Definitions

• ABSTRACT Transfer materials which comprise a substrate which has been printed or otherwise coloured with one or more inks each of which contains two or more sublimable disperse dyestuffs which give a similar shade but which are of differing degrees of volatility, and the use 'of the said transfer materials for colouring synthetic textile materials.
• a transfer material comprising a substrate such as paper which carries a printed pattern which has been produced from inks containing sublimable dyestuffs is placed in contact with a synthetic textile material which are then heated together in contact, Under these conditions the dyestuff is transferred by volatilisation or sublimation from the transfer material to the textile material which is thus coloured in a pattern which is a mirror image of that appearing on the transfer material.
• this process is suitable for use with thin textile materials, the use of thick textile materials, for example carpets or rugs, can give rise to serious difficulties in that only the surface is coloured (i.e. the tips of the tufts or pile), the majority of the goods remaining uncoloured so that they exhibit the well known defect of grinning.
• transfer materials which comprise a substrate which has been printed or otherwise coloured with one or more inks each of which contains two or more sublimable disperse dyestuffs which give a similar shade but which are of differing degrees of volatility.
• the transfer materials of the invention can be produced in conventional manner by printing a substrate with one or more inks each of which contains two or more sublimable disperse dyestuffs which give a similar shade but are of differing degrees of volatility, by conventional printing processes, for example by gravure, lithographic, flexographic or screen printing processes on printing machinery which is commonly employed for this purpose, drying being carried out after the application of each ink.
• the inks used to print the said transfer materials are of the types which are conventionally employed for this purpose, the only difference residing in the use of the two dyestuffs having properties as previously stated.
• mixtures of dyestuffs for example a mixture ofa yellow and ofa blue dyestuff in order to produce greens
• transfer materials which have been printed with inks containing such mixtures of dyestuffs are also within the scope of the pres ent invention.
• mixture of dyestuffs are in fact used then it is necessary to use mixtures of at least two dyestuffs of each colour present in the ink, one dyestuff of each colour differing in the degree of volatility from the other dyestuff or dyestuffs of the same colour.
• one dyestuff of each colour differing in the degree of volatility from the other dyestuff or dyestuffs of the same colour.
• at least two yellow dyestuffs which give a similar shade but differing degrees of volatility
• at least two blue dyestuffs which give a similar shade but of differing degrees of volatility.
• the less volatile dyestuff could be a homogeneous violet dyestuff whilst the more volatile dyestuff could be a mixture of a red and a blue dyestuff (which mixture is of the same shade as the violet dyestuff) which, whilst they are more or less volatile than the violet dyestuff volatilise at substantially the same rate.
• the dyestuffs giving a similar shade or shades, but of differing degrees of volatility, used to obtain the transfer papers of the invention differ from each other by a r factor of at least 10 seconds where I is the time required to achieve 50% penetration of a carpet pile when carried out under the following conditions, the degree of penetration being principally related to the volatility of the dyestuff.
• one dyestuff can have a r factor of 15 seconds and the second dyestuff, which gives a similar shade to the first, will then have a r factor of at least 25 seconds. If a third dyestuff giving a similar shade is also present then this will have a factor which is at least 10 seconds greater than that ofthe second dyestuff. Preferably the difference in the t factors of the dyestuffs of similar shade is at least seconds.
• the disperse dyestuffs used to obtain the transfer materials of the invention can be of any of the recognised classes of disperse dyestuffs, in particular of the azo, anthraquinone, nitro and quinphthalone series such as are commercially available or are described in, for example, the third edition of the Colour Index which was published in 1971.
• Such dyestuffs are normally the commercially available forms containing considerable amounts of dispersing agents and/or other diluents, but the corresponding pure dyestuffs (i.e. free from dispersing agents and/or diluents) can also be used, particularly in the case of inks based on organic liquids as the liquid media.
• the substrate for the transfer materials of the invention is preferably paper, but, if desired, other substrates such as aluminium foil can be used.
• the substrate can be porous or non-porous.
• the inks required for the production of the transfer material of the invention can be obtained in conventional manner, for example by milling together a mixture of the dyestuffs, a binder or resin, a liquid medium, and optionally additional components such as dispersing agents.
• Water can be used as the liquid medium, but it is preferred to use an organic liquid or mixtures thereofffor example hydrocarbons such as toluene, xylene and aliphatic petroleum fractions which boil in the region of 80 to 200C, alcohols such as isopropanol, ketones such as methylethyl ketone, and esters such as methyl acetate.
