Definitions
- This invention relates to printing paper, and in particular to such paper for hard copy sublimation transfer, which may be used for making a hard copy of an image picked up by a video camera or a television picture image by thermal transfer of sublimable dyes.
- hard copies may be obtained by thermal transfer printing by superposing a dye carrier ribbon having a colorant layer, in which sublimable dyes are contained, on to printing paper, and heating the ribbon according to a pattern corresponding to image information, for example, image information picked up by a video camera or television picture image information, thereby causing the sublimable dyes to be transferred to the printing paper.
- FIG. 1 of the accompanying drawings there is shown a printer for obtaining a hard copy by thermal transfer printing.
- the printer has a platen 2 around which printing paper 1 is wound and which is rotated in the direction of an arrow a , and a heating head 4 arranged to press a dye carrier ribbon 3 against the platen 2 and the printing paper 1.
- a heating head 4 arranged to press a dye carrier ribbon 3 against the platen 2 and the printing paper 1.
- heating elements 4a At the tip of the heating head 4 are arranged heating elements 4a corresponding to the number of required picture elements, which in turn correspond to the number of elements in one scanning line of, for example, a television picture image.
- the dye carrier ribbon 3 sandwiched under pressure between the heating head 4 and the printing paper 1 has a sheet substrate 9 on which there are formed colorant layers in a form corresponding, for example, to the frame of a television picture image, and which each contain a respective one of four sublimable dyes which are yellow, magenta, cyan and black in colour.
- the respective colorant layers including yellow Y, magenta M, cyan C and black B are successively formed on the sheet substrate 9 in a repeating fashion.
- detection marks 5 (5Y, 5M, 5C and 5B for each of the respective colorant layers) from which the position of each colorant layer is detected, are provided along one side edge of the substrate 9 as shown.
- a block position-detecting mark 6 is provided along the other side edge of the substrate 9.
- the sublimable yellow dye in the dye portion Y is thermally transferred to the printing paper according to the heating pattern.
- a light source 7 for example an infrared light emission diode
- a photo detector 8 constitute a detector means for detecting the detection marks 5 (5Y, 5M, 5C and 5B) and 6 in order that signals corresponding to the respective colour signals in the dye portions Y, M, C and B are supplied to the head elements 4a of the head 4.
- a system is known, for example, from EP-A- 228294, which forms part of the prior art according to Art. 54(3)(4) EPC.
- Printing paper for transfer-by-sublimation type hard copies has previously been constituted of a substrate such as paper, synthetic paper, a plastics film or the like, with a dye accepting layer formed on the substrate and mainly composed of a polyester resin such as polyethylene terephthalate.
- a polyester resin such as polyethylene terephthalate.
- polyester resins have good exhaustion properties for sublimable dyes and are stable under ordinary storage conditions. Therefore, printing paper with a dye accepting layer mainly composed of a polyester resin such as polyethylene terephthalate has good stability under ordinary storage conditions.
- a preferred embodiment of the present invention provides printing paper for hard copy sublimation transfer having storage stability of picture images made by thermal transfer of a sublimation dye, and having superior dyeing properties with respect to the sublimation dye.
- Printing paper 13 comprises a substrate 11 and a dye acceptor layer 12 formed on the substrate 11.
- the dye acceptor layer 12 may be formed by a single coating layer as shown in Figure 2 or by a multi-layer structure formed of coating layers 12a and 12b as shown in Figure 3.
- the dye acceptor layer 12 ( Figure 2) or the uppermost layer 12a ( Figure 3) is formed of a resin layer mainly composed of a resin having bisphenol units, the resin in the resin layer having a glass transition temperature Tg not lower than 55°C.
- the resin having bisphenol units is used in amounts not less than 70 wt% of the total amount of the resin in the resin layer or the uppermost resin layer. If the amounts are less than 70 wt%, the dyeing property of a sublimable dye and the storage stability are unfavourably degraded.
- the (uppermost) resin layer may further contain, apart from the resin having bisphenol units, up to 30 wt% of other types of resin such as polyesters, epoxy resins, nylon or cellulose acetate resins. In this case, the resin layer should be arranged to have a glass transition temperature Tg of not lower than 55°C.
- the (uppermost) resin layer may further comprise fillers (for example SiO2, TiO2, CaCO3 or the like), ultra-violet (UV) absorbers, antioxidants, fluorescent brighteners, surface active agents and the like.
