Definitions

  • This invention relates to readily replaceable image graphics.
  • Image graphics are omnipresent in modern life. Images and data that warn, educate, entertain, advertise, etc. are applied on a variety of interior and exterior, vertical and horizontal surfaces. Nonlimiting examples of image graphics range from posters that advertise the arrival of a new movie to warning signs near the edges of stairways.
  • Readily replaceable image graphics are needed for those occasions when the length of time the graphic needs to remain at the intended location is limited to a short duration, often with a replacement image graphic substituting for the image graphic to be removed.
  • An example of an expected replacement image graphic is the movie poster identified above.
  • Readily replaceable image graphics require both the "staying power" when placed on the horizontal or vertical surface and the “leaving ease” when the image graphic is to be removed.
  • films that have an image on one major surface and a field of adhesive on the opposing major surface. Again, movie posters and other bills are often adhered to a surface. If the adhesive is pressure sensitive and capable of being readily removed without leaving adhesive residue, then the poster can be posted with staying power and removed with leaving ease.
  • the present invention solves problems in the art of providing readily replaceable image graphics by avoiding the use of pressure sensitive adhesives on the major surface opposite the image surface yet providing a mating or meshing action with a substrate, i.e., "substrate mating surface".
  • substrate mating surface i.e., "substrate mating surface”.
  • the present invention solves problems in the art by providing an image graphic mating web comprising a major surface comprising an imageable area and an opposing major surface comprising a nonadhesive substrate mating surface.
  • Nonlimiting examples of substrate mating surfaces include surfaces that employ at least one element of mechanical fasteners in mating systems as are marketed under the brands Velcro (Velcro USA, Inc., Manchester, New Hampshire); Scotchmate (3M, St. Paul, Minnesota); and Dual Lock (3M) and as are also disclosed in U.S.
  • the invention uses a mechanical fastener element where the head of the element is larger than the stem in at least one direction traverse to the stem.
  • mechanical fastener elements meeting this description are included in the disclosures and products identified in the paragraph immediately above, and particularly include stem/head mechanical fastener elements such as hooks in the shape of an "inverted J", a "T", and other configurations.
  • the invention is comprised of, but not limited to, a flexible polyolefin material that is shaped on the substrate contact surface into capped posts that resemble mushrooms (referred to herein as "mushroom-type hooks").
  • the imageable surface opposing side is smooth and is capable of being processed to accept an image graphic.
  • Nonlimiting examples of processing capable of making the major surface imageable include surface modification techniques such as Corona
  • the image can be formed by any conventional method.
  • Nonlimiting examples include solvent based inks, 100% solids ultraviolet curable inks, inkjet printing, thermal transfer imaging and electrostatic transfer imaging.
  • An image graphic mating web of the present invention can then be mated to a substrate that has at least a portion of its surface comprising a companion mating element, whether a companion element to a mechanical fastener or a loop structure that interacts with hooks of the substrate mating surface of the image graphic mating web.
  • the nature of mating described as "hook and loop" systems forms the bond.
  • Nonlimiting examples of such systems are disclosed in U.S. Patent Numbers 4,973,326; 5,066,289; 5,077,870; 5,196,266; 5,312,387; 5,316,849; 5,537,722; 5,554,146; European Patent Publication 0 426 359; and PCT Patent Publications WO 9603954 and WO 9621413; and copending, coassigned U.S. patent application serial no. 08/611,351 (Johnson et al.); the disclosures of which are incorporated by reference herein.
  • loop portion of the system can be a conventional material used in a conventional setting, such as carpeting, fabric wall coverings, woven and non-woven materials designed to accept the hook portion of the system.
  • the loop portion can be removably attached to a desired surface.
  • a further advantage of the loop system is that the higher internal strength of many loop systems compared to most films and paper substrates allows the use of a pressure sensitive with higher "staying power", while still affording relatively clean and easy removal.
  • the mating loop can be supplied with any number of pressure sensitive adhesives with various levels of "staying power", to match the characteristics of the underlying surface.
  • the loop can be fastened by alternative methods such as nails, staples, tacks or even wet adhesives in water and/or organic solvents that can be applied by methods such as brushing, troweling, spraying or self-contained aerosol cans.
  • An image graphic mating web of the present invention can be mated with a loop portion and later removed, in order to mount a new graphic. This process can be repeated for the life of the webs, which can vary from a few to thousands of applications.
