"Industrial Application Field" The present invention relates to a heat-sensitive recording material, and particularly to a heat-sensitive recording material having excellent water resistance. "Prior Art" Conventionally, heat-sensitive recording utilizes a coloring reaction between a coloring agent and a coloring agent that develops color when it comes into contact with the coloring agent, and a colored image is obtained by bringing both coloring materials into contact with each other using heat. The body is well known. Such thermosensitive recording media are relatively inexpensive, the recording equipment is compact, and maintenance is relatively easy, so they are used not only as recording media for facsimile machines and various computers, but also in a wide range of fields. On the other hand, with the expansion of the field of use, the number of cases in which heat-sensitive recording bodies are used under conditions where they come into contact with moisture has increased, and the demand for heat-sensitive recording bodies with excellent water resistance is increasing. That is, since thermosensitive recording materials generally use a water-soluble polymer compound as a binder constituting the recording layer, the resulting recording layer has a drawback of extremely poor water resistance. For example, if the recording layer is rubbed with water attached to it, there will be defects such as not only the recording layer falling off but also the recording layer itself peeling off. As a method for improving such defects, for example, a method has been proposed in which a water-soluble polymer compound is used in combination with a water-resistant agent such as potassium alum, formalin, or amide resin. However, when conventionally used water-soluble polymer compounds and waterproofing agents are used together, not only is the sufficient effect not always obtained, but the paint may aggregate during paint preparation, cause fogging, or This causes new problems such as a desensitizing effect and cannot be put to practical use. In addition, a proposal was made to use polyacrylamide as a binder in combination with glyoxal (Japanese Patent Publication No. 1983-
No. 53192), but this method yields extremely unsatisfactory results, especially in terms of water resistance in non-recording areas, probably because curing is insufficient under dry conditions in the normal manufacturing process of heat-sensitive recording materials. Furthermore, a method of providing a protective layer mainly composed of a resin component on the heat-sensitive recording layer has been proposed, but since the resin component is also a normal water-soluble polymer compound, it still has sufficient water resistance. No records are available. "Problems to be Solved by the Invention" The object of the present invention is to provide sufficient water resistance in both recorded and non-recorded areas even when manufactured under normal drying conditions without causing paint aggregation or background fog. It is an object of the present invention to provide a heat-sensitive recording material that can exhibit excellent properties. "Means for Solving the Problems" The present invention provides a heat-sensitive recording material in which a heat-sensitive recording layer containing a coloring agent and a coloring agent that develops a color upon contact with the coloring agent is provided on a support. This is a heat-sensitive recording material characterized by the presence of N-methylolurethanized polyvinyl alcohol in or on the recording layer. "Function" As described above, the present invention has an important feature in that N-methylolurethanized polyvinyl alcohol is selectively used as the binder constituting the heat-sensitive recording layer or the resin component constituting the protective layer provided on the recording layer. It has characteristics. Such N-methylol urethanized polyvinyl alcohol is synthesized, for example, by reacting polyvinyl alcohol with urea under heat to prepare urethanized polyvinyl alcohol, and then reacting this with formaldehyde to perform methylolation. . In the present invention, the urethanization rate and methylol conversion rate of N-methylolurethanized polyvinyl alcohol should be appropriately selected depending on the viscosity of the obtained polyvinyl alcohol, the degree of water resistance required of the applied heat-sensitive recording material, etc. Although not particularly limited, generally 5 to 30% of the vinyl alcohol units in the polyvinyl alcohol molecule are urethanized, and 3% or more of the urethanized vinyl alcohol units are methylolated. Polyvinyl alcohol is preferred. Among these N-methylolurethanized polyvinyl alcohols, polyvinyl alcohols in which 5 to 15% of the vinyl alcohol units are urethanized and 4 to 55% of the urethanized vinyl alcohol units are methylolated are: It is more preferably used because it does not cause problems such as agglomeration of the paint and exhibits sufficient water resistance. The degree of polymerization of polyvinyl alcohol as a raw material is not particularly limited either, but it is generally preferably about 1000 to 2500. Furthermore, the degree of saponification is not limited, and not only fully saponified polyvinyl alcohol but also partially saponified polyvinyl alcohol and the like can be used. The present invention selectively uses N-methylolurethanized polyvinyl alcohol as the binder constituting the recording layer or the resin component constituting the protective layer, as described above, but it may be used as long as it does not impede the effects of the present invention. Other water-soluble or water-dispersible binders can also be used in combination. Examples of such water-soluble or water-dispersible binders include starches, hydroxyethylcellulose, methylcellulose,
