Definitions
- This invention relates to a recording medium suitably used for the ink jet recording method, particularly to a recording medium having excellent absorptivity and color forming characteristic of an aqueous ink, as well as excellent sharpness of the recorded image obtained.
- the present invention relates to a recording medium which can provide a recorded image with little in-room decoloration of the image and excellent storability of the image and a recording method which can provide the above recorded image.
- the present invention relates to a recording medium having excellent water resistance and light resistance of the recorded image, while having various characteristics as mentioned above.
- the recording medium to be used is required to have the following characteristics, namely:
- the problem of light resistance which has been the problem in the prior art is a problem of fading of the image by irradiation of, for example, UV-ray or visible light, etc., which is raised on any image printed on any kind of paper from papers for PPC in general or fine quality paper to coated papers for ink jet.
- the problem of in-room decoloration as herein mentioned is a problem separate from light resistance which is raised in the image also stored in, for example, a place where no direct sunlight is irradiated, but not raised in the image printed on a non-coated paper such as paper for PPC, etc.
- the method as disclosed in Japanese Laid-open Patent Publication No. 60-49990 is a method for improving light resistance, and no effect can be seen for in-room decoloration.
- the problem of in-room decoloration is a problem inherent in coated paper, and it may be estimated to be a problem caused by the pigment forming the coated layer.
- the coated paper by use of highly active silica as disclosed in Japanese Laid-open Patent Publication No. 56-185690 can give an image with high optical density, while it involves a marked problem of in-room decoloration.
- fillers in general for paper with low specific surface area such as calcium, kaolin, talc, silica, etc. are used, although in-room decoloration may be suppressed, there is now the problem that the image density is lowered.
- an object of the present invention is to provide a recording medium which can give an image of high quality and high resolution which is high in density of the recorded image, and yet excellent in ink absorptivity and color forming characteristic of dye.
- Another object of the present invention is to provide a recording medium which can give a recorded image with good storability, particularly a recorded image with little deterioration due to in-room decoloration and an ink jet recording method for forming such image.
- Still another object of the present invention is to provide a recording medium which has excellent water resistance and light resistance of the recorded image, while having various characteristics as mentioned above.
- a recording medium comprising a surface layer composed mainly of aluminum oxide particles and a lower layer having ink absorptivity.
- the present invention also provides a recording medium, comprising a surface layer composed mainly of aluminum oxide particles and a lower layer having ink absorptivity, and having a Stockigt sizing degree according to JIS-P-8122 of 0 to 15 sec.
- the present invention also provides an ink jet recording medium which performs recording by imparting small droplets of an aqueous ink to a recording medium, wherein said aqueous ink contains an acidic dye and/or a direct dye, and said recording medium comprises a surface layer composed mainly of aluminum oxide particles and a lower layer having ink absorptivity.
- the present invention provides a recording medium, comprising a surface layer composed mainly of aluminum oxide particles containing polyaluminum hydroxide and/or polyaluminum chloride and a lower layer having ink absorptivity.
- the present invention further provides a recording medium, comprising a surface layer composed mainly of aluminum oxide particles with particle sizes of 5 ⁇ m or less provided on a liquid absorptive base paper.
- the present inventors investigated about the relationship between the pigment forming the coated layer which becomes the ink receiving layer and in-room decoloration on the basis of recognition that in-room decoloration is a phenomenon which does not occur on non-coated paper but is generated only on coated paper, and consequently found that the problem of in-room decoloration can occur with difficulty when a specific pigment is used as the pigment which forms the ink receiving layer, particularly the recording surface which captures the dye.
- the first specific feature of the recording medium of the present invention resides in that the surface layer which is the recording surface is formed mainly of aluminum oxide particles.
- the aluminum oxide particles as herein mentioned is produced by the method generally called the Bayer method by calcining aluminum hydroxide obtained by hot caustic soda treatment of bauxite which is a natural ore. Otherwise, there can be also used those produced by the method in which metallic aluminum pellets are subjected to arc discharging in water and then the resultant aluminum hydroxide is calcined, or the method in which aluminum chloride is gasified at high temperature and oxidized in gas phase, or the method in which inorganic aluminum salt (alum, etc.) is decomposed.
- the crystal structures of the aluminum oxide particles have been known to be transitioned depending on the temperature for heat treatment form aluminum hydroxide of the giftsite type, the boehmite type to aluminum oxide of ⁇ , ⁇ , ⁇ , ⁇ type.
