[Industrial Field of Application] The present invention relates to printing paper that is printed using a xerographic printer or the like, and more specifically, to printing paper that is coated with a self-adhesive adhesive or a pressure-sensitive adhesive on a predetermined portion of the surface of the base paper. It is something. [Prior Art] A xerographic printer is a printer or a copying machine that forms an image on print paper using an electrophotographic method. Furthermore, printing paper has an adhesive layer provided on a predetermined part of the paper surface, and after forming an image, it can be folded or stacked, and the adhesive layer parts can be heated together at room temperature without using an activator. Adhesive using only pressure and used to create sealed letters, postcards, booklets, etc. In recent years, with the mechanization of office processing, there has been an increasing demand for the use of printing paper pre-coated with an adhesive having the above-mentioned properties in xerographic printers or copying machines. However, when using conventional continuous slip paper with a low-tack pressure-sensitive adhesive layer into sheets by simply cutting it into sheets in a xerographic printer, misfeeds, double feeds, paper jams, etc. may occur. Poor feeding and thermal curling after image formation causes poor paper stacking on the output tray. In addition, especially when printing 5,000 to 10,000 sheets with a pressure roll transfer printer, adhesive adheres to the photoconductor, and toner adheres to the photoreceptor, resulting in many black spots on the image forming surface of the paper. A problem occurs that makes it unusable. Even if this method is used, adhesive and toner adhesives adhering to the photoreceptor must be cleaned by wiping with a solvent or the like, which is completely impractical, especially when processing a large number of sheets. In addition, even in xerographic printers other than those using the pressure roll transfer method, the adhesive may contaminate the rubber rolls and belts of the paper feeding device, the cleaning device, the fixing device, etc., causing trouble. [Problems to be Solved by the Invention] The present invention solves the above-mentioned problems with printing paper, and provides printing paper that has excellent running properties and stacking properties, and does not cause troubles due to adhesives adhering to photoreceptors. With the goal. [Means and effects for solving the problem] The present inventor determined that the adhesive adhesion to the photoreceptor is due to the basically high tackiness of the pressure-sensitive adhesive, and has devised various improvement methods. It was investigated. As a result, by using self-adhesive adhesives containing fillers, which are based on natural rubber, synthetic rubber, or other low-crystalline polymers, it is possible to prevent the adhesive from adhering to the photoreceptor and print. Being able to drastically reduce sunspots,
They also found that the adhesiveness after printing could be maintained within a practical range, and completed the present invention. That is, the present invention provides a self-adhesive adhesive in which a lubricant is added to a low-crystalline polymer with or without the addition of a tackifier, and a maximum of 10% by weight of a filler with an average particle size of 5 to 30μ is added to the self-adhesive adhesive. This printing paper is characterized in that an adhesive made of the same material is applied to a predetermined portion of the paper surface of the base paper. The self-adhesive adhesive used in the present invention adheres to synthetic rubbers such as natural rubber, isoprene rubber, styrene-butadiene rubber, and polyisobutylene, and low-crystalline polymers such as acrylic resin, silicone resin, epoxy resin, and styrene resin. Waxes such as paraffin wax, microcrystalline wax, and polyethylene wax; higher fatty acids such as stearic acid and lauric acid;
Contains fatty acids such as stearic acid amide and palmitic acid amide. There are roughly two types of formulations for this self-adhesive adhesive. One is tackifying agents such as conventional rubber-based and acrylic pressure-sensitive adhesives, such as tackifying resins such as rosin, polyterpene resins, petroleum resins, etc.
A certain degree of tackiness is imparted by copolymerization or polymer blending of a soft, highly tackified component with a low glass transition point Tg, and then the above lubricant is blended in a relatively large proportion. The other type does not contain a tackifying component like pressure-sensitive adhesives, but instead mixes a relatively small amount of the above lubricant with low-tack natural rubber, synthetic rubber, or low-crystalline polymer. It is. As mentioned above, pressure-sensitive adhesives include synthetic rubbers such as natural rubber, isoprene rubber, styrene-butadiene rubber, and polyisobutylene, low-crystalline polymers such as acrylic resins, silicone resins, epoxy resins, and styrene resins, as well as rosidine, Tackiness is added to polyterpene resins, petroleum resins, etc. by adding tackifying resins, or by copolymerizing low Tg, soft, high tack components, or polymer blends. For the application of the present invention, the amount of tackifying resin and high tack component must be lower than that of ordinary adhesives. As mentioned above, this adhesive is desired to have the property that when pressure is applied to bring them into close contact, only the adhesives adhere to each other, and that it is difficult to adhere to areas where there is no adhesive. In this respect, natural rubber and isoprene rubber are most preferred because they have high self-adhesion and low stickiness. Furthermore, the present invention is characterized in that the above self-adhesive adhesive contains a filler. As these fillers, inorganic pigments such as silica, kaolin, talc, calcium carbonate, and zeolite, and organic pigments such as urea resin powder, polyethylene powder, phenol resin powder, saran resin powder, and cellulose powder starch particles can be used. The average particle size of these pigments is preferably about 5 to 30 microns. If it is less than 5μ, it will not be effective in preventing adhesion to the photoreceptor unless it is blended in a large amount, and if it is more than 30μ, it will not be properly fixed on the paper when adhesive is applied and will fall off. This becomes a free adhesive that remains on the paper and adheres to the photoreceptor. The amount of these fillers added to the self-adhesive adhesive is 10% by weight.