Carboxymethylcellulose, gelatin, casein, gum arabic, polyvinyl alcohol, carboxy-modified polyvinyl alcohol, acetoacetylated polyvinyl alcohol, diisobutylene/maleic anhydride copolymer salt, styrene/maleic anhydride copolymer salt, ethylene/acrylic acid copolymer salt Examples include polymer salts, styrene/acrylic acid copolymer salts, styrene/butadiene copolymer emulsions, and the like. In addition, when using N-methylolurethanized polyvinyl alcohol and other binders together,
The proportion of N-methylolurethanized polyvinyl alcohol in the total binder (or total resin component) is
It is desirable that the content be 50% or more, preferably 60% or more. The present invention uses N-methylolurethanized polyvinyl alcohol as described above to make it possible to produce a heat-sensitive recording medium with excellent water resistance without causing paint aggregation or background fog. Furthermore, it is preferable to use a curing agent in combination because a heat-sensitive recording material with even better water resistance can be obtained. Examples of such curing agents include aliphatic dialdehydes such as glyoxal, malondialdehyde, succindialdehyde, glutaraldehyde, adipine aldehyde, maleic dialdehyde, polyamide resins, polyamide resins such as polyamide-epichlorohydrin resin, and glycerin-glycidyl ether resins. , epoxy resins such as sorbitol-polyglycidyl ether resins, melamine resins such as melamine resins, methylol melamine resins, etherified melamine resins, methyl etherified hexamethylol melamine resins, urea resins, urea-formalin resins, dimethylol urea resins, etc. Examples include urea-based resins. Among these curing agents, aliphatic dialdehydes, polyamide resins, and melamine resins are preferable, and glyoxal in particular can provide a thermosensitive recording material with particularly excellent water resistance when combined with N-methylolurethanized polyvinyl alcohol. Therefore, it is preferably used. The amount of the curing agent used is not particularly limited, but is 1% by weight or more, preferably 2% by weight based on the N-methylolurethanized polyvinyl alcohol.
It is desirable to add it in a range of ~60% by weight. In addition, in the present invention, ammonium chloride, magnesium chloride, calcium chloride, aluminum sulfate, magnesium sulfate,
Catalysts such as zinc nitrate, calcium hydroxide, ammonium zirconium carbonate, alkoxides of Ti, Zn, Al, etc. can also be used. In the present invention, the layer structure in which N-methylolurethanized polyvinyl alcohol is present is not particularly limited, and as described above, it can be present either in the heat-sensitive recording layer or in the resin layer provided on the heat-sensitive recording layer. If it is made to exist, the effect can be exerted. Of course, this does not exclude a form in which N-methylol urethane polyvinyl alcohol is present in both the heat-sensitive recording layer and the resin layer, and it is also possible to use N-methylol urethane polyvinyl alcohol in the heat-sensitive recording layer and then add the resin layer to the resin layer. This also includes forms using other water-soluble polymer compounds. In the present invention, there are no particular limitations on the combination of the coloring agent and the coloring agent contained in the recording layer, and any combination that causes a coloring reaction when the two come into contact with each other due to heat can be used. Examples include a combination of a colorless or light-colored basic dye and an inorganic or organic acidic substance, and a combination of a higher fatty acid metal salt such as ferric stearate and a phenol such as gallic acid. Furthermore, it is also possible to apply the present invention to various heat-sensitive recording materials that obtain an eclipsed image (recorded image) by heat, such as a heat-sensitive recording material that combines a diazonium compound, a coupler, and a basic substance. These recording bodies are also included. Various types of colorless to light-colored basic dyes are known, and examples include the following. 3,3-bis(p-dimethylaminophenyl)

In the heat-sensitive recording material of the present invention, the ratio of the color former and color former in the recording layer is appropriately selected depending on the type of color former and color former used, and is not particularly limited. For example, when using a basic colorless dye and an acidic substance, generally 1 to 50 parts by weight, preferably 1 part by weight, per 1 part by weight of the basic colorless dye.
