular-S ly 20 to 30 per cent by weight, of water, at least 30 per cent by weight, '~r especially 35 to 65 per cent by weight, preferably 40 to 60 per cent by weight, of a finely dispersed transferable dyestuff or optical brightener insoluble to difficultly soluble in water, and a mixture consisting of at most 10 per cent by weight, particularly 1 to 5 per cent by weight, of an anion-active dispersing :~

agent, at most 5 per cent by weight, espec:ially 1 to 3 per cent by weight, of t a nonionic dispersing agent, and at most 35 per cent by weight, particularly 5 to 20 per cent by weight, of a hydrotropic agent.
t As transferable dyestuffs insoluble to difficultly soluble in water, such dyestuffs are used which, within the scope of this definition, are suit-able for the transfer printing process, particularly disperse dyestuffs which are converted at atmospheric pressure at a temperature of between 150 and 220C,to the extent of at least 60%, in less than 60 seconds into the vapour phase, which are stable ~' ;~

Furthermore, it is possible to use in the aqueous dyestuff preparations also mixtures of identical or different types of dyestuffs within the limits as defined, as well as transferable optical brighteners.

Nonionic dispersing agents which have proved particularly favourable are condensation products of aromatic sulphonic acids with formaldehyde, such as condensation products from formaldehyde and naphthalenesulphonic acids, or from formaldehyde, naphthalenesulphonic acid and benzenesulphonic acid, or a condensation product from crude cresol, formaldehyde and naphthalenesulphonic acid, and lignin sulphonates and polyphosphates.
Fatty alcohol polyglycol ethers have proved particularly advantageous, especially those having more than 20 moles of ethylene oxide, such as cetyl-stearyl alcohol etherified with 25 moles of ethylene oxide, stearyl-oleyl alcohol etherified with 80 moles of ethylene oxide and oleyl alcohol etherified with 20 moles of ethylene oxide. Furthermore, phenol ethers such as p-nonylphenol etherified with 9 moles of ethylene oxide, ricinoleic acid ester having 15 moles of ethylene oxide and hydroabietyl ` alcohol etherified with 25 moles of ethylene oxide are also very suitable.

possible and in some cases they have synergetic effects.
By hydrotropic agents used in the aqueous dyestuff preparations of the invention are meant those agents capable of converting the transferable dyestuffs or optical brighteners insoluble to difficultly soluble in water into an appreciably better soluble form, without in the process a chemical reaction occurring between the dyestuff or optical brightener and the hydrotropic substance. These compounds should be water-soluble. Suitable substances having these properties are, e.g., hydrotropic salts such as the sodiurn salt of benzoic acid, the sodium ) .
salt of benzenesulphonic acid, the sodium salt of p-toluenesulphonic acid or the sodium salt of N-benzyl-sulphanilic acid. Compounds which have proved particularly ~ 15 advantageous in this connection are, however, nitrogen-Ç containing compounds, such as urea and derivatives thereof, ` for example dimethylurea or amides such as acetamide and propionamide.
By virtue of this combination of anion-active and nonionic dispersing agent with the hydrotropic agent, it is possible to obtain preparations which have on the one hand a low content of dispersing agent and on the , other hand a high content of dyestuff, and which are - 13 ~

by free flowability; by their finely dispersed form;
and, in particular, by their low viscosity in the range of about 1 to 1000 cP/20C.
If desired or req~lired, there can be added to these preparations further additives to improve properties, such as hygroscopic agents, e.g. glycols or sorbitols; antifrost agents, e.g. ethylene glycol or monopropylene glycol;
antimicrobicsj fungicides, e.g. aqueous formalin solution;
antifoaming agents and agents improving viscosity, such as carboxymethylcellulose or silicic acid aerosil 300, which increase the viscosity of the printing ink and prevent sedimentation of the dyestuff or optical brightener.
By virtue of their high content of dyestuff and low content of dispersing agent and extenders, these preparations ~` can be processed into low-viscous (about 20 to 700 cP/20C, corresponding to approx. 15 to 200 seconds in the Ford viscosimeter-cup 4) organic-aqueous printing inks having an adequat~ concentration of dyestuff or optical brightener.