- fillers for example SiO2, TiO2, CaCO3 or the like
- UV absorbers for example UV, UV absorbers, antioxidants, fluorescent brighteners, surface active agents and the like.
- a resin having bisphenol units has a high absorptivity for sublimable dyes and exhibits good storage stability of picture images formed thereon when the temperature is maintained at or lower than its glass transition point Tg.
- the main component of the (uppermost) dye accepting layer should be a resin having bisphenol units and the layer should have a glass transition point Tg not lower than 55°C, so that stable storage is ensured even under high temperature and higher humidity conditions than in an ordinary state. Accordingly, although, for example, a polyester resin may be mixed with the resin having bisphenol units in order to increase the colour concentration, the resultant resin layer should have a glass transition point Tg not lower than 55°C.
- Phenoate YP-50 (Trade name of Toto Kasei Co., Ltd., phenoxy resin, Tg 100°C) was dissolved in a solvent and applied onto art paper used as a substrate 11 in a dry thickness of 10 ⁇ m, thereby obtaining printing paper 13 for printing hard copies by thermal transfer of sublimation dye, the printing paper 13 being composed of the substrate 11 and a dye accepting layer 12 as shown in Figure 2.
- a resin layer was formed in the same manner as in Example 1 using U-100 (Trade name of Unitika Ltd., polyarylate resin, Tg 190°C), thereby making printing paper 13 which was composed of a dye accepting layer 12 and a substrate 11.
- a resin layer was formed in the same manner as in Example 1 using a mixed resin (Tg 57°C) of 7 parts by weight of Epototo YD-012 (Tg 65°C) and 3 parts by weight of UE-3300 (Trade designation of Unitika Ltd., polyester resin, Tg 50°C), thereby making printing paper 13 composed of a dye accepting layer 12 and a substrate 11.
- a mixed resin Tg 57°C
- Epototo YD-012 Tg 65°C
- UE-3300 Trade designation of Unitika Ltd., polyester resin, Tg 50°C
- Vyron No. 200 (Toyobo, polyester, Tg 67°C) was dissolved in a solvent and applied onto an art paper, used as a substrate, in a dry thickness of 10 ⁇ m, thereby obtaining printing paper for printing by thermal transfer of sublimation dye which was composed of the substrate and a dye accepting layer.
- a resin layer was formed in the same manner as in Comparative Example 1 using XA5535 (made by Unitika Ltd., polyester, Tg 105°C), thereby obtaining printing paper which was composed of a dye accepting layer and a substrate.
- a resin layer was formed in the same manner as in Comparative Example 1 using a mixed resin (Tg 53°C) of 7 parts by weight of Epototo TD-012 (Trade name of Toto Kasei Co., Ltd., bisphenol A-type epoxy resin, Tg 60°C) and 3 parts by weight of TP-219 (Trade designation of Nippon Synthetic Chem. Ind. Co., Ltd., polyester resin, Tg 40°C), thereby obtaining printing paper composed of a dye accepting layer and a substrate.
- a mixed resin Tg 53°C
- Epototo TD-012 Trade name of Toto Kasei Co., Ltd., bisphenol A-type epoxy resin, Tg 60°C
- TP-219 Trade designation of Nippon Synthetic Chem. Ind. Co., Ltd., polyester resin, Tg 40°C
- An ink having the following composition was prepared and applied onto a 10 ⁇ m thick condenser paper substrate in a dry thickness of 1 ⁇ m to make an ink ribbon.
- This ink ribbon was used for printing on the printing papers of Examples 1 to 9 and Comparative Examples 1 to 4 by the use of a thermal head, thereby obtaining print samples. Thereafter, as shown in Figure 4, the printed surface of each print sample was brought into intimate contact with art paper 15 to provide a layer structure 14 which was allowed to stand in atmospheres of 65°C and a relative humidity (R.H.) of 80%, 55°C and a relative humidity (R.H.) of 85%, and 40°C and a relative humidity (R.H.) of 90% for one week, to test for ageing. After the ageing process, the density of dye transferred to the art paper was measured by means of a Macbeth densitometer.
- the (uppermost) dye accepting layer is a resin layer mainly composed of a resin having bisphenol units and having a glass transition point Tg not lower than 55°C. Accordingly, the dyeing property of the dye accepting layer is enhanced, so that an image of a higher quality can be obtained, which has good stability even under high temperature and higher humidity conditions than is the case under ordinary storage conditions.
- This does not require an additional specific type of surface protective film, such as laminate film, as has been necessary with the previously-proposed types of printing paper.