~10 parts by weight of acidic substance are used. To prepare a coating solution containing these substances, generally water is used as a dispersion medium and a ball mill, attaliter,
A coating liquid is prepared by dispersing a coloring agent and a coloring agent together or separately using a stirring/pulverizing machine such as a sand mill. In the present invention, when N-methylolurethanized polyvinyl alcohol is present in the recording layer, the total solid content in the coating liquid is 10 to 70% by weight, preferably 15 to 50% by weight. Thus, such polyvinyl alcohol is added. In the heat-sensitive recording material of the present invention, a sensitizer is added to the recording layer as necessary.

Inorganic pigments such as activated clay, styrene microballs, nylon powder, polyethylene powder,
It is also possible to add organic pigments such as urea/formalin resin fillers and raw starch granules. In the heat-sensitive recording material of the present invention, there are no particular limitations on the method of forming the recording layer, and the recording layer can be formed according to conventionally well-known and commonly used techniques, such as air knife coating, bribber blade coating, pin coating, etc. It is formed by applying and drying a coating liquid using your blade coating, shoot/dwell coating, or the like. The amount of coating liquid applied is not particularly limited, but it is usually 2 to 12 g/dry weight.
m 2 , preferably in the range 3 to 10 g/m 2 . The support on which such a recording layer is formed is generally paper, but it can also be applied to synthetic resin films, laminated papers, synthetic fiber sheets, nonwoven fabric sheets, and the like. On the other hand, in the present invention, when N-methylolurethanized polyvinyl alcohol is present in the resin layer provided on the recording layer, such polyvinyl alcohol is made into an aqueous solution, and if necessary, other water-soluble or water-soluble A coating liquid for the resin layer is prepared by appropriately adding a dispersible binder, a curing agent, an inorganic or organic pigment, a wax, a dispersant, an antifoaming agent, and the like. The amount of inorganic or organic pigment to be used is generally desirably in the range of 5 to 500 parts by weight per 100 parts by weight of the resin component.
The coating liquid for the resin layer prepared in this manner is thoroughly mixed and dispersed using a mixer, attritor, whole mill, roll mill, etc., as necessary, and then applied onto the heat-sensitive recording layer using a known coating device. applied. The coating amount of the coating liquid for the resin layer is not particularly limited, but if it is less than 0.1 g/m 2 , sufficient effect cannot be obtained, and if it exceeds 20 g/m 2 , the recording of the thermal recording material will be impaired. Generally, the dry weight is 0.1 to 20g/ m2 , as it may significantly reduce sensitivity.
Preferably, it is adjusted within the range of 0.5 to 10 g/m 2 . In this way, the heat-sensitive recording material of the present invention, in which the specific polyvinyl alcohol is present in the recording layer or the resin layer, can be produced under normal drying conditions without causing paint aggregation or background fog. It also exhibits excellent water resistance. Note that it is also possible to further improve the storage stability by providing a resin layer on the back side of the heat-sensitive recording material, if necessary. Furthermore, various known techniques in the field of heat-sensitive recording material production may be added as necessary, such as providing an undercoat layer on the support, applying an adhesive treatment to the back surface of the recording material, and processing it into an adhesive label.

A thermosensitive recording paper having a resin layer was obtained in the same manner as in Example 6 except that a 10% aqueous solution of 110 (manufactured by Kuraray Co., Ltd.) was used. The 8 types of thermal recording paper obtained in this way were printed in color using a thermal printer, and the background density and color density were measured using a Macbeth densitometer (manufactured by Macbeth Co., Ltd.,
The results are shown in Table 1. In addition, the water resistance of the non-recorded area and the recorded area was evaluated by the following method, and the results are listed in Table 1. Furthermore, the coating properties (aggregation state) of the recording layer coating liquid and the resin layer coating liquid used in preparing these heat-sensitive recording papers were evaluated, and the results are also listed in Table 1. Method for evaluating water resistance [Water resistance of non-recording area] One drop of water was dropped on the recording layer of the heat-sensitive recording paper before printing, and after 30 seconds, the recording paper was rubbed 10 times with a fingertip, and then the recording paper was dried. Next, to facilitate evaluation, the recording paper was pressed against a hot plate at 130°C for 5 seconds to develop color.
The degree of peeling of the recording layer was visually evaluated. [Water resistance of the recording area] After pressing the thermal recording paper against a 130°C heating plate for 5 seconds to develop color, drop one drop of water on the colored area and heat it for 30 minutes.
After a few seconds, it was rubbed 10 times with a fingertip, and the water resistance of the recorded area was visually evaluated based on the change in color density. [Evaluation criteria] ◎: Very good ○: Good Δ: Slightly poor ×: Poor