~074956 These oL-g-lnic-aqueous prin~ing inks are produced by methods kno~n per se, e.g. by diluting the aqueous preparations as defined in the organic solvent or solvent mixture, in the presence of a binding agent, op~ionally with a further addition of water, and stirring with intense turbulence.
Suitable organic solvents are, in par~icular: the first members of the straight-chain and branched chain aliphatic monovalent and bivalent alcohols, such as methanol, ethanol, n- and iso-propanol and ethylene glycol, or ~ mixtures of such alcohols, such as a mixture of methanol j and isopropanol, also mixtures of such alcohols with ~- benzine having boiling limits between 110 and 180C, t in the ratio of ~3:1, with aliphatic ketones, such as a mixture of ethanol/methyl ethyl ketone and ethanol/
methyl isobutyl ketone, or with nitroparaffins such as isopropanol/nitromethane. The range is advantageously .
limited to these solvents and mixtures thereof, because ;~rr on the one hand they do not dissolve to intensively the transferable dyestuffs and optical brighteners concerned, . and on the other hand they evaporate sufficiently rapidly.
Furthermore, they must be able to be combined with a specific proportion of water without any gap in the range ~ .

Effective binding agents used in these organic-aqueous printing inks should stabilise the dyestuff dispersion, should have little or no affinity to the dyestuffs, optical ~- brighteners and solvents used, should merely retain these on the printed area of the inert carrier without modifying them, and should remain completely on the carrier material after the thermal transfer process. Preferred binding agents are those which are soluble in the mixture of water and organic solvent or in the mixture of organic solvents, and which rapidly $ and completely dry in, for example, a warm stream of air ~ and form a fine film on the carrier material, and which y are able to bind the dyestuff well, i.e. to render it fast to rubbing. Furthermore, it is important that the binding agents - or at least one of the constituents in the case of combinations - impart to the printing ink `' the specific viscosity that is required for the printing ~` process. In this connection, binding agents that have ;

Thus, a further aspect of the invention provides a printing ink for ~` a dry heat transfer process and having an organic-aqueous base, which printing i ink contains at least one binding agent, at least one organic solvent, option-ally additional water, and an aqueous preparation of transferable dyestuffs or optical brighteners that are insoluble to difficultly soluble in water and have a particle size of less than 10 ~, especially less than 2 ~, which prepar-ation has a low content of dispersing agent and a high concentration of dye-i stuff or of optical brightener, the binding agent being capable of stabilizing ', the dyestuff dispersion, and having little or no affinity to dyestuffs, optical brighteners and solvents used, and remaining completely on the carrier material after the thermal transfer process, with the aqueous preparation containing at least 10 per cent by weight of water, at least 30 per cent by weight of a finely dispersed transferable dyestuff or optical brightener insoluble to dif-~ ficultly soluble in water, and a mixture consisting of at most 10 per cent by ', weight of an anion-active dispersing agent, at most 5 per cent by weight of a nonionic dispersing agent, and at most 35 per cent by weight of a hydrotropic , agent.

i : ' The carrier ma~erlals that are printed with such organic-aqueous printing inlcs are krlown, and consist advantageously of a flexible sheet material that is preferably dimen-sionally stable, such as a strip, band or sheet, preferably having a smooth surface. These carrier materials must be stable to heat, and they are made of the most varied types of materials, particularly non-textlle materials, such as metal, e.g. an aluminium or steel sheet; or they consist cf a continuous strip of stainless steel, plastics, paper ~ B lo or Cellophane, preferably of a clean, non-lacquered cellulose parchment paper, which is optionally coated with a film of vinyl resin, ethylcellulose, polyurethane resin or Teflon.
The optionally filtered organic-aqueous printing inks are applied to the carrier material, in places or over the : .
lS whole surface, by, for example, spraying, coating or, :j, f~ advantageously, printing. There can also be applied to the carrier material a multicoloured pattern, or the ~ .
s carrier material can be printed with a ground shade and thereafter successively with identical or different designs.
, 20 After application of the printing ink to the carrier . material, this is dried, e.g. with the aid of a warm flow -~ of air or by infra-red irradiation.
;; . .
~ The carrier materials can be printed also on both , ra~na~k i ., ' ~ .
.,s' ,.
s :; : . ~ ;
sides, and it is possiblc to select different colours and/or designs for the two sides. In order to avoid the use of a printing machine, the printing inks can be sprayed onto the carrier materials by means of, for example, a spray gun. Particularly interesting effects are obtained when simultaneously more than one shade is printed or sprayed on the carrier material. Specific designs can be obtained, e.g., by the use of stencils, or artistic designs can be applied by brush. If the carrier material is printed, then the most diverse printing processes .
may be employed, such as high-pressure processes (e.g.
letter-press printing, flexographic printing), gravure printing (e.g. roller printing), screen printing (e.g.
rotary printing or film printing) or electrostatic printing processes.
The transfer from the carrier material to the organic ~- material to be printed is effected in the usual manner by the action of heat. For this purpose, the treated carrier ~aterials are brought into contact with the materials % 20 to be printed, especially textile materials, and are ; held at about 120 to 210C until the dyestuffs or optical ~ brighteners applied to the carrier material have been $............. transferred to the textile material. As a rule, 5 to 60 seconds are sufficient to achieve this.

