Definitions

  • the present invention relates to transfer printing, and in particular, to compositions for use in sublimatic transfer printing.
  • Previously proposed sublimatic transfers are used on man-made fabrics, in particular polyester. They are formed by printing an image in sublimatic dye on to a paper carrier or substrate. The image may be formed on the substrate by screen printing, for instance. In order to transfer the image to the fabric, the face of the substrate which bears the image is placed against the fabric surface. Pressure is then applied at elevated temperature, for instance by means of a heated press. This causes the dye on the substrate to undergo sublimation, changing to a gas which impregnates the fabric fibres, where the dye solidifies on cooling. The resultant image is extremely durable by virtue of the impregnation of the dye into the fibres, and is vivid.
  • Natural fibres have a structure which prevents impregnation by sublimatic dyes in a gaseous state, and in consequence only a faint image is produced and the image is easily removed by washing.
  • a composition according to the present invention is characterised by comprising an adhesive component and the material or materials of the composition are so chosen as to be receptive to sublimatic dye transferred thereto by sublimation, and to be adherable to a surface to be printed, thereby binding the dye to the surface to form an image thereon.
  • the composition may comprise an acrylic resin such as n-butyl methacrylate as an adhesive component.
  • the coating may also include a solvent for the adhesive component.
  • the solvent may be a mineral spirit.
  • the mineral spirit may be a dilute benzene based solvent.
  • the composition preferably also includes a plasticizer.
  • the plasticizer may be a phthalate such as butyl benzyl phthalate.
  • the composition when the image is to be formed on a fabric, the composition includes a lubricant for affecting the feel of the transfer after application to the fabric softener.
  • the lubricant may comprise oleine.
  • the composition may include 30 to 50% of adhesive component, 1 to 35% of plasticizer, 10 to 40% of mineral spirit and 1 to 19% of softener.
  • the invention also provides a sublimatic transfer comprising a substrate, an image formed by sublimatic dye, and a coating, the coating and the dye being so selected that on heating to a predetermined temperature the dye transfers the image to the coating by sublimation, the resulting transfer being capable of adherence to a surface to be printed, whereby the coating binds the dye to the surface to form an image thereon.
  • the dye image is preferably located between the coating and the substrate.
  • the coating includes sufficient solvent for the adhesive component to allow removal of the substrate at a temperature in the range 10 to 200°C.
  • the coating is preferably a composition as set out above.
  • the invention provides a method of transfer printing with sublimatic dyes, comprising effecting sublimation of a sublimatic dye on to a coating receptive thereto to transfer an image to the coating, and adhering the coated image to a surface to be printed, whereby the coating binds the dye to the surface to form said image thereon.
  • the sublimation is effected before the coating is adhered to the surface to be printed.
  • the coating is formed over an image which has been applied in sublimatic dyes to a substrate, the method including removal of the substrate after the coated image has been applied to said surface.
  • sublimation of the dye is effected by heating, to transfer the image to the coating before the coating is applied to said surface.
  • the dye may be heated to a temperature in the range 185 to 215°C to transfer the image to the coating.
  • the dye is preferably heated for a period of at least ten seconds to transfer the image to the coating.
  • the coating may be applied to said surface at an elevated temperature to cause the coating to adhere to said surface.
  • the elevated temperature may be in the region of 180 to 220 °C preferably around 190 °C.
  • the coating is preferably applied to said surface under pressure to cause the coating to adhere to the surface.
  • the application pressure may be in the region of 7 to 30 psi, preferably around 20 psi.
  • the elevated temperature and pressure are applied for a period of 7 to 25 seconds, preferably around 10 seconds.
  • the coating is preferably a composition as set out above.
  • the coating to be described is intended for use in sublimatic transfer printing on natural fibres such as cotton and cotton mixtures, for example poly/cotton (polyester/cotton).
  • the coating material consists of four components.
  • An acrylic resin preferably n-butyl methacrylate is used as an adhesive component.
  • a mineral spirit is incorporated as a solvent for the n-butyl methacrylate which is normally a solid.
  • Other suitable solvents include ethers, fluorocarbons, hydrocarbons, ketones and nitroparaffins.
  • a plasticizer, preferably a phthalate such as butyl benzyl phthalate is incorporated to improve the handling properties of the coating.
  • the material also includes a lubricant such as oleine or another animal fat derivative, or a mineral oil derivative, or a mixture of such components. This serves to improve the feel ("handle") of the transfer on the fabric.
  • the composition includes 30 to 50% of n-butyl methacrylate, 1 to 35% of plasticizer, 10 to 40% of mineral spirit and 1 to 19% of lubricant.
  • a composition found to produce acceptable results comprises: n-butyl methacrylate - 48% butyl benzyl phthalate - 8% mineral spirit - 30% lubricant - 14%
  • the formulation of the coating begins by allowing the n-butyl methacrylate to soak in mineral spirit until it softens and dissolves. Gentle stirring at this stage results in a viscous liquid. The plasticizer and lubricant are then added and the resulting mixture is again stirred to an even consistency. The whole formulation process may take place at room temperature.
  • the coating may be applied to a sublimatic transfer 10 which consists of a paper substrate 12A on which an image 12B has been printed in reverse, using sublimatic dyes and a silk screen or other printing process.
  • the coating 14 is then applied, for instance by roller, over the sublimatic dye image 12B which is therefore trapped between the coating 14 and the paper substrate 12A.
  • the image may be transferred to the coating by heating the transfer. Raising the temperature into the range 185 to 215°C for a period of ten seconds is sufficient to cause the dyes to penetrate the coating by sublimation so that when the transfer is returned to room temperature, the image is permanently fixed in the coating.
  • the substrate 12A and dyed coating 14, 12B are placed against the fabric to be printed with the coating 14 in contact with the fabric. Elevated temperature and pressure are then applied.
  • the elevated temperature preferably in the range 180 to 220°C, for example 190°C
  • the applied pressure preferably in the range 7 to 30 psi, for example 20 psi
  • room temperature and pressure are restored, the coating adheres to the fabric fibres, thereby binding the sublimated dyes to the fabric.
  • the durability and vivid colours of sublimatic transfer images can be achieved on fabrics whose fibres are not in themselves suitable for impregnation by sublimatic dye.
  • the formulation described above has the further advantage that, by varying the quantity of solvent included in the coating, the adhesive properties can be varied as may be required to apply the method to different fabrics.
  • the adhesiveness is preferably reduced sufficiently to allow the backing paper to be readily removed at room temperature, or at a temperature in the range 10 to 200°C. Room temperature removal is expected to provide significant advantages when the transfers are used in presses for simultaneously printing a plurality of articles.
  • Previously proposed sublimatic transfers required the backing paper to be removed before the transfer had cooled, so that a press operator may only have a period of a few seconds in which to remove the backing sheets from all of the transfers which have simultaneously been printed.
  • the coating formulation described above has also been found to increase the shelf-life of sublimatic transfers to which it has been applied. Untreated transfers which tend to degrade as the dyes in the image leach into one another. The presence of the coating is believed to inhibit leaching.
  • the use of the coating to bind the sublimatic dye to the surface to be printed allows sublimatic transfer printing to be extended to surfaces which are wholly inpenetrable by sublimatic dyes.
  • the coating may be first applied to the article, following which the dyes are sublimatically transferred to the coating, to be bound to the article.
