Definitions

  • This invention relates to transfer printing and more particularly to a transfer material for use in coloring ceramic ware by transfer printing.
  • Transfer printing has been in wide use for coloring ceramic ware on a mass production basis.
  • the technique of transfer printing employs a transfer material, which typically comprises a substrate or base, a design layer including a design to be transfer-printed and a layer interposed between the substrate and the design layer to enable separation of the design layer from the substrate and subsequent adhesion of the design layer to the surface of an article to be transfer-printed when transfer printing is conducted.
  • One method (I) involves applying glaze:on the surface of unglazed ceramic ware, firing the ware at about 1300°C, transfer printing a colored design on the glazed surface of the ware and again firing the ware at about 800°C to 1200°C
  • Another method (II) involves transfer printing a colored design on the surface of unglazed ceramic ware, firing the transfer-printed ware at about 500°C to 700°C, applying glaze on the colored surface of the ware and then firing the ware at about 1300°C.
  • a third method (III) involves applying a mixture of glaze and synthetic resin on the surface of unglazed ceramic ware, transfer printing a colored design on the applied layer of the mixture, and then firing the ware at about 130 0 °C.
  • transfer material that can be used in the above-mentioned methods of transfer printing
  • the material is moistened and swollen with water to render the design layer separable from the substrate, and manually applied to the surface of an object to be transfer-printed so that the design layer is transferred from the substrate to the surface of the object.
  • This type of transfer material is not suitable for use in transfer printing on a mass production basis since it requires much manual labor. Moreover, this type of transfer material cannot be used in the above-mentioned methods (II) and (III) wherein the surface of the piece of ceramic ware is in such a condition as to absorb much water thereby to prevent transfer of the design layer from the substrate layer to the ceramic surface.
  • a transfer material particularly intended for use in the above-mentioned methods (II) and (III) has been proposed, which comprises a sheet of Japanese paper as a substrate or base and a design layer formed thereon by the gravure process with ink for coloring ceramic ware, with a water-soluble resin used as a binder.
  • the transfer material When the transfer material is pressed against the surface of an object to be transfer-printed, the material is moistened with water applied to the reverse side of the base sheet of paper so that the design layer is separated from the base sheet and transferred to the surface of the ceramic ware.
  • This type of transfer material also requires much manual labor and it is quite difficult to effect complete transfer of the design layer and a considerable degree of skill is required if this type of transfer material is used on a curved surface.
  • U.S. Patent No. 3967021 Another type of transfer material is disclosed in U.S. Patent No. 3967021, which comprises a design layer including the design to be transfer-printed, a pair of adhesive layers between which the design layer is laminated, and a substrate layer supporting the three laminated layers.
  • the two adhesive layers are heat-sensitive and activatable within different temperature ranges.
  • the transfer material is heated to a temperature within one of the two temperature ranges so that one of the adhesive layers is activated to cause the design layer to be transferred to the transfer pad, and when the design layer is to be transferred from the pad to an article to be transfer-printed, the temperature drops within the other of the temperature ranges so that the other of said adhesive layers is activated to cause the design layer to be transferred from the pad surface to the surface of the article.
  • the two steps should be conducted either in two different chambers the temperatures inside which are maintained within the above-mentioned respective ranges, or separately at a certain time interval, that is, first at a first temperature within one of the two temperature ranges and after a time interval at a different temperature within the other of the temperature ranges. In either case, the process is time-consuming and not suitable for mass production.
  • the primary object of the invention is to provide a transfer material which is suitable for use in transfer printing a colored design on articles made of various kinds of material.
  • Another object of the invention is to provide a transfer material particularly suitable for use in transfer printing a colored design on pieces of ceramic ware of different contours and shapes on a mass production basis.
  • Another object of the invention is to provide such a transfer material as aforesaid which enables simpler, easier and more delicate coloring of the surface of an object than if conventional types of transfer material are used.
  • a transfer material which comprises a substrate, a first layer of thermoplastic vax-like material formed on the substrate, a second layer of thermoplastic material formed on the first layer, and a design layer formed on the second layer of thermoplastic material with an ink for coloring ceramic ware.
  • the thermoplastic materials of both the first and second layers are not tacky at room temperature but thermally activatable to become tacky and remain so for a predetermined period of time and solidify to effect complete adhesion upon lapse of the predetermined period of time.
  • the materials of the two layers have different softening points and different melting points and are decomposable when burned.
  • the material of the first layer has a higher degree of adhesivity to an object to be transfer-printed than that of the material of the second layer to the pad of a transfer head used for transfer printing.
  • a transfer material 1 is schematically shown in cross section and comprises a substrate 2, a first or lower layer 3 of thermoplastic wax-like material formed on the substrate 2, a second or upper layer 4 of thermoplastic material formed on the first thermoplastic layer 3, and a design layer 5 formed on the second thermoplastic layer 4.