~:~ After completion of the heat treatment, the printed organic material is separated from the carrier material.
This organic material requires no aftertreatment, neither a steam treatment to fix the dyestuff or optical brightener, nor a washing treatment to improve the fastness properties~
All synthetic fibres, provided that their thermal stability is adequate for the process, are in general suitable for printing in the transfer printing process.
Suitable fibres in practice are polyester, polyacrylonitrile and polyamide fibres, cellulose-2 1/2-fibres and cellulose triacetate fibres, as well as mixtures of these with each other, or admixtures of cellulose fibres or albumin fibres.

The invention relates to the transfer printing on textile material with use of an organic-aqueous printing ink, to the organic-aqueous printing mk as such, as well as to the textile materials printed in the transfer print-ng process.
Printing inks having a purely organic or purely aqueous base as well as their use for the printing of carrier materials, particularly paper, and their use in the transfer printing process are known.
It has n~w been found that, surprisingly, also aqueous preparations can be used for the production of organic-aqueous printing inks, especially 10 for gravure printing and flexographic printing, without disadvantageous effects, such as reagglomerations, occurring.
The invention thus relates to a dry heat transfer process for trans-fer printing on textile material with the use of a printing ink having an organ-ic-aqueous base, which printing ink contains at least one binding agent, at least one organic solvent, optionally additional water, and an aqueous prepar-ation of transferable dyestuffs or optical brighteners that are insoluble to difficultly soluble in water and have a particle size of less than 10 ~, especi-~ ally less than 2 ~, which preparation has a low content of dispersing agent and ¦ a high concentration of dyestuff or of optical brightener, the binding agent 20 being capable of stabilizing the dyestuff dispersion, and having little or noaffinity to dyestuffs, optical brighteners and solvents used, and remaining ~: completely on the carrier material after the thermal transfer process, with the aqueous preparation containing at least 10 per cent by weight, particular-S ly 20 to 30 per cent by weight, of water, at least 30 per cent by weight, '~r especially 35 to 65 per cent by weight, preferably 40 to 60 per cent by weight, of a finely dispersed transferable dyestuff or optical brightener insoluble to difficultly soluble in water, and a mixture consisting of at most 10 per cent by weight, particularly 1 to 5 per cent by weight, of an anion-active dispersing :~

agent, at most 5 per cent by weight, espec:ially 1 to 3 per cent by weight, of t a nonionic dispersing agent, and at most 35 per cent by weight, particularly 5 to 20 per cent by weight, of a hydrotropic agent.
t As transferable dyestuffs insoluble to difficultly soluble in water, such dyestuffs are used which, within the scope of this definition, are suit-able for the transfer printing process, particularly disperse dyestuffs which are converted at atmospheric pressure at a temperature of between 150 and 220C,to the extent of at least 60%, in less than 60 seconds into the vapour phase, which are stable ~' ;~

By hydrotropic agents used in the aqueous dyestuff preparations of the invention are meant those agents capable of converting the transferable dyestuffs or optical brighteners insoluble to difficultly soluble in water into an appreciably better soluble form, without in the process a chemical reaction occurring between the dyestuff or optical brightener and the hydrotropic substance. These compounds should be water-soluble. Suitable substances having these properties are, e.g., hydrotropic salts such as the sodiurn salt of benzoic acid, the sodium ) .
salt of benzenesulphonic acid, the sodium salt of p-toluenesulphonic acid or the sodium salt of N-benzyl-sulphanilic acid. Compounds which have proved particularly ~ 15 advantageous in this connection are, however, nitrogen-Ç containing compounds, such as urea and derivatives thereof, ` for example dimethylurea or amides such as acetamide and propionamide.
By virtue of this combination of anion-active and nonionic dispersing agent with the hydrotropic agent, it is possible to obtain preparations which have on the one hand a low content of dispersing agent and on the , other hand a high content of dyestuff, and which are - 13 ~