- any of these preparation methods and crystal structures may be available.
- the purity of aluminum oxide particles may be different depending on the preparation method, the degree of purification, but those available in the present invention are not limited to one containing 99.99% of aluminum oxide (Al2O3) generally called as high purity alumina, but those containing 80 to 90% or more of Al2O3 may be sufficiently available.
- Al2O3 aluminum oxide
- the aluminum oxide particles to be used in the present invention should preferably have a BET specific surface area within the range of from 60 to 170 m2/g, more preferably from 90 to 170 m2/g. If the BET specific surface area of the aluminum oxide particles exceeds 170 m2/g, the in-room decoloration of the recorded image will become undesirably marked.
- in-room decoloration of recorded image is due to oxidation decomposition of the dye, and when the dye is captured on the surface layer of the recording medium, the dye will be correspondingly susceptible to oxidation by contact with air. Particularly when the dye is captured with a pigment with large specific surface area, the contact area with air becomes the maximum, whereby the in-room decoloration is caused excessively.
- a pigment with a specific surface area of 170 m2/g or less.
- aluminum oxide particles among various inorganic pigments can provide an image with excellent optical density as described above remains to be not clarified, but according to the imagination by the present inventors, it may be considered because aluminum oxide particles have positive charges on their surfaces and also can readily absorb electrically acidic dyes and/or direct dyes, and the paper by use of such aluminum oxide particles can capture more dyes near the surface, namely at the surface layer of the ink receiving layer, and also because the dyes and the aluminum oxide particles are electrically bonded, and therefore the dyes existing near the surface layer are stabilized to be decomposed with difficulty, etc.
- silica is used as the pigment forming the recording surface (surface layer)
- the relationships between the specific surface area of silica and image density and between the specific surface area and in-room decoloration is strong, prevention of in-room decoloration and improvement of image density cannot be compatible with each other, whereby it has been difficult to improve the both at the same time.
- the tendency of the both characteristics to be antagonistic to each other may be similar also in the case of aluminum oxide particles as silica, but when aluminum oxide particles are used, the elevating tendency of image density relative to the specific surface area of the pigment is more marked than silica, having the advantage that a desired image density can be achieved with partices having lower specific surface area (170 m2/g or less) as compared with silica. This is the reason why both prevention of in-room decoloration and improvement of image density can be improved by the present invention.
- the aluminum oxide particles to be used in the present invention have an average particle size preferably of 5 ⁇ m or less, more preferably 3 ⁇ m or less, further preferably 1 ⁇ m or less.
- the image density and the in-room storability can be improved to considerable extent, but yet the image density and the in-room storability have the trade-off relationship.
- the above aluminum oxide particles having an average particle size of 5 ⁇ m or less, more preferably 3 ⁇ m or less, further preferably 1 ⁇ m or less.
- An average particle size exceeding 5 ⁇ m is insufficient for inhibiting in-room decoloration.
- the average particle size as herein mentioned is the particle size under the state where the ink receiving layer is formed.
- the primary particle size of aluminum oxide particle is about 1 nm to 1 ⁇ m, particles forming no secondary particle are preferred in the present invention.
- the average primary particle size of aluminum oxide particles should be preferably 0.5 ⁇ m or less. Those exceeding 0.5 ⁇ m have insufficient ink absorptivity.
- the second specific feature of the present invention resides in that the recording medium of the present invention is constituted of a surface layer containing the above aluminum oxide particles and a lower layer having ink absorptivity.
- the surface layer as herein mentioned is a layer constituting the recording surface, and cannot itself absorb and retain all the ink amount attached, but has the function of adsorbing primarily the dye in the ink and permeates most of the ink solvent to migrate it to the ink absorptive lower layer.
- the recording medium of the present invention includes the embodiment of having a recording surface in which the pigment forming the surface layer and the fibrous material of base paper exist in mixture and/or the embodiment of having a recording surface covered with a surface layer with the maximum thickness of 20 ⁇ m, more preferably 15 ⁇ m or less.
- a preferable amount of the surface layer coated as herein mentioned may be within the range of from 0.3 to 7 g/m2 as the total amount of the pigment.
