Definitions
- the present invention relates to a recording medium, and particularly to an ink jet recording medium suitable for using in the case of carrying out bidirectional printing using a printer of a serial system.
- the printing speed depends upon the scanning speed of a head.
- the scanning speed of head means “the time until the head returns to the same position").
- the jetting order of inks becomes reverse between forwarding and backwarding, and thus, in bidirectional printing using parallel heads suitable for high speed printing, when the ink-absorbing capacity of the surface layer of an ink-receiving layer is small or the ink-absorbing speed is slow, in the case of printing mixed color images of, for example, red, blue, and green colors, coloring becomes different between the forward path and backward path.
- the ink-absorbing speed mean "the time until attaching an ink droplet to a surface to vanish the ink droplet from the surface").
- JP-A as-used herein means an "unexamined published Japanese patent application”.
- the wetting property of the surface is improved as disclosed in JP-A-63-39373, etc.
- the absorption is insured to some extent but when the resolution is high or a dense image is printed, and also when the directing amount of ink is large, there are problems that because essentially the absorbing amount of inks is insufficient, the inks overflow to bleed images and also because dots are large, only images lacking in sharpness are obtained.
- the present invention has been made in view of the above-described problems, and an object of the invention is to provide an ink jet recording medium which is excellent in the ink absorption, gives a high coloring property of images, does not cause color unevenness and can print images of a high image quality even by bidirectional printing by a high-resolution printer.
- the present inventors have discovered that when a recording medium, wherein the ink-receiving layer has a specific ink-absorbing capacity and the contact angle of ink to the surface of the ink-receiving layer has a specific value, is used, images having a high image quality are obtained and have accomplished the present invention.
- the gist (first embodiment) of the ink jet recording medium of the present invention is an ink jet recording medium in the case of carrying out bidirectional printing using a printer of a serial system wherein inks of at least two colors are mounted in carriages and the nozzle row is disposed in parallel with the main scanning direction of a head, wherein the recording medium comprises a base material and an ink-receiving layer, the ink-receiving layer has an average ink-absorbing capacity of from 10 to 30 cc/cm 2 , and the contact angle of the uppermost surface layer of the ink-receiving layer is from 20 to 60 degree to an ink having a surface tension of from 25 to 72 dyn/cm, whereby the ink jet recording medium as the object of the invention can be provided.
- the ink-receiving layer is composed of at least two layers (that is, comprising at least two layers constituted of an upper layer forming the uppermost surface layer and at least one lower layer) and the ink absorbing capacity of the uppermost surface layer is larger than the ink-absorbing capacity of the lower layer.
- the ink absorbing speed of the uppermost surface layer of the ink-receiving layer is faster than the scanning speed of the head.
- Equation (1) 5 ⁇ m ⁇ A ⁇ 0.7T Equation (2) 1.1 ⁇ L ⁇ La ⁇ 2 ⁇ L, whereby an ink jet recording medium which can print images of a high image quality without causing color unevenness even by, particularly, bidirectional printing using a high-resolution printer can be provided.
- the ink-receiving layer contains a pigment, and the pigment has an apparent specific volume of from 3 to 20 cm 3 /g and is at least one selected from synthetic silica, aluminum hydroxide, alumina, boehmite, calcium carbonate, aluminum silicate, magnesium carbonate, zeolite, and zinc oxide.

- the uppermost surface layer contains a cationic sizing agent in an amount of from 0.2 to 8 parts to 100 parts of the pigment for absorbing an ink.
- the above-described uppermost surface layer is formed by overcoating a layer containing from 0.2 to 3 parts of a cationic sizing agent.
- the cationic sizing agent is made of a styrene-base resin, whereby the contact angle of the uppermost surface layer of the ink-receiving layer can be set to from 20 to 60 degree to an ink having a surface tension of from 25 to 72 dyn/cm, and also the ink jet recording medium, wherein the ink-absorbing capacity of the uppermost surface layer is larger than the ink-absorbing capacity of the lower layer, can be provided.
- the ink jet recording medium of the invention is used for a recording method wherein the resolution is at least 720 x 720 dpi as the tenth embodiment and is also used for a recording method that the maximum jetting amount of ink per one dot is not larger than 15 picoliters (pl) as the eleventh embodiment.
- Fig. 1 is a view for explaining "the printer for carrying out bidirectional printing" and is a plain view of a printing head (seeing from a recording medium side) of the printer.
- a head 1 of Fig. 1 has nozzle rows 2 equipped with nozzles Nz for jetting inks of colors of yellow Y, light magenta LM, magenta M, light cyan LC, cyan C, and black B from the right.
