Description
Invention field
The present invention relates to thermal transfer receiving sheet.More specifically, the present invention relates to have the thermal transfer receiving sheet (hereinafter also be called for short to do " reception sheet material) of high image quality and hi-vision stability, it also has excellent coiling-resistant performance in printing process, nor expensive.
Background technology
In recent years, thermal printer, especially can printing clearly, the thermal dye transfer printing machine of full-colour image more and more receives publicity.The following formation image of thermal dye transfer printing machine: the layer that contains dyestuff of black plate is placed on image receiving layer (hereinafter also be called for short makes " receiving layer ", but it is receiving the resin that contains fixed dye on the sheet material) on, then from heat head (thermal head) or similar device supply heat so that with the dye transfer on the precalculated position of the dye coating of black plate to receiving layer.The China ink plate contains three look dye coatings: yellow, magenta and cyan, or four look dye coatings (if also comprising black).Dyestuff with every kind of color is transferred on the reception sheet material successively repeatedly, obtains full-colour image thus.Because the thermal dye transfer system can realize the high quality graphic record, but also be applicable to from recently popular digital camera and carry out figure punch, so these systems replace the silver salt photography just gradually.
This reception sheet material has the shortcoming of picture steadiness difference, because the dyestuff that is transferred on the receiving layer can be penetrated into down one deck through certain hour, is diffused into then in the substrate and (hereinafter is also referred to as " bleeding "), and the definition of image can reduce thus.
Thereby when attempting to contain the intermediate layer of hollow or foam particle so that make when receiving sheet material and having density that shock-absorbing capacity improves institute's document image or quality by on substrate, forming, this shortcoming becomes outstanding especially (for example, Japanese unexamined patent publication No. open (Kokai) 1-27996 number, Japanese unexamined patent publication No. open (Kokai) 63-87286 number).
For the heat that effectively utilizes the heat head prints, thermal insulation, flatness and resiliency are essential characteristics, and their appreciable impact print image quality and image densities.More particularly, in the process of printing image, receive sheet material and contact by black plate and heat, and, be known as the pressure of the rubber rollers of " platen " (platen roll) from another side.Under the rubber rollers applied pressure, reception sheet material with comfort cushioning performance is very close to each otherly fully attached on the black plate, and can make the even transfer printing of printing ink, to obtain gratifying picture quality, but have the reception sheet material of poor shock-absorbing capacity and black plate when adhering to, receive between sheet material and the black plate that contacts and have the gap, owing to the existence in gap, the transfer printing poor effect of printing ink, thus uneven image produced.Therefore, shock-absorbing capacity is to receive one of most important quality of sheet material.Japanese unexamined patent publication No. open (Kokai) discloses the preferred size of intermediate layer (froth bed) hollow-particle that is used for the printing quality that obtains to improve for 9-99651 number.
Has the shortcoming of the non-constant of picture steadiness by the reception sheet material that provides the intermediate layer of containing hollow or foam particle to make, because the dyestuff that is transferred on the receiving layer can be penetrated into lower floor through certain hour, be easy to be diffused into (bleeding) in the substrate then, the definition of image is reduced.Therefore, the layer (impervious barrier) with high barrier property energy is essential, to prevent the bleeding phenomenon, particularly contains in the reception sheet material of (hollow or foam particle are contained in this intermediate layer) of intermediate layer.
Japanese unexamined patent publication No. open (Kokai) has proposed following method 6-227159 number: aspect ratio is provided on the priming coat of hollow-particle (intermediate layer) is the floor that contains layered inorganic pigment of 5-90 containing, to prevent the infiltration of solvent for use in receiving layer coating composition or the receiving layer coating composition.Yet therefore layer dyestuff penetration that is not enough to prevent to form image that contains the layered inorganic pigment of this aspect ratio in above-mentioned scope almost do not show the antiseepage chromatic effect in intermediate layer or substrate.One of its reason may be that unlike the infiltration of solvent for use in receiving layer coating composition or the receiving layer coating composition, for dyestuff used in the heat of sublimation transfer printing, the infiltration of dyestuff takes place in the molecule rank.Can prevent bleeding by the coverage that increases impervious barrier.Yet the excessive raising of impervious barrier coverage can reduce the insulation effect in intermediate layer, has reduced printing density thus, and therefore produces unclear image.Along with replacing silver salt shooting art in recent years, exist having the more demand of the reception sheet material of high image quality and superior picture steadiness, these targets need higher technology.