  • a feature of this invention over the prior art is that the image graphic mating web is designed to be the printable substrate for the graphic.
  • the image graphic mating web does not require a coating of PSA, or a silicone coated liner.
  • the elimination of the silicone coated liner serves two purposes: (a) the liner is an costly component of the graphic film that is discarded after application of the graphic; and (b) a bulky used liner creates disposal or recycling problems for the user of the graphic.
  • the web of present invention produces less waste during production, and less waste during installation.
  • the image graphic mating web is faster to install than a PSA coated graphic, and this method allows for a more predictable removal. While the image graphic mating web does require a loop structure to be applied first, even the need for this step would not involve a significant time penalty to the graphic installer, because the loop is much easier to install than a PSA film graphic. Further, because the loop is hidden by the graphic image, small defects can be tolerated, and larger defects such as wrinkles can be cut out and replaced. In fact, exact placement and squareness are not as critical because the loop can be mounted in a larger size than ultimately needed, and subsequently can be trimmed square to the proper size. After the initial installation of the loop, mounting of the image graphic mating web is extremely fast, even for a novice installer.
  • An image graphic mating web is more easily repositionable and removable.
  • Current PSA graphic films require an expert installer to achieve a defect-free application, and even in the hands of a person skilled in the art, the repositionable feature can be limited. Further, the PSA graphic films can not be removed and reused under normal circumstances, due to the fact that the film is distorted during removal and the fact that the PSA must be protected during storage. In contrast, an image graphic mating web can be mounted and repositioned a number of times until the desired result is achieved. 4.
  • the mechanical fastening aspect of the image graphic mating web allows for maximum bond strength to be achieved immediately, while allowing for easy removal without distorting the graphic long after the graphic has been mounted.
  • Image graphic mating webs also have a number of advantages over the current art of using hook and loop materials for graphic applications.
  • the current art of using mechanical fastening is typified in U.S. Pat. Nos. 4,930,237; 5,024,015; 5,172,504; and 5,482,755.
  • Each of these patents is similar in that small pieces of hook and loop material are added to the finished graphic.
  • the size of the hook and loop fastening varies, or is not specified, but is shown in the drawings typically to be 5% or less of the area occupied by the graphic.
  • image graphic mating webs have a number of advantages:
  • the image graphic mating web is flexible, which makes it easy to transport and install. In comparison, much of the current art requires a rigid graphic web, or a rigid frame, both of which are more difficult to transport. 5.
  • the image graphic mating web is manufactured by a simple polymer extrusion process, where the image receptor layer can be coextruded onto the surface, or can be coated onto the polymer surface at a later time. This process is low waste and economical compared to building up a suitable product by adhesively bonding two or more separate components. Further, since the web is made from thermoplastic materials, recyclablility is enhanced.
  • FIG. 1 is a cross-sectional view of an image graphic mating web of the present invention having an image thereon.
  • Fig. 1 illustrates one embodiment of the invention that shows an image graphic mating web 10 having a substantially continuous backing 12 of thermoplastic resin. Integral with the backing is an array of mushroom-shaped projections or hooks 14, each having a molecularly oriented stem 16, a mushroom head 18, and a fillet 20 at the base of the stem.
  • a piece of the web 10 can be the hook portion of a hook-and-loop mechanical fastener, or it can be releasably fastened to a fabric which is penetratable by the mushroom-shaped hooks 14, or it can be configured such that two pieces of the web 10 can be interengaged to form a hermaphroditic mechanical fastener.
  • the web is substantially shown and described in U.S. Pat. No. 5,077,870, the disclosure of which is incorporated by reference herein.
  • the web 10 has the hooks 14 serving as its substrate mating surface 22.
  • the substantially continuous backing On the opposing major surface, the substantially continuous backing has an imageable surface 24 .
  • An image 26 on at least a portion of surface 24 is shown, while it is to be understood that an image can cover from 0.01-100% of the total area of surface 24 depending on the type of image to be displayed.
  • Mating Surface Mushroom-type hooks 14 are disposed in a selected arrangement (it is preferred that this arrangement be a predetermined pattern) on backing 12, and are formed to have a generally uniform height projection from the backing 12.
  • the selected arrangement for surface stem dispersal is preferably a uniform array, although any arrangement of surface stems is possible (including even a randomly designed dispersal of surface stems within a given area).