- the nozzle rows 2 are disposed in parallel with the main scanning direction of the head 1.
- the printer (not shown) makes "a bidirectional printing action" of carrying out printing in both actions of the reciprocating motion of the main scanning direction (in Fig. 1, the direction of the direction of an arrow a and the direction of an arrow b).
- a recording medium (not shown) moves to a sub scanning direction crossing at right angle to the main scanning direction.
- the present invention is an ink jet recording medium characterized in that the uppermost surface layer of the ink-receiving layer has an ink-absorbing capacity of from 10 to 30 cc/cm 2 per unit area, and the contact angle of the uppermost surface layer of the ink-receiving layer is from 20 to 60 degree to an ink having a surface tension of from 25 to 75 dyn/cm.
- the ink jet recording medium of the invention comprises a base material and an ink-receiving layer formed on the base material and, if necessary, a ultraviolet ray-absorbing layer, a gloss layer, etc., can be further formed on the ink-receiving layer but in this case, the ultraviolet ray-absorbing layer, the gloss layer, etc., must have a sufficient ink permeability (have a larger ink permeability than that of the uppermost surface layer).
- the ink-receiving layer itself is composed of at least two layers, that is, at least two layers composed of one upper layer forming the uppermost surface layer and at least one lower layer and the ink-absorbing capacity of the uppermost surface layer is larger than the ink-absorbing capacity of the lower layer(s).
- base materials which are hitherto been known such as plain papers, synthetic papers, plastic films, etc., can be used.
- a paper as the base material is a sheet containing a fibrous material and, if necessary, a filler, and papers manufactured by an acidic paper-making method and a neutral paper-making method, which have hitherto been known, can be used.
- the above-described fibrous material constituting the paper is mainly a wood pulp such as LBKP and NBKP and, if necessary, the paper may contain various synthetic fibers, glass fibers, etc.
- plastic film As the plastic film as the base material, known transparent films and opaque films are used.
- the ink-receiving layer in the invention is constituted of at least one layer including the uppermost surface layer made of a binder and a pigment for absorbing inks (hereinafter, is sometimes referred as simply "pigment") as the main constituents, wherein the average ink-absorbing capacity per unit area is from 10 to 30 cc/cm 2 , and the contact angle of the uppermost surface layer of the ink-receiving layer is from 20 to 60 degree to an ink having a surface tension of from 25 to 72 dyn/cm.
- the ink-receiving layer can contain, if necessary, various additives such as a sizing agent, a fluorescent brightening agent, a surface active agent, a defoaming agent, a pH-controlling agent, a mildewproof agent, a ultraviolet absorbent, an antioxidant, etc., in the extent of not reducing the effects of the invention.
- the additives may be mixed with the coating liquid for the ink-receiving layer (so-called internal addition) or may be coated after forming the ink-receiving layer.
- a pigment having an apparent specific volume of from 3 to 20 cm 3 /g is used, and by forming a coated layer, wherein the compounding amount of the binder is in the range of from 20 to 80 parts by weight to 100 parts by weight of the pigment at from 10 to 30 g/m 2 , the ink-receiving layer having an average ink-absorbing capacity of from 10 to 30 cc/cm 2 can be formed.
- the "apparent specific volume” as used herein is measured by a "piston process" disclosed in JIS K 6220, "6.8 Apparent Specific Gravity".
- the contact angle of the uppermost layer can be set to from 20 to 60 degree.
- the average ink-absorbing capacity per unit area is less than 10 cc/cm 2 , the ink-absorbing capacity is insufficient and an ink overflows to cause bleeding on letters and images, which is undesirable. Also, when the average ink-absorbing capacity exceeds 30 cc/cm 2 , an ink permeates too deeply, whereby the reflection density is wholly low such as the dot size is small, images wherein solid black portions are completely filled are not obtained, etc., and the images formed become thin images, which are also undesirable.
- the contact angle of the uppermost surface layer of the ink-receiving layer is less than 20 degree to an ink having a surface tension of from 25 to 72 dyn/cm, the ink permeates fast to the plane direction, which results in that the dot size becomes large and the letters, etc., become thick, and thus images formed become images lacking in sharpness (blurred), and in the other hand, when the contact angle exceeds 60 degree, the drying property of ink becomes slow, unevenness occurs in bidirectional printing, and in an extreme case, rolls of the conveying system are sometimes stained, which are undesirable.
