Definitions

  • the present invention relates to a non-carbon copy paper, and more particularly to a no-carbon copy paper using an improved base paper.
  • Norcarbon copying paper is widely used for slips and the like. Basically, it has a mouth cap containing a hydrocarbon-based internal phase oil obtained by dissolving a colorless basic dye. Paper consists of upper paper with the base material smeared on the back side of the base paper and lower paper with the acid substance smeared on the base paper surface. And dye-containing microphones Mouth: Medium paper with 7 ° cells smeared on the front and back, respectively. A cell (self-coloring sheet :) in which the above acidic substance and the dye-containing microcapsule are smeared on the same surface is also well known. In recent years, spot printing (No., 1 ° coating) by printing on a printing press has become more and more popular, rather than using a full coat with a coater.
  • n-sheet set Printed carbon paper set in the order of [upper paper + (n-2 :) medium paper + lower paper) is placed over a height of several 10 COT and cut into one section. The parts are applied in several places. After drying, the paper surface is glued in the required set (upper paper + medium paper, medium paper + medium paper, medium paper + lower paper), and between sets that do not require contact (lower paper and upper paper). Paper) is not attached, so it is easy to take out a set of n sheets.
  • This gluing suitability is important, but there are many problems that the adhesive strength in the set is weak or the gluing between sets occurs. Was rare.
  • self paper such as high quality paper (n-1 :) self paper, self paper on paper, etc.). Combinations, etc.) have increased, and it has been easy to raise a problem with the suitability for attachment.
  • the applicant of the present invention has examined the suitability of gluing, mainly from a paper surface, and has already obtained a cuff in Japanese Patent Application No. 55-14863. It has been proposed to add a surfactant to the cell surface to improve the gluing suitability.
  • An object of the present invention is to improve the gluing aptitude of copy paper made of carbon.
  • the inventor of the present invention has proposed that a non-smeared surface of a non-carbon coated base paper to be supplied to a non-carbon copied paper having one side coated with a microcapsule or an acidic substance. It has been found that the use of base paper that has been treated with water-repellent or water-repellent properties greatly improves the gluing suitability of non-carbon-copied copying paper, which used to be a lot of conventional products. I went out.
  • the base paper for a non-carbon copy paper is usually a high-quality paper (although there is also a medium-quality paper recently), and is basically a general printing paper. Is the same as form paper, but has a variety of grades in thickness, basis weight (weight), hue, etc. The desired smoothness, size, waist, strength (tear) , Tension) etc.
  • Japanese Patent Application Laid-Open No. 48-89913 discloses a method for repelling the surface of a carburized smear.
  • No. 49-1099-118 discloses a method of priming an oil and a method of forming a layer of an alkaline substance under an acidic substance.
  • Priming cuff protector cuff discloses a method of smearing the cell, the method of applying a thermal adhesive to one side in JP-A-54-105, and the method of applying a base paper or capsule layer in JP-A-50-8911
  • Japanese Patent No. 54-150210 there is known a method of undercoating a class of clay for the purpose of Paulpen Hajime.
  • the present invention is characterized in that one side of the base paper surface is made to be water-resistant and / or water-repellent for proper bonding.
  • water-resistant is used for papermaking and means that the paper keeps its original shape even after it has been soaked in water and then dried. Water resistant fe hardly appears when using easily soluble materials. There are various methods for testing water resistance, but it is known to be the easiest method. ⁇ Etraf by Finger method. (Wet Ru3 ⁇ 4) Test The force is described in the TAPPI and ASTM methods. Qualitatively, it can be easily determined by rubbing the surface of the tongue with a finger soaked in water.
  • O PI Water repellency is also a term widely used in the papermaking industry, and it is used in the contact angle method, the contact angle method, and the water repellent tester. Tester) is a method to measure the wettability of paper.
  • Water resistance and water repellency are originally different things, for example, the addition of a water repellent results in improved water resistance, and the addition of a water repellent makes water repellent. In many cases, they have substantially the same effect. Collectively, they are sometimes referred to collectively as waterproofing agents.
  • smear a chemical (polymer) that has strong water resistance by itself, or to smear it by itself but adding another water-proofing agent.
  • the former can be exemplified by a water-dispersible polymer, e.g., emulsion, and the like. Alkali-soluble resin is converted to a volatile alcohol such as ammonia. It is also known to dissolve with calipers, smear, dry, etc. to provide water resistance. ''
  • polyhydric metal ions are used as the water-proofing agents, and aldehydes and epoxies that utilize the reaction of a reactive group are used as representatives. be able to.