- the coated amount is less than 0.3 g/m2
- there is no effect as compared with the case when no surface layer is provided while if it is provided in excess of 7 g/m2 or the maximum thickness of the surface layer exceeds 20 ⁇ m, similarly as in the case of the above recording medium (2), there ensue such problems as remarkable lowering in ink absorptivity, lowering in in-room decoloration prevention or generation of paper powder even when the above aluminum oxide particles may be used.
- a more preferable amount of the pigment coated on the surface layer is within the range of from 1 to 7 g/m2, further preferably from 2 to 7 g/m2.
- the maximum thickness of the surface layer as herein mentioned refers to the maximum value in the depth direction of the surface layer in the cross-section of the recording medium, and the amount of the pigment coated is the amount of the pigment coated as the surface layer.
- the amount of the pigment coated in the surface layer is determined according to the method of JIS-P-8128, and can be obtained as the value of the amount of the ash in the whole recording medium from which the amount of ash in the base paper is removed.
- the surface layer is formed mainly of the above aluminum oxide particles, but may also use inorganic pigments known in the art, such as silica, aluminum silicate, magnesium silicate, calcium silicate, calcium carbonate, clay, kaolin, talc, diatomaceous earth, etc., or organic pigments such as urea resin, etc. mixed in the pigment in an amount within the range which does not exceed 20% by weight.
- inorganic pigments such as silica, aluminum silicate, magnesium silicate, calcium silicate, calcium carbonate, clay, kaolin, talc, diatomaceous earth, etc.
- organic pigments such as urea resin, etc. mixed in the pigment in an amount within the range which does not exceed 20% by weight.
- the pigment for forming the surface layer as described above should desirably contain 80% by weight or more of aluminum oxide particles, and when aluminum oxide particles are contained in an amount less than 80% by weight, the image density will be lowered, and also the problem of in-room storability may not be cancelled depending on the kind of the pigment used in combination.
- a recording medium which can satisfy the respective requisite performances can be obtained by providing a relatively minute amount of the surface layer, because it is used in combination with an ink absorptive lower layer as described below.
- the present invention is distinct in its constitutional aspect from, for example, a prior art example comprising an ink receiving layer in an amount as much as 15 g/m2 with the use of aluminum particles having a particle size of 30 ⁇ m on a polyethyleneterephthalate film as shown in Example 2 in Japanese Laid-open Patent Publication No. 58-110287 or an example comprising aluminum particles filled internally in pulp fibers during sheet making as disclosed in Japanese Laid-open Patent Publication No. 58-110288.
- preferable recording medium having ink absorptive lower layer in the present invention may include:
- the embodiment (1) is the most preferred embodiment in the present invention in aspect of the problems of in-room decoloration, paper powder, etc., stability in production or cost.
- the surface layer of this embodiment is constituted of a pigment containing the above aluminum oxide particles and a binder.
- the binder to be used in the present invention may include water-soluble polymers such as polyvinyl alcohol, starch, oxidized starch, cationized starch, casein, carboxymethyl cellulose, gelatin, hydroxyethyl cellulose, acrylic resin, etc. and aqueous dispersion type polymers such as SBR latex, polyvinyl acetate emulsion, etc. known in the art, which can be used either singly or as a mixture of two or more kinds.
- a preferable use ratio (weight ratio) of all the pigments to the binder may be 1/4 to 20/1, more preferably 1/2 to 4/1. If the binder amount is more than 1/4, the ink absorptivity possessed by the coated layer is lowered, while if it is lower than 20/1, powder drop-off of the above pigment from the coated layer becomes undesirably excessive.
- the base paper on which the above surface layer is provided is required to be ink absorptive, having a preferable Stockigt sizing degree of within the range of from 0 to 15 sec., more preferably from 0 to 10 sec., further preferably from 0 to 8 sec.
- a base paper having a Stöckigt sizing degreee in excess of 15 is used, the ink absorptivity of the recording medium as a whole is undesirably deficient.
- the recording medium having the above coated layer provided on the base paper should desirably have a Stöckigt sizing degree within the range of from 0 to 15 sec., more preferably from 0 to 10 sec., further preferably from 0 to 5 sec. If it exceeds 15 sec., most of ink absorptivity depend on the coated layer within the above range, whereby ink absorptivity will be deficient.
- the pulp constituting the base paper is not particularly limited, but it may be composed mainly of wood pulp as represented by LBKP or NPKP known in the art, but synthetic fibers or glass fibers may be also mixed therein, if desired.