The following are desirable. If it is more than 10% by weight, the self-adhesive adhesive layer will become weak, and the adhesion of the adhesive to the photoreceptor will increase, or sufficient strength will not be obtained. These formulations are based on the adhesion of the adhesive to the photoreceptor, whether or not adhesive strength is reduced due to silicone oil in the release agent supplied to the fixing roll of printers and copiers during image fixation, and the adhesion required from the usage method after adhesion. Adjust as appropriate depending on usage conditions such as strength. Furthermore, the paint for applying these adhesives to the base paper is selected from water-based and organic solvent-based depending on the manufacturing conditions. When coating the base paper, a coating device such as a bar coater, roll coater, or air knife coater, or a printing device such as flexo, gravure, or silk screen can be used. In the base paper of the printing paper of the present invention, 80% by weight or more of the raw material pulp is bleached hardwood kraft pulp, the pulp freeness (CSF) is 410 c.c. or more, and the added amount of starch is 2 g/m It is desirable that it is 2 or less. In other words, the base paper used in the present invention consists of
It is desirable that 80% by weight or more is bleached hardwood kraft pulp. If the bleached hardwood kraft pulp is less than 80% by weight, it tends to form an unsuitable curl shape when heated in a printer or copier. Further, the softness (CSF) of these pulps is preferably 410 c.c. or higher. For general high-quality paper and continuous slip paper, the pulp beating degree is often set to 400 c.c. or less in order to obtain strength, but this is not desirable because the elasticity of the paper due to humidity increases and curling increases. Paper making is often carried out in an acidic system with a pH of less than 7, but the base paper used in the present invention can also be made in a neutral system with a pH of 7 or higher. Furthermore, starch added to improve strength by internal addition and size press is 2
g/m 2 or less is desirable. Starch is more hygroscopic than pulp, and if it is added in an amount of 2 g/m 2 or more, as in continuous slip paper, curling properties will deteriorate. In addition, in order to stabilize the shape and size of curls, in the paper making process, we control the fiber blend in the wire part and the dehydration conditions in the press part, the difference in surface temperature between the upper and lower dry cylinders in the dry part, and the number of nips in the calendar. Alternatively, subtle controls such as nip pressure control are implemented. In addition, physical curling may be corrected using a decurler during the winding and cutting process. Moisture control is also carried out in the manufacturing process to stabilize curling properties, the product moisture is properly adjusted, and moisture-proof packaging is used to maintain it. Furthermore, in order to maintain appropriate copy screen image density and prevent background (white paper) stains, conductive agents such as sodium chloride, potassium chloride, styrene-maleic acid copolymer, and quaternary ammonium salts are added to the size press of the paper machine. The surface electrical resistance of the transfer paper (according to JIS, C-2111) was 10 9
10 10 Ω (humidity (RH) 65%, temperature 20°C). In addition, in order to improve the sharpness of the copy image area, the smoothness of the transfer paper (JIS,
P-8119) for 20 seconds or more. Further, the printing paper of the present invention may be perforated, perforated, and printed depending on its use. [Example] Next, the printing paper of the present invention will be described with reference to Examples and Comparative Examples. Examples 1 to 4, Comparative Examples 1 to 5 L-BKP (hardwood bleached kraft pulp) and N-
BKP (softwood bleached kraft pulp 10% by weight) is beaten appropriately and processed using a fourdrinier paper machine using internal chemicals (talc, rosin size, sulfuric acid).
The paper was made at a speed of 450 m/min. In addition, 2 g/m 2 of starch was applied along with a conductive agent (sodium chloride) using a size press of a paper machine. Using this base paper, the adhesive shown in Table 1 was applied in a linear manner using a flexographic printing machine, and then cut into A4 size sheets to print Examples 1 to 4 and Comparative Examples 1 to 4. Got paper. Further, commercially available continuous slip paper was cut into A4 size to obtain printing paper of Comparative Example 5. We conducted running tests on these nine types of printing paper using the FX9700, a laser printer using the xerography method, to determine the occurrence of black spots on copies due to the adhesion of the photoreceptor to the adhesive, misfeeds, double feeds, paper jams, and paper output trays. Running performance such as poor accumulation was evaluated. In addition, a pressure of 120Kg/cm 2 is applied using a sealing machine.
