PURPOSE:To provide a video photographic paper excellent in the light resistance of the image formed by the migration of a dye into its receiving layer. CONSTITUTION:In a video photographic paper on which images are formed through dye migration into its receiving layer consisting mainly of resin by heating the dye supported on a base body or dye-containing ink to fuse or sublime the same, the resin in the receiving layer consists mainly of polyvinyl aromatic carboxylate or its copolymer in mixture with ester or urethane compound added thereto.

CONSTITUTION:In a video printing paper on which images are formed through dye migration into its receiving layer consisting mainly of resin by heating the dye supported on a base body or dye-containing ink to fuse or sublime the same, the resin in the receiving layer consists of the homopolymer or copolymer of benzylmethacrylate and tetrahydrofurfurylmethacrylate and the copolymer of these and other vinyl compound.
Abstract:
PROBLEM TO BE SOLVED: To provide a desired low saturation printed article having no hue slippage. SOLUTION: A heat-transfer sheet has color material layers D 1 , D 2 and D 3 . The value C of equation (1) of a transferred image by respective color material layers, Cn=((an)^2+(bn)^2)^0.5, is respectively less than 12. The colorimetry values P (a * and b * ) of the transferred image by respective color material layers which are obtained by equation (2), (a * )=(ay-ax)/(Ly-Lx) * (38-Lx)+ax, and equation (3), (b * )=(by-bx)/(Ly-Lx) * (38-Lx)+bx are different from the colorimetry value of the transferred image by another color material layer. Cn represents a saturation, a * and b * represent a colorimetry value being equivalent to L * =38, and they are defined by the equations (2) and (3). Lx, ax, bx, Ly, ay and by indicate the colorimetry values of steps Sx and Sy around L * =38 when a stair step-like transferred image is formed. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To assure good transfer of a transfer protective layer without providing a mold release layer while a close contact strength of a thermal transfer dye layer to the base sheet is held in a good state, in a thermal transfer sheet comprising the thermal transfer dye layer and the transfer protective layer in parallel on one side surface of the base sheet. SOLUTION: The thermal transfer sheet comprises the thermal transfer dye layers 2 to 4 and the transfer protective layer 5 in parallel on one side surface of the base sheet 1 in such a manner that the layers 2 to 4 are provided on the sheet 1 via a primer layer 6, and the protective layer 5 is provided directly on the sheet 1.
Abstract:
PROBLEM TO BE SOLVED: To prevent erroneous setting direction at setting an ink jet recording printing paper, in which non-printed regions are separated from a printed region after printing, to a paper feeding tray from developing and to realize the effective utilization of the printing paper. SOLUTION: The ink jet recording printing paper 1 having an ink accepting layer on one side of a base material sheet respectively has the non-printed regions 2b and 2b' at the tip part and the rear end part in its paper feeding direction. In addition, the ink jet recording photographic printing paper 1 has dividing lines 3, by which these non-printed regions 2b and 2b' are separated from the printed region 2a after printing. In at least either one between the non-printed regions 2b and 2b', a notched part 4 is formed so as to distinguish these non-printed regions from each other.
Abstract:
PROBLEM TO BE SOLVED: To prevent the melting of a dye layer, the melting and releasing of a back coat layer and the like. SOLUTION: A thermal transfer film is provided with a base 2, a first bonding layer 3 formed on one face of the base 2, a dye layer 4 formed on the first bonding layer 3, a second bonding layer 5 formed on the other face of the base 2 and a back coat layer 6 formed on the second bonding layer 5. An aluminum chelate compound is added to at least one of the first bonding layer 3 and the second bonding layer 5 of the thermal transfer film 1.
Abstract:
PROBLEM TO BE SOLVED: To indicate correctly the residual amount of an ink ribbon and also to prevent printing with a faulty ink ribbon. SOLUTION: An ink ribbon cassette 8 holds a thermal transfer ink ribbon. A magnetic layer 12 is formed on an end face 10 thereof by applying magnetic coating thereon and the printable number of times is recorded magnetically in the magnetic layer beforehand. In every execution of printing, a microcomputer 22 acquires the previous executed number of times of printing recorded in the magnetic layer 12 of the ink ribbon cassette 8, through a magnetic head 18 and a reproduction circuit 23, and after adding 1 to the executed number of times of printing, records the number in the magnetic layer 12 through a recording circuit 20 and the magnetic head 18. Besides, it reads the printable number of times from the magnetic layer 12 likewise and indicates the difference of this number from the executed number of times of printing in a liquid crystal display device 25, as the residual amount of the ink ribbon 4. Printing is not conducted when the executed number of times of printing reaches the printable number of times.
Abstract:
PURPOSE: To obtain a high-quality image having excellent fixing properties and high saturation by adding a specific clay org. composite and a polymeric hinder to a dye receiving layer. CONSTITUTION: When swellable laminar silicate 1 is swollen in water to add org. cations, for example, quaternary ammonium ions 3 having a water chain, ion exchange is generated and the quaternary ammonium ions 3 are taken in the gaps in layers to form a clay org. composite 4. When the clay org. composite 4 holding the quaternary ammonium ions 3 having water chains between layers is mixed with and dispersed in a non-aqueous polymeric binder to be swollen, compatibility can be applied to the polymeric binder.

PURPOSE: To enhance the saturation of the image on printing paper and to enhance the fixing properties of the formed image. CONSTITUTION: In printing paper wherein a dye receiving layer is formed on a support, the dye receiving layer contains a clay org. composite 4 wherein interlaminar ions X2 of smectite are substituted with ions ionically exchangeable with a cation dye 5 and a polymeric binder and smectite is synthetic smectite 1 represented by formula X0.1-1.0 Mg2.4-2.9 Li0.1-0.6 Si3.5-4.5 O0.5-10.5 (OH and/or F)1.5-2.5 (wherein X is Li ions and/or Na ions being interlaminar ions).
Abstract:
PURPOSE:To improve sensitivity at the time of transfer and the hue and light fastness of an obtained image by making it possible to use a cation dye incapable of being used heretofore as an image forming material in a thermal transfer system. CONSTITUTION:The pair ion such as halogen of a hydrophilic cation dye is exchanged with an org. anion such as a sulfosuccinic acid anion, for example, a diethylhexylsulfosuccinic acid anion, an alkylbenzene sulfonic acid anion, for example, a dodecylbenzenesulfonic acid anion or an alkylsufuric acid anion, for example, a laurylsulfuric acid anion or a soap anion to make the cation dye hydrophobic. An ink layer 3 containing this cation dye made hydrophobia is laminated on a support 2 having a heat-resistant slip layer 1 to obtain a thermal transfer ink ribbon 10.