- polyvinyl alcohol derivatives such as polyvinyl alcohol, etc.; proteins such as casein, gelatin, soybean protein, etc.; starch derivatives such as oxidized starch, phosphoric acid esterificated starch, etherificated starch, etc.; cellulose derivatives such as carboxymethyl cellulose, hydroxyethyl cellulose, etc.; various latexes such as a styrene•butadiene copolymer, the polymer or copolymer of an acrylic acid ester and a methacrylic acid ester, an ethylene-vinyl acetate copolymer, and etc.; and polyurethane resin; etc., can be used.
- polymers having a high hydrophilic property such as polyvinyl alcohol, etc., is preferred.
- synthetic silica aluminum hydroxide, alumina, pseudo boehmite, calcium carbonate, aluminum silicate, magnesium carbonate, zeolite, zinc oxide, etc., can be used.
- the specific surface of the pigment for absorbing ink is preferably from 50 to 600 m 2 /g, and more preferably from 100 to 350 m 2 /g.
- the specific surface of the above-described pigment is less than 50 m 2 /g, because the ink-absorbing capacity per unit area is low, the ink-absorbing speed becomes slow and bleeding occurs.
- the specific surface exceeds 600 m 2 /g, the ink absorption becomes good but the binder is also absorbed, which results in weakening the surface strength and easily causing powder falling, which are undesirable.
- the addition amount of the binder to the pigment for absorbing ink is preferably from 10 to 100 parts by weight, more preferably from 20 to 80 parts by weight, and most preferably from 15 to 60 parts by weight to 100 parts by weight of the pigment.
- the addition amount of the binder to 100 parts by weight of the pigment is less than 10 parts by weight, the adhesion of the pigment is insufficient to cause powder falling, and on the other hand, when the addition amount exceeds 100 parts by weight, the void of the pigments is reduced, which results in inferior the ink absorption (capacity and speed) to undesirably cause bleeding.
- cationic sizing agents of a styrene resin-base an alkyl dimer-base (Size Pine K-902, etc., manufactured by ARAKAWA CHEMICAL INDUSTRIES, LTD.), a higher fatty acid-base (NS-815, etc., manufactured by Kindai Kagaku K.K.), a petroleum resin-base (H-7A, etc., manufactured by Kindai Kagaku K.K.), a styrene-acrylic synthetic resin-base (Pearl Gum CS-25S, etc.), etc., can be used, but the use of the styrene resin-base cationic sizing agent is preferred.
- the addition amount of the sizing agent in the uppermost surface layer is, as described above, preferably from 0.2 to 8 parts by weight, and more preferably from 0.5 to 5 parts by weight to 100 parts by weight of the pigment for absorbing ink.
- the addition amount of the sizing agent is less than 0.2 part by weight, the contact angle becomes small and, on the other hand, the addition amount exceeds 8 parts by weight, the contact angle becomes large, which are undesirable.
- the absorption speed of ink of the ink-receiving layer in the invention is faster than the scanning speed of head.
- the purpose is attained by imparting, for example, following both properties to the uppermost layer;
- Equation (1) 5 ⁇ m ⁇ A ⁇ 0.7T Equation (2) 1.1 ⁇ L ⁇ La ⁇ 2 ⁇ L.
- the thickness A is "thinner than 5 ⁇ m"
- the ink-absorbing capacity is insufficient
- the thickness A is thicker than "0.7T”
- the ink absorption is too good, whereby the dot size becomes small and the apparent printing density is lowered.
- La when La is "lower than 1.1 L", the ink-absorbing speed of a lower layer becomes faster, as the case of coating in a large amount by single layer, the dot is not extended but is permeated into the depth direction, which results in lowering the print density. Also, when La is larger than "2 x L", bulks exist and the layer has a porous structure, whereby the strength of the coated layer is weak to cause powder falling.
- the ink-receiving layer wherein the above-described relation is satisfied is obtained, for example, as follows. That is, the ink-receiving layer is obtained by coating a coating liquid formed by adding 50 parts by weight of a binder to 100 parts by weight of a pigment having an apparent specific volume of 5 cm 3 /g as a 1st layer (lower layer) at 10 g/m 2 , coating thereon a coating liquid formed by adding 40 parts by weight of a binder to 100 parts by weight of a pigment having an apparent specific volume of 10 cm 3 /g as a 2nd layer (upper layer) at 6 g/m 2 , and then coating thereon a cationic sizing agent at 0.5 g/m 2 to form the uppermost surface layer, or the ink-receiving layer is obtained by coating on the above-described 1st layer (lower layer) a coating liquid for the above-described 2nd layer (upper layer) added with 1.5 parts by weight of a cationic sizing agent to