Preferred forms of the present invention
The present invention is described now in more detail.
The inventor has developed multiple impervious barrier material in order to overcome the bleeding problem of above-mentioned hot dye transfer image.Polyvinyl alcohol and acrylic copolymer resin can form film on the intermediate layer, but when the printed sheet material that has formed this film on it is placed wallet or pocket for a long time, perhaps when its during outdoor being moistened by rain, image can produce tangible bleeding phenomenon.That is to say that under the height wet condition or when directly contacting with water, above-mentioned resin does not show enough barrier performances, and so can not prevent bleeding.Highly cross-linked urethane also is known, and it has the high barrier property energy usually, but when trial with it during as impervious barrier of the present invention, will become is difficult to form film on the intermediate layer, therefore, can not show enough barrier performances.Although can realize the formation of film by significantly improving coverage, and can therefore reduce the image bleeding, the hardness of urethane resin has also reduced shock-absorbing capacity and has damaged picture quality, and in serious situation, can make layer cracking and produce the outward appearance of being on duty mutually.Urethane resin also is expensive, is disadvantageous at economic aspect therefore.Therefore the inventor explores the method for utilizing layered pigments to solve the bleeding problem.Because a large amount of tireless researchs are found, can show tangible antiseepage chromatic effect by in impervious barrier, adding swellable layered inorganic component.This is the superelevation degree of crystallinity owing to swellable layered inorganic component, and it makes hot dye transfer to pass through.Correspondingly, by on the intermediate layer abreast this swellable layered inorganic of lay component to form the multilayer chip layer, simultaneously, by make these swellable layered inorganic components bonded to each other and bonding with polymer compound, obtained tangible antiseepage chromatic effect with the intermediate layer.

Hydro-thermal reaction is the synthetic method that comprises the steps: the aqueous solution or the water slurry high temperature with 100-400 ℃ in autoclave or tubular reactor that contain various raw material (for example silicate, magnesium salts, alkali metal ion, alkali metal salt and fluorine ion) are under high pressure reacted.Because crystal growth is very slow in hydro-thermal reaction, can not obtain macroparticle usually, and nearly all particle all has the size of 10 to 100 nanometers.But,, also can make 1 micron or bigger particle by hydro-thermal reaction if synthesize with the time of low concentration, low temperature and prolongation.Yet too high production cost is a subject matter in this situation.
Solid phase reaction is following method: make talcum, alkali metal fluosilicate silicide and other raw material temperature range internal reaction a few hours of 400-1000 ℃ to make synthetic mica.Because solid phase reaction keeps original talcum structure (isomorphism metacrystal simultaneously by making migration of element, topotaxy) make mica, so the quality of gained synthetic mica depends on the physical property and the impurity of original talcum, and since fully control element move, so the purity of synthetic mica and degree of crystallinity are lower usually.
Fusion method is following method: make the fusion under the fusing point (for example 1500 ℃) of mica or higher temperature of anhydrous silicate, magnesia, aluminium oxide, fluorine silication potassium, potash or another kind of raw material, slowly cool to crystallization then and make synthetic mica or synthetic imvite.According to selected heating steps, can melt method or interior heat fusing method is finished this method by external hot melting.The external hot melting method of melting is following manufacture method: raw-material crucible wherein will be housed place temperature to be higher than the chamber and the heating of fusing point, transfer to then in the chamber that temperature is lower than fusing point, but because the expense of crucible, this method is very expensive.Interior heat fusing method realizes raw-material heating and melting by electrification in the container of having equipped graphite (carbon) electrode or metal electrode, and it is synthetic that cooling, and interior heat fusing method then is normally used for fusion.Flux synthesis procedure can assign to make the sintetics with controlled particle size by the pulverizing and the size sieves of cooling and crystalline material.Because flux synthesis procedure can use high pure raw materials, and can obtain uniform mixture of raw material by the fusion step, has high-crystallinity from making, the angle of coarsegrain and highly purified synthetic mica or synthetic imvite considers that they are favourable.
