- Patent Document 2 Japanese Patent Application Laid-Open No. 4-348989
- thermosensitive recording medium capable of obtaining a recorded image having high recording sensitivity and high image quality without causing the above problems. Disclosure of the invention
- the above-mentioned subjects are: an undercoat layer containing a pigment and a binder as main components, a colorless to pale basic colorless dye, and a developer which reacts with the basic colorless dye to form a color on the support
- a heat-sensitive recording material provided with a heat-sensitive recording layer, wherein the undercoat layer contains carboxymethyl cellulose having an etherification degree of 0.55 to 0.55; was achieved by BEST MODE FOR CARRYING OUT THE INVENTION
- the undercoat layer in the present invention contains a pigment and a binder as main components, and further contains carboxymethylcellulose. Excellent effects are obtained in the present invention The reason is not clear, but it is considered as follows.
- thermosensitive recording layer when a thermosensitive recording layer is provided on such a subbing layer for recording, it is considered that the thermal energy is not transmitted uniformly, the dots become uneven, and the sensitivity and the image quality deteriorate.
- carboxymethylcellulose used in the present invention has the function of enhancing the water retention of the paint, can suppress the penetration of water into the support, and is presumed to contribute to the formation of a uniform coating layer without unevenness. Ru.
- the degree of etherification represents the average value obtained by substituting the hydroxyl group of cellulose with a carboxymethyl group. The lower the degree of conversion, the more hydroxyl groups there are and the easier it is to hydrogen bond with water molecules, which tends to improve the water retentivity of the coating, but the hydrogen bonding between carboxymethyl cellulose molecules becomes stronger ( It becomes difficult to dissolve in water because of the increase in crystallinity, making the preparation of paints difficult and worsening operability.
- the degree of etherification is preferably from 0.55 to 0.55, more preferably from 0.55 to 0.56, from the balance of the two.
- the degree of polymerization of xylmethyl cellulose is preferably 20000 or less ⁇ , more preferably 500 to “! 500” in consideration of water retention.
- a preferable blending amount is about 0.1 to 5 parts by weight with respect to 100 parts by weight of the pigment. Is more preferably 0.3 parts by weight or more and 2 parts by weight or less.
- Hydroxyethylcellulose is thought to have the effect of improving the fluidity of the paint, and is presumed to provide an undercoat layer that contributes to the homogeneity of the image.
- hydroxietyl cellulose is considered to have the effect of improving the water retention of the paint, and the degree of etherification is preferably 0.8 to 2.0, more preferably 1.0 to 1. 5
- the reason for this is that it is roughly the same as carboxymethylcellulose, and although the degree of etherification is lower and the water retentivity tends to be improved as the degree of etherification is lower, the solubility in water tends to be poor. Although it is reduced, it becomes unfriendly to handle due to its improved solubility in water.
- the degree of etherification of hydroxy cellulose represents the average value of hydroxyl groups of cellulose substituted by ethylene peroxide.
- the present inventors are also related to the degree of polymerization.
- the viscosity of the aqueous solution is important. Specifically, the B-type viscosity of a 2 ° / 0 aqueous solution is 300 m Pa s or less, more preferably 200 m Pa s or less, and if the viscosity of the aqueous solution is too high, coating preparation is difficult become. If it is low, the degree of polymerization will usually be low, and therefore it is necessary to increase the amount used in order to obtain sufficient water retentivity, and a lower limit of about 5 m Pa ⁇ s is considered appropriate.
- Hydroxyethyl cellulose is, for example, a pigment which has been pigment-corrected compared to carboxymethylcellulose (Rule 31)
- the adsorptive power to the metal is tens of times (Reference: T. S. Young and E. Fu., Tappi J. 74 (4): 199 (1991)) It is excellent in water retention (dynamic water retention) immediately below the blade when coating is performed in one.
- the ben ⁇ blade or bevel blade coating method the ben ⁇ is laid with the blade lying and the paint is removed on the surface, and the bevel is raised with the cutting edge, so that pressure is applied to the contact parts.
- the paint is strongly pressed against the base paper, water is likely to be removed from the paint and the paint solidifies.
- paint debris accumulates on the cutting edge, causing streak-like streak leaks (defects on the coated surface) on the coated surface.
- the coating material with high dynamic water retention of the present invention it is difficult for water to penetrate into the base paper immediately below the blade, and solidification of the paint is prevented, so coating of the vent blade and bevel blade is possible. It is suitable and can suppress the occurrence of defects such as streaks.
- carboxymethylcellulose is more abundant in water because it adsorbs less to crevices than hydroxylcellulose. Therefore, it is superior in water retentivity and at all times, especially water retention before blades (static water retentivity). Therefore, by using both of carboxymethylcellulose and hydroxymethylcellulose together, it is considered that a good coated surface can be obtained and the coating suitability of the coating is also improved.
- the action of carboxymethylcellulose and hydroxygetylcellulose is particularly effective when the paint concentration is high and the solidification is more reduced.
- the amount of hydroxyl cellulose used is preferably 0.5 to 5 parts by weight with respect to 100 parts by weight of the pigment in total with carboxymethylcellulose. More preferably, it is desirable that it is 0.5 to 3.5 parts by weight with respect to 100 parts by weight of the pigment. If the amount of hydroxy cellulose used is too small, the water retentivity and fluidity will not be sufficiently improved, and if it is too large, the viscosity will be high and it will be difficult to coat.
- the preferred use of hydroxyl cellulose is pigment 100 weight The amount is 0.3 to 3.5 parts by weight with respect to the parts by weight.
- carboxymethylcellulose and hydroxymethyl cellulose are used in combination in the present invention, it is effective to use one having a degree of polymerization of carboxymethyl cellulose of 1000 or less. If the two are used in combination, the viscosity of the coating tends to be high and the workability tends to deteriorate, and by reducing the degree of polymerization of carboxymethyl cellulose, it becomes possible to further improve the operability.
- a binder such as starch, polyvinyl alcohol, methyl cellulose, a water-soluble polymer such as styrene or maleic anhydride, a styrene / ethylene copolymer, an acrylic acid copolymer or the like can be used.
- Containing synthetic resin emulsion etc. In forming this undercoat layer, the amount of application is about 1 to 15 g / m 2 , using a common coating machine, paper, recycled paper, plastic film, synthetic paper This method is easily carried out by coating on a support of an appropriate material such as, etc.
- any known coating method such as an air one night method, a blade method, a gravure method or a roll coating method may be used. Although it may be used, it is possible to apply a high concentration of coating, so that it is difficult for the paint to penetrate the support, and a uniform layer structure is formed, so that the undercoating layer can be coated by pla Form Door is preferable.
- Examples of the pigment contained in the undercoat layer include (calcined) strong orin, calcium carbonate, aluminum oxide, titanium oxide, magnesium carbonate, amorphous silica, aluminum silicate, magnesium silicate, calcium silicate and the like.
- a calcined kaolin having an oil absorption (based on the JIS K 51 0 1 method) of 80 cc / 100 g to 120 g CCZ 100 g is a thermal recording material having an excellent balance between color development sensitivity and image quality. Is most preferable.