by free flowability; by their finely dispersed form;
and, in particular, by their low viscosity in the range of about 1 to 1000 cP/20C.
If desired or req~lired, there can be added to these preparations further additives to improve properties, such as hygroscopic agents, e.g. glycols or sorbitols; antifrost agents, e.g. ethylene glycol or monopropylene glycol;
antimicrobicsj fungicides, e.g. aqueous formalin solution;
antifoaming agents and agents improving viscosity, such as carboxymethylcellulose or silicic acid aerosil 300, which increase the viscosity of the printing ink and prevent sedimentation of the dyestuff or optical brightener.
By virtue of their high content of dyestuff and low content of dispersing agent and extenders, these preparations ~` can be processed into low-viscous (about 20 to 700 cP/20C, corresponding to approx. 15 to 200 seconds in the Ford viscosimeter-cup 4) organic-aqueous printing inks having an adequat~ concentration of dyestuff or optical brightener.

limited to these solvents and mixtures thereof, because ;~rr on the one hand they do not dissolve to intensively the transferable dyestuffs and optical brighteners concerned, . and on the other hand they evaporate sufficiently rapidly.

Effective binding agents used in these organic-aqueous printing inks should stabilise the dyestuff dispersion, should have little or no affinity to the dyestuffs, optical ~- brighteners and solvents used, should merely retain these on the printed area of the inert carrier without modifying them, and should remain completely on the carrier material after the thermal transfer process. Preferred binding agents are those which are soluble in the mixture of water and organic solvent or in the mixture of organic solvents, and which rapidly $ and completely dry in, for example, a warm stream of air ~ and form a fine film on the carrier material, and which y are able to bind the dyestuff well, i.e. to render it fast to rubbing. Furthermore, it is important that the binding agents - or at least one of the constituents in the case of combinations - impart to the printing ink `' the specific viscosity that is required for the printing ~` process.

lS whole surface, by, for example, spraying, coating or, :j, f~ advantageously, printing. There can also be applied to the carrier material a multicoloured pattern, or the ~ .
s carrier material can be printed with a ground shade and thereafter successively with identical or different designs.
, 20 After application of the printing ink to the carrier . material, this is dried, e.g. with the aid of a warm flow -~ of air or by infra-red irradiation.
;; . .
~ The carrier materials can be printed also on both , ra~na~k i ., ' ~ .
.,s' ,.
s :; : . ~ ;
sides, and it is possiblc to select different colours and/or designs for the two sides. In order to avoid the use of a printing machine, the printing inks can be sprayed onto the carrier materials by means of, for example, a spray gun. Particularly interesting effects are obtained when simultaneously more than one shade is printed or sprayed on the carrier material. Specific designs can be obtained, e.g., by the use of stencils, or artistic designs can be applied by brush. If the carrier material is printed, then the most diverse printing processes .
may be employed, such as high-pressure processes (e.g.
letter-press printing, flexographic printing), gravure printing (e.g. roller printing), screen printing (e.g.
rotary printing or film printing) or electrostatic printing processes.
The transfer from the carrier material to the organic ~- material to be printed is effected in the usual manner by the action of heat. For this purpose, the treated carrier ~aterials are brought into contact with the materials % 20 to be printed, especially textile materials, and are ; held at about 120 to 210C until the dyestuffs or optical ~ brighteners applied to the carrier material have been $............. transferred to the textile material. As a rule, 5 to 60 seconds are sufficient to achieve this.

~074956 The actioll of heat Call be applied by various kno~n methods, for example by passage over a hot heating cylinder, by passage through a Lunnel-shaped heating zone, or by means of a heated roller, advantageously together with a pressure-exerting, heated or unheated counter roller, or by means of a hot calender, or with ., the aid of a heated plate, optionally under vacuum, , which devices are preheated to the required temperature s by steam, oil, infra-red irradiation or microwaves, or which are located in a preheated heating chamber.
~:~ After completion of the heat treatment, the printed organic material is separated from the carrier material.
This organic material requires no aftertreatment, neither a steam treatment to fix the dyestuff or optical brightener, nor a washing treatment to improve the fastness properties~
All synthetic fibres, provided that their thermal stability is adequate for the process, are in general suitable for printing in the transfer printing process.
Suitable fibres in practice are polyester, polyacrylonitrile and polyamide fibres, cellulose-2 1/2-fibres and cellulose triacetate fibres, as well as mixtures of these with each other, or admixtures of cellulose fibres or albumin fibres.
