Definitions

  • This invention relates to the production of gumrned paper having thereon an adhesive coating of the re moisten-able type.
  • the invention has particular relation to control of the common tendency of gurnrned paper to curl on itself, especially when exposed to varying conditions of humidity.
  • a water-soluble glue is coated on a base sheet in the usual way from solution, the coating tends to dry or set as a more or less continuous film and will inherently have some tendency to curl or roll the coated sheet on itself.
  • a continuous film is exposed to humidity, and particularly to a range of varying conditions of humidity, it will absorb or lose moisture to a substantial extent, and t s increases its curling actions. This result can be extremely undesirable, especially in the case of multiple sheets of gunirned paper such as may be used for labels and the like.
  • a common practice for eilecting some degree of control or elimination of the above curling problem is to break up the dried glue film into multiple particles by rtuining the uncoated side of the sheet over one or more breaker knives.
  • This treatment is fairly eli'ective in eliminating the initial tendency of the gununed sheet to curl, but it represents an extra step in the production of the sheet, and also it has a definite tendency to damage the uncoated surface of the sheet on which printing is later to be applied in the case of label paper and the like.
  • the breaking treatment is not effective in preventing subsenuent curling of the sheet upon exposure to humidity, since the resulting absorption of moisture tends to coalesce the broken sections or" the film into a continuous film which causes the sheet to curl.
  • the present invention proposes a solution to the difficulties outlined above by the provision of a remoistenable gummed sheet whereon the adhesive coating is of a composite character which inherently prevents curling even if the rernoistenable component of the coating does abso b moisture upon exposure to varying conditions of hurrloi More specifically, the coating of the invention comprises a major roportion of a Water-soluble glue which is dispersed in essentially powder form in a binder material which is relatively insensitive to changes in humidity conditions and which is present in sufilcient proportion to retain the glue particles together on the sheet but in maintained separated form.
  • the glue component should preferably have minimum solubility in the binder material even when the latter is in a fused condition from exposure to heat or a solvent other than water, since otherwise there mi ht be a gradual tendency for the glue particles to coalesce even if the film could initially be produced as outlined above. It should therefore be possible to dissolve the binder material in a solvent in which the glue itself is not soluble, but it it is attempted to produce a coatable dispersion by means of "ice such a selective solvent, it then becomes necessary to eliminate such solvent from the coated film, and this procedure may involve factors of considerable expense as well as safety.
  • the solvent is reclairnable, it is necessary to determine as a matter of economics whether it is preferable to provide equipment for recovering the solvent or to treat it as expendable.
  • the solvent vapor is toxic or inflammable, it is essential in any event to provide for its control, and all such factors contribute to the cost of the ultimate product.
  • such fusing action has been obtained by heating to soften the binder material as well as by exposing the coating to the vapor of a solvent which Will fuse the binder material without atlecting the glue, and it has also been found desirable to subject the coated sheet to a calendering treatment before or in conjunction with the fusing step to compact the powdered glue in the resulting film.
  • the invention is applicable to a wide variety of binder materials and is not limited by the degree or" solubility of the binder material in water.
  • highly satisfactory results have been obtained by means of the invention in conjunction with a highly water-soluble glue such as dextrin or animal glue and a substantially water-insoluble binder material such as rosin or polyvinyl acetate.
  • the binder material initially adheres the glue particles together and to the base sheet but prevents them from coalescing in the absence of sufiicient moisture to effect the reversal of phase described above.
  • the binder material becomes dispersed in the continuous glue phase, and since it is present only as a minor proportion of the total composition, it does not adversely altect either the adhesive grab or the permanent adhesive properties of the film.
  • the invention has the further practical advantage of making it possible to obtain adhesive coatings of effectively uniform physical and adhesive characteristics with relatively simple equipment.
  • the invention provides for initial deposit of the powder coating by means of a technique of electrostatic precipitation which assures a uniform layer on the base sheet without precision doctoring equipment.
  • the subsequent fusing step can also be carried out with simple equipment, such as heated rolls or a relatively small hooded chamber for treatment with solvent vapor, and there is no necessity for prolonged drying treatments, solvent recovery apparatus, and the like.
  • the method of the invention is not limited to use with binder materials which are water-insoluble, and it can be practiced with equal facility in conjunction with water-soluble binder materials capable of production in essentially powder form either alone or in the presence of the glue which forms the main constituent of the composition.