  • the substrate 2 can be a sheet of paper of suitable quality such as coated paper, kraft paper, or a film of a suitable resin- uous material such as polyethylene terephthalate or the like-resinous material.
  • a sheet of paper When a sheet of paper is used as the substrate, it may be thoroughly coated with a material that is both oil-resistant and water-resistant and has no affinity for the thermoplastic wax-like material. Such coating is useful in preventing expansion and shrinkage of the paper and infiltration of the wax-like material into the paper thereby to ensure proper and smooth separation of the layer 3 from the substrate 2.
  • the materials of the two layers 3 and 4 are potentially adhesive and heat-activatable to a state of continuous tackiness.
  • these materials have such a characteristic that they are not tacky or adhesive at room temperature but activated by heating to a state of tackiness, which continues for a substantial period of time even after the application of heat is terminated, and solidify with a required degree of adhesion.
  • the materials preferably are decomposable when they are fired or burned.
  • the thermoplastic wax-like material of the first layer 3 is a mixture of thermoplastic hydrocarbon or rosin as a chief component and wax such as metalized synthesized wax, oxidized modified wax made from montan wax, paraffin wax, microcrystalline wax, animal wax and plant wax, and wax copolymerized with ethylene.
  • Mineral oil, animal oil and/or plant oil may be added to the mixture in order to adjust the softening point, the melting point and the fluidity or viscosity of the mixture, as well as to make easy application of the above-mentioned mixture on the substrate 2 to form the first thermoplastic layer 3 and subsequent formation of the second thermoplastic layer 4 and the design layer 5 thereon and to improve the printing characteristic of the resulting transfer material.
  • the softening point of the vax-like material of the first layer 3 is preferably between 55°C and 60°C and the melting point thereof is preferably between 85°C and 95°C although not restricted to the temperature ranges, with the difference between the softening and melting points being preferably between 25°C and 35°C.
  • hydrocarbon resin suitable for use in the transfer material of the invention can be commercially obtained from Arakawa Chemical Co., Osaka, Japan and the above-mentioned metalized synthesized wax, oxidized modified wax and other waxes can be obtained from Hoechst Corporation, West Germany.
  • the material of the second thermoplastic layer 4 formed on the first thermoplastic layer 3 is a wax-like mixture of was, oil and synthetic resin.
  • the wax are metalized synthesized wax, oxidized modified wax, paraffin wax, animal wax and plant wax, which may be used either individually or in mixture.
  • the oil are mineral oil, animal oil and plant oil, which may be used either individually or in mixture.
  • the resin are thermoplastic hydrocarbon resins and ethylene copolymers, which may also be used either individually or in mixture.
  • the wax-like mixture may be used in the form of emulsion.
  • the thermoplastic material of the second layer 4 may be composed of one or a mixture of two or more of thermoplastic latexes such as styrene-butadienelatex and nitril- butadiene rubber latex; copolymer emulsions of thermoplastic resins such as alkyd emulsion, acrylic ester copolymer emulsion, ethylene-vinylacetate copolymer emulsion, acryl emulsion, and vinylchloride copolymer emulsion; hydrocarbon resin emulsion; and rosin emulsion.
  • thermoplastic latexes such as styrene-butadienelatex and nitril- butadiene rubber latex
  • copolymer emulsions of thermoplastic resins such as alkyd emulsion, acrylic ester copolymer emulsion, ethylene-vinylacetate copolymer emulsion, acryl emulsion, and vinylchloride copo
  • the softening point of the material of the second thermoplastic layer 4 is preferably between 50°C and 55°C and the melting point thereof is preferably between 75°C and 85°C, though not restricted to the temperature ranges, with the difference between the softening and melting points being preferably between 20°C and 30°C.
  • compositions of the materials of the first and second thprmoplastic layers 3 and 4 are so selected that both the softening and melting points of the material of the second layer 4 are lower than those of the first layer 3.
  • the difference in each of the softening and melting points between the materials of the first and second thermoplastic layers 3 and 4 is preferably between 5°C and 15°C though not restricted thereto.
  • the materials of the first and second thermoplastic layers 3 and 4 must be thermally decomposable when fired.
  • compositions of the materials of the first and second thermoplastic layers are also so selected that the material of the first thermoplastic layer 3 has a higher adhesivity to an article to be transfer-printed than that of the second thermoplastic layer 4 to the pad of a transfer head to be described later.
  • the design layer 5 may be formed by offset, gravure, silk screen or any other suitable printing techniques with a suitable ink commonly used for printing and containing colorants, a binder, and other necessary component elements.
  • an additional layer 6 of an elastomeric material such as urethane resin may be formed on or beneath the design layer 5 as shown in Fig. 2 to prevent distortion of the design layer when transfer printing is conducted. If the design is delicate and complex, the protective layer 6 is particularly useful to maintain the original design in the course of transfer printing.