- fillers in the base paper to be used in the present invention may include clay, talc, kaolinite, titanium oxide, calcium carbonate, etc. generally employed, and particularly in the present invention, these fillers are contained in an amount of 1 to 20 g/m2, more preferably 2 to 10 g/m2 as calculated on the ash content.
- calcium carbonate is particularly preferable, because the dot shape and the color forming characteristic become good.
- the ash content in the base paper in the above embodiment (1) can be determined by, for example, eliminating the ink receiving layer from the recording medium by use of a good solvent for the binder and determining only the ash content in the base paper according to the method of JIS-P-8128, as the mass of the ash content per unit area of the paper at that time.
- a good solvent for the binder for example, polyvinyl alcohol is used as the binder, and in this case, the coated layer is eliminated by dipping the recording medium in stationary hot water, and then the ash content as the base paper can be determined.
- the base paper to be used in the above embodiment (1) can be made with the use of the above materials optionally together with sheet making aids, sizing agents, yield enhancers, paper force strengthening agents, etc. known in the art, if desired.
- a preferable basis weight of the base paper to be used in the embodiment (1) may be within the range of from 60 to 120 g/m2.
- the recording medium of the embodiment (1) absorbs ink through the base paper, if the basis weight of the base paper is less than 60 g/m2, there may ensue problems such as generation of strike-through or cockling, etc. when high density printing is performed. On the contrary, if it exceeds 120 g/m2, the paper becomes too firm, whereby a problem is involved in conveyability within the recording device.
- the recording medium of the embodiment (2) absorbs ink only with the pigment layer, and therefore is excellent in ink absorptivity and dot shape, thus being suitable for providing images of high resolution and high quality.
- the ink receiving layer comprises a layer constitution of two or more layers and contains an ink holding layer formed primarily of a pigment with larger particle size than the above aluminum oxide particles.
- the ink holding layer is preferably formed mainly of a pigment having an (average) particle size of 5 to 30 ⁇ m, more preferably a silicon containing type pigment, further preferably a synthetic silica, and is arranged lower than the layer containing the aluminum oxide particles constituting the recording surface as described above.
- the specific surface area of the pigment forming the ink holding layer should be preferably larger than the pigment forming primarily the surface layer, more preferably 200 m2/g or higher, also in aspect of ink absorptivity. Also, in aspect of color forming characteristic and ink absorptivity, a constitution with the ink absorption speed of the surface layer which is slow to the extent that ink droplets may be blurred in appropriate sizes and with the ink absorptivity of the ink holding layer being large is preferable.
- the use ratio of the pigment to the binder in the surface layer constituting the recording surface may be preferably 1/3 to 5/1, more preferably 1/2 to 3/1, preferably 1/1 to 10/1 as the total of the ink receiving layer.
- any of the binders known in the art can be used for formation of the ink holding layer.
- the amount of the total ink receiving layer coated may be preferably within the range of from 2 to 50 g/m2, more preferably from 8 to 30 g/m2, with the coated amount of the ink holding layer being preferably larger than that of the surface layer.
- porous silica particles having spherical particle shapes as disclosed in Japanese Laid-open Patent Publication No. 62-183382 can be used.

- a supply calender may be used in the steps.
- the recording medium of the present invention formed as described above has high image density, excellent ink absorptivity and yet excellent characteristics without occurrence of in-room decoloration.
- the polyaluminum hydroxide as herein mentioned is a compound having two or more compounds represented by [Al(OH) 3-a ] in the molecule, including, for example, compounds represented by: [Al(OH)3] n AlCl3 (n ⁇ 2), and the above compounds are commercially availabe under the trade name of paho#2S from Asada Kagaku Kogyo.

- the recording medium of the present invention should preferably contain these compounds in an amount within the range of from 0.01 g/m2 to 5 g/m2. If it is less than 0.01 g/m2, water resistance is insufficient, while if it is contained in excess of 5 g/m2, there are problems such as lowering in ink absorptivity and image density.
- the recording medium of the present invention which uses an aluminum type compound as different from the amine type as in the prior art as the dye fixing agent, has the effect of improving water resistance of the dye, and also has no deleterious effect on light resistance.
- the polyaluminum compound can be used with an amine type dye fixing agent as described above mixed therein, the amine type water resistant agent in this case should be preferably within the range of 70% by weight or less, more preferably 25% by weight or less, of the polyaluminum compound.