  • the invention offers the same advantages discussed above when practiced with water-soluble binder materials, particularly as compared with production of the films from a dispersion of the glue in a solution of the binder material, since the latter require both the availability of a suitably selective solvent as well as subsequent controlled elimination of such solvent from the film with the attendant difliculties pointed out above.
  • 'It is particularly an object of the invention to provide a method producing a gummed sheet having the characteristics outlined above which does not require a solu- .tion of any of the constituent materials of the adhesive coating and in which therefore it is unnecessary to pro vide for the subsequent elimination or recovery of a solvent.
  • Another object of the invention is to provide a method as outlined above in which the several constituent materials may initially all be produced and mixed in powder form as well as applied to the base while still in powder form, and in which the binder material is fused on the base sheet to adhere the powdered water-soluble glue particles together and to the base sheet.
  • An additional object is to provide a method as outlined above wherein the mixed powdered constituent materials are deposited on the base sheet by a technique of electrostatic precipitation providing a coating which is of essentially uniform characteristics without the necessity of doctoring or metering and which is readily converted to a homogeneous film by fusion of the particles of binder material therein while maintaining the main adhesive constituent dispersed therein in powder form.
  • a further object is to provide a method as outlined above which is especially adapted for including in the adhesive composition a powdered material having a modifying action thereon such, for example, as a material which reacts therewith in the presence of water to make the composition water-insoluble and thus to prevent sub- 7 sequent removal by water of the gummed sheet from a surface to which it has been attached.
  • FIG. 1 is a diagrammatic representation of a gummed sheet constituting a preferred embodiment of the invention.
  • TFIG. 2 is a diagrammatic illustration of a preferred method in accordance with the invention for producing the product of FIG. 1.
  • this invention is ap-' plicable'to the production of gummed sheets whereon the adhesive coating includes either a water-soluble or a water-insoluble binder material for the'powdered'watersoluble glue, but in general the invention appears to have wider applicability to the production of such coatings wherein the binder material is eifectively water-insoluble.
  • One explanation for this result is the fact that such binder materials are inherently less sensitive to humidity, and particularly changes in humidity conditions, than water-soluble binder materials.
  • the paper web 10 is shown as being fed from a supply roll 11 into one end of a coating chamber 13.
  • the mixed powders are also shown as supplied to the chamber 13 from :a hopper 15 from which a chute 16 connects with the output pipe 17 leading from a blower 18 to the bottom of the chamber 13.
  • This arrangement provides for conveying the mixed powder into the chamber 13 in generally cloud form while at the same time tending to break up any agglome-r ates.
  • An effectively uniform powder coating of substantial thickness is therefore caused to adhere to the sheet 10, which leaves the chamber 13 over a guide roll 25.
  • the coated sheet passes from the guide roll 25 to a pair of calender rolls 27 and 28 for the purpose of compacting the powder coating without disturbing the temporary adhesion thereof for the paper web.
  • the Web then passes t a'station 36 at which the compacted coating is treated in such manner as to fuse the binder material while maintain ing the glue in powder form.
  • the station 30 may comprise a roll or bar heated to a temperature suffi cient to fuse the binder material, or it may be a substantially closed chamber supplied with vapor of a solvent for the binder material which is a non-solvent for the glue,
  • the coated Web may be re-wound as indicated at 33.
  • the binder may fuse to more or less of a network form, which may in fact be porous, but with the binder material, including whatever plasticizer may be present, forming a homogeneous film.
  • the binder may actually be in such network form, for the purposes of the invention, it functions as the continuous phase of the coating prior t the subsequent application of moisture.
  • the binder may under some conditions form a completely c ntinuous film, particularly when the pressure applied in conjunction with the fusing step is adequately high.
  • animal glue is a water soluble adhesive having high adhesive grab when wet as Well as strong adhesive properties after drying. It is readily reducible to a fine powder by simple treatment such as grinding, and it also has the practical advantage of low cost. Similar properties are possessed by dext-rin, which has also been used successfully as the water-soluble glue component in the production of gumrned sheets in accordance with the invention.
  • the polyvinyl acetate in Example I is the binder mate rial along with the Sant-icizer 9, and two of its advantages for use in the method of the invention are its insolubility in Water, which makes it insensitive to humidity conditions, its substantially lower melting point than animal glue, which renders it easy to fuse by heating without afifecting the glue.