  • a transfer printing process in which the transfer material shown in Fig. 1 is used will now be explained.
  • a sheet 1 of the transfer material as prepared in the above-mentioned manner is provided.
  • the sheet is then heated to such a temperature that the thermoplastic layers 3 and 4 are softened and become tacky.
  • the dual-layer arrangement with the material of the first or lower layer 3 having higher softening and melting points than those of the second or upper layer 4 enables uniform softening and activation of the materials of the two layers and subsequent smooth separation of the layer 3 from the substrate 2 and proper adhesive application thereof to the surface of an article to be transfer-printed.
  • a table 7 provided with an electric heater 8 may advantageously be used for the purpose since the next step of the process can immediately be taken on the heated sheet 1 on the table 7.
  • a transfer head 9 is provided with a pad 9a made of a suitable resiliently deformable material such as silicone rubber and so contoured as to have a convexly curved surface 9b.
  • the head 9 is brought downwardly into contact with the upper surface of the heated sheet 1 of transfer material with a suitable pressure as shown in Fig. 3b, so that as the head 9 is raised, most of the thermoplastic layers 3 and 4 together with the design layer 5 and, if provided, the coating layer 6 are transferred to the surface 9b of the pad 9a as shown in Fig. 3c. Some of the thermoplastic material of the layer 3 is left on the substrate 2 as shown at 3'.
  • the transfer head 9 with the design and other layers on the surface of the pad 9a is brought into contact with the surface of a piece of ceramic ware 10 to be colored or transfer-printed with a suitable contact pressure as.shown in Fig. 3d, so that as the head 9 is raised again, the design layer 5 and the thermoplastic layers 3 and 4 are transferred from the pad surface to the surface of the ceramic ware as shown in Fig. 3e with chiefly the adhesive wax-lika material 3 being in close contact with the surface of the ceramic ware.
  • the layer 4 adheres more strongly to the pad surface 9b than the layer 3 adheres to the substrate 2, and when the layers are transferred from the pad surface to the surface of the ceramic ware 10, the layer 3 adheres more strongly to the surface of the ceramic ware than the layer 4 adheres to the pad surface.
  • This is possible by proper selection of the materials of the substrate and the thermoplastic layers of the transfer material, and by the state of continuous tackiness of the activated thermoplastic or adhesive layers.
  • the ceramic ware 10 with the transferred layers on the surface thereof is fired to such a temperature as to securely fix the design layer to the surface of the ceramic ware while simultaneously decomposing the thermoplastic materials 3 and 4 and removing the burned remnants from the surface of the article, so that the surface becomes clean with the design clearly transfer-printed thereon as shown in Fig. 3f.
  • Coated paper weighing 128 g per square meter is used as the substrate sheet, on which a first layer of thermoplastic wax-like material and a second layer of thermoplastic material are successively formed one upon the other with a mixture of the following compositions.
  • composition of the thermoplastic wax-like material of the first layer is composition of the thermoplastic wax-like material of the first layer:
  • composition of the thermoplastic material of the second layer is composition of the thermoplastic material of the second layer:
  • thermoplastic layer On the surface of the second thermoplastic layer thus formed a design layer is formed by the gravure process with an ink commonly used for coloring ceramic ware and containing inorganic pigments as chief components to produce a sheet of transfer material.
  • the sheet of transfer material is put on a heating plate heated to about 130°C, and a transfer head with a silicone rubber pad is pressed against the upper surface of the heated sheet of transfer material so that as the transfer head is removed therefrom the design layer and most of the thermoplastic layers are transferred to the pad surface of the transfer head.
  • the head is then pressed against the unglazed surface of a piece of ceramic ware so that the design layer and the thermoplastic layers are transferred from the pad surface to the surface of the ceramic ware.
  • glaze is applied to the surface of the ceramic ware, which is then again fired at 1350°C.
  • the ware has now been glazed, with the design having been clearly and securely transfer-printed on the surface thereof.
  • a sheet of transfer material is prepared in the same manner as in Example I by forming on a substrate sheet similar to that in Example I a first and a second thermoplastic layer successively one upon the other with a mixture of each of the following compositions.
  • composition of the thermoplastic wax-like material of the first layer is composition of the thermoplastic wax-like material of the first layer:
  • composition of the thermoplastic material of the second layer is composition of the thermoplastic material of the second layer:
  • thermoplastic layer On the surface of the second thermoplastic layer thus formed a design layer having a delicate flower design is formed by screen printing with an ink commonly used for coloring ceramic ware and on the design layer there is formed a coating of elastomeric acrylic resin.
  • a piece of ceramic ware has its surface glazed and fired, and the sheet of transfer materials prepared in the above-mentioned manner is applied to the glazed surface of the ceramic ware to transfer the design layer from the sheet of transfer material to the surface of the ceramic ware, which is then fired at about 800°C so that the delicate flower design has new been transfer-printed on the glazed surface of the ceramic ware.