  • water-resistant polymer examples include polyurethan, poly (norogeneic) olefin polymer, and maleic acid polymer (maleic acid). Resin, or ammonium salt such as styrene-maleic anhydride copolymer) and vinyl acetate. Coalescence, SBR resin, acryl resin, special PVA resin, special starch derivatives such as dialdehyde starch, power epoxy resin, etc. Ammonia salts of polymers having a hydroxyl group are commercially available as water-resistant polymers.
  • water-resistant agent examples include boric acid, aluminum, glucose, calcium ion, and holmium. Lin, ku, aldehyde, aldehyde, glyoxal, urea-formalin resin precondensate, melaminformalin resin precondensate, polyamid Additives such as dopechlorohydrin additives, polyols (glycerin, polyethylene glycol, etc.), epoxy compounds, etc. , Starch oxide, and ester phosphate.
  • Starches such as starch, aluminized starch, etherified starch, polyvinyl alcohol, cellulose derivative ⁇ :, maleic anhydride resin, Usually used in combination with acrylamide resin, acrylic acid resin, polyester resin, etc. Appropriate additives and catalysts can be used based on conventional techniques to speed up water resistance or to increase the stability of the liquid.
  • a general water-repellent chemical used for paper coating can be used, but a typical example is a wax semaphore. Wear.
  • Various types of emulsions are commercially available depending on the type of the box. Silicon oil ⁇ Nora ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ' Keten dimer, metal soap and the like are also used to impart water repellency.
  • the non-carbon paper for copying paper according to the present invention has a non-smeared surface (a surface of an upper paper, a back surface of a lower paper, etc.) subjected to a water-resistant and / or water-repellent treatment, and the surface to be smeared later.
  • a non-smeared surface a surface of an upper paper, a back surface of a lower paper, etc.
  • a water-resistant and / or water-repellent treatment characterized by no water resistance and no water or water repellency treatment, and the most typical production method is to use a size press on a paper machine. Size.
  • the coating and machinery of the dress can smear different liquids, such as roll coaters, valves and blade coaters. The reason for this is that in the next coating process, it is often not desirable to have a water-resistant or water-repellent undercoat for the smeared surface, but at least It is often useless and wasted below.
  • Pigments, dyes, and the like can be added to the liquid to be treated for water resistance or water repellency as needed.
  • the effects of the present invention can be easily understood.
  • the combination used is mainly of water-based high molecular weight or water-based emulsion, so if the surface of the paper is made water-repellent, the glue will be poorly wet and will not adhere easily. Therefore, it is considered that the suitability for gluing was improved.
  • spot printing It is suitable for gluing in cases. Spot printing differs from full-face coating with a coater, and is part-coating (spot printing) of only the necessary parts. In many cases, this is different from the case where high quality paper is piled up. In this case, there is no peeling between the sets, of course, and the whole is bonded in one block shape.
  • spot-on paper and spot-down paper using the base paper for the non-carbon paper according to the present invention are used, the medium in the spot is printed on both sides by spot printing. General high-quality paper is used), and peeling is performed between the lower paper and the upper paper, and it is possible to paste each set.
  • the use of the non-carbon copy paper base paper of the present invention has a remarkable effect in the case of self paper. That is, in the case of conventional self paper, between the non-smeared side (high quality paper) and the self side and the non-smeared side (back side of the self side) and the non-smeared side (high quality paper) Although it was difficult to make a difference between the peeling property and the adhesive property, by making the water-repellent surface of the present invention, the suitability for bonding is greatly improved.
  • Example 1 base paper (Example 1 base paper) was obtained.
  • a commercially available resin spot ink was printed on a flexo printing press, and a cabsell spot ink was printed on a similar flex printing press, using Examples 1 and Comparative Example 1.
  • Spot printing was performed on the surface of the base paper, and the sheets were overlapped by about 10 cm each as a set of two sheets so that the colored surfaces matched. Depending on the base paper used, these were used as the multi-set copy paper of Example 1A and Comparative Example 1A.
  • Example 2 In the same manner as in Example 1 except that 1-styrene maleic anhydride and ammonium salt were used instead of the binder resin, a non-carbon composite paper was prepared. Produced.
  • Example 1 dendine oxide: 7 ° and polyamide epichlorohydrin resin were replaced by ester pentaphosphate: 7 °.
  • a base paper for copy paper of carbon black was prepared in the same manner as in Example 1 except that 0.3 polyethylene glycol was used.