  • the Santicizer 9 in Example I is employed as a solid plasticizer for the polyvinyl acetate, with which it combines to produce a softer than would otherwise be obtained. At the same time, it is similarly grindable to powder, and it will fuse under substantially the same conditions as polyvinyl acetate. in addition, it also has substantially no solvent action on the animal glue.
  • the relative proportions of the constituent materials for an adhesive composition in accordance with the invention are determined primarily by practical conditions. For example, there should be as much of the Watersoluble glue as possible while still maintaining the desired insensit vity of the him to changes in humidity conions. This is desirable for a number of reasons, ineluding attainment of maximum Wet tack and permanent adhesion as well as minimum tendency of the film to block under normal storage conditions prior to activation. On the other hand, maximum sensitivity and reaction to a subsequent moistening treatment is assured by a high percentage of glue, especially when the binder material is Water-insoluble as in Example I. Also, since the glue is by a considerable margin the least expensive compo nt of the compoistion, the total cost is reduced by a hi :1
  • the ratio of binder material to glue should be as low as practicable while still assurins maintained separation of the glue particles in the film prior to activation by moisture.
  • proportion of resin to plasticizer is determined by practical considerations, and ordinarily the minimum amount of plasticizer would be used as required by the desired properties of the film as a whole as well as the compatibility of the plasticizer and resin. Having these various considerations in mind, the following are other examples of satisfactory compositions produced from the same constituent materials:
  • Example 11 Parts Animal glue 82 Polyvinyl acetate 12 Santicizer 9 6
  • Other plasticizers have been used in similar pnoportions with similar results including triphenyl phosphate, diphenyl phthalate, and Santicizer 1H (n-cyolohexyl-ptoluene sulfonamide).
  • dextrin can be substituted satisfactorily for the animal glue in the above examples, and other water-insoluble binder materials have also been used in the practice or" the method of the invention, as illustrated by the following compositions:
  • Example IV Animal "lue Rosin (or snellac) 30 Carbowax 600$ (polyethylene glycol) 10
  • Example V Parts Animal glue 80 Rosin 20
  • Example VI Parts Animal glue 70 Sorbitol (polyhydric alcohol) 30
  • Example VIZ Farts Animal glue (or pregelatinized dextrin) 6G to 65 Sorbitol to Polyvinyl methyl ether/maleic anhydride half amide 10 Since the binder material in each of Examples VI and Vii is water-soluble, the sheets coated therewith do have a greater tendency to absorb moisture when exposed to high humidity than do the coatings containing Watchinsoluble bin ers such as those in Examples 1 and V.
  • compositions of this character can also be produced and coated on base sheets by the method of the invention, and an example of a sheet of such composition is as follows:
  • Example VIII When the constituent materials of Example VIII are ground, mixed and applied to the sheet as described in connection with FIG. 2, the tannic acid tends to remain suspended in the binder material and generally in inactive, condition. However, when the coating is subsequently moistened for use, the tannic acid will react with the animal glue and cause it to become essentially waterinsoluble, although this reaction will not interfere with the adhesive grip and permanent adhesion of the composition.
  • the method of the invention is thus applicable to a wide variety of adhesive formulations, and it offers similar advantages in practice with all such formulations.
  • the ability in accordance with the invention to prepare and deposit the several constituent materials under conditions minimizing the possibility of their interaction, and particularly of coalescing of the particles of water-soluble adhesive prior to the desired activation thereof, is especially advantageous in obtaining the main objectives of the invention in conjunction with the further advantages of the elimination of the necessity for recovering or otherwise disposing of a solvent in the course of the preparation of the sheets.
  • the deposition of the mixed powdered constituents by electrostatic precipitation as described is also especially advantageous, particularly from the standpoint of the:

  • a non-curling gummed paper including a base having adhered thereto a dry non-tacky water-activatable adhesive coating, said coating comprising a dispersed phase of discrete solid particles of a water-activatable adhesive and a plastically extensible exterior phase which binds the particles to one another and to the paper, said 8 exterior phase including as the essential ingredient a polymeric material which in itself is insoluble in water and which remains insoluble subsequent to the activation of said dispersed adhesive by water, and the proportion of said polymeric material being coordinated and correlated with the proportion of said adhesivernaterial to maintain said adhesive particles adhered to each' other and to said base in separated form in the absence of water while' providing an exposed portion of said adhesive particles for activation upon the application of water to said coating.