  • the mushroom-type hooks 14 are arrayed in staggered rows across the backing 12,. Preferably, each hook of surface stems within a given area). In a preferred embodiment, the mushroom-type hooks 14 are arrayed in staggered rows across the backing 12,.
  • each hook 14 projects at a right angle relative to surface 22, but alternatively angled stem orientations are also contemplated.
  • the mushroom-type hooks 14 and backing 12 are formed integrally, and the web 10 requires no additional support layer or backing material.
  • the hooks 14 of the preferred embodiment are equally spaced apart.
  • the hooks 14 collectively serve to define an operative region or contact surface for mating with the substrate.
  • the hooks 14 provide a very uniform frictional engaging surface for presentation to the substrate to be contacted.
  • the use of uniformly disposed and formed hooks 14 on mating surface 22 results in a highly controllable and predictable engagement relationship between the web and the substrate (e.g., floor, wall, ceiling in an interior or exterior environment).
  • the precisely formed nature of the mating surface introduces a significant mechanical engagement component into the frictional engagement relationship.
  • the upstanding hooks 14 penetrate interstices on the web surface of the substrate (e.g., between the crossed fibers of its weave for a woven web such as carpet or a woven wall covering or a tape affixed to either having a woven outer surface) to engage the web mechanically.
  • the web 10 can be molded from a number of commercially available materials.
  • Nonlimiting examples of moldable material useful for web 10 having hooks 14 thereon include SRD7-560 and SRD70587 impact copolymer resins (available from Shell Polypropylene Company, Houston, Texas); Prevail 3050 resin (available from Dow Chemical Company, Midland, Michigan); Himont KS084P resin (Montell-Himont, Atlanta, Georgia); and Hytrel 5526 or Surlyn 1702 resin (both available from E. I. du Pont de Nemours & Co., Inc., Wilmington, Delaware).
  • stem-shaped projections generally described in copending, coassigned United States Patent Application Serial No. 08/611,351 (Johnson et al.) (incorporated by reference herein) can also be used in this invention.
  • the stems can vary according to a number of parameters. Further aspects of mating surface 22 are described according to a combination of stem height, stem diameter, stem spacing and number of stems per cm 2 . Four examples of these parameters for the web 10 are listed in Table I below:
  • the stem density is preferably greater than 12 stems/cm 2 , and more preferably greater than 15 stems/cm 2 .
  • Table I presents specific stem density examples of 50, 149 and 357 stems/cm 2 , but stem web stem densities greater than 357 stems/cm 2 are also possible.
  • the surface stems may have a height gradient (e.g., shorter in center than near its ends) in order to facilitate handling, the stems may not be round in cross-section, and the stem density and/or stem spacing may vary. In some applications, it may even be desirable that adjacent stems have different heights, or to have stems which change in profile (i.e., cross-section) along their height (e.g., a cylindrical stem having an enlarged, tapered stem base).
  • Web 10 of the present invention is typically formed by molding a flowable material to form hooks 14 seen in Fig. 1 according to the techniques described in U.S. Pat. No. 5,077,870 (Melbye et al.) or stems as described in Application Serial No. 08/611,351 (Johnson et al.).
  • the flowable material can be any suitable material, such as a polymer, a metal or a ceramic precursor. It is also within the scope of this invention to use two or more different flowable materials to make the surface stems, one which can form hooks 14 and the other which can form imageable surface 14.

  • Nonlimiting examples of processing capable of making the surface 14 receptive to imaging include surface modification techniques such as Corona Treatment; liquid coatings dissolved or suspended in either organic solvents or water; or a 100% solids polymeric material that can be extruded or coextruded onto the surface either during or after formation of web 10 as described above.
  • Nonlimiting examples of liquid coatings include ethylene vinyl acetate dispersions, alkyd resins in organic solvent, acrylate and urethane acrylate coatings in water or organic solvents, polyvinyl chloride in organic solvent, and all of the above combined with inorganic materials such as talc, clays, silica and pigments.

  • EXAMPLE 1 Polypropylene material (SRD 70587 from Shell Co., Houston, Texas) was extruded as described with reference to Fig. 3 with approximately 50 pins/cm 2 , and capped into mushroom-type hooks by the methods outlined in U.S. Pat. No. 5,077,870. This material was slit down to 30.5 cm wide rolls, were air Corona Treated on the smooth side at approximately 15 watts/cm (Corona Treater Model DP-9007, Lepel Corp., Maspeth, N.Y.).

  • the Bynel 3101 was extruded at a thickness of 0.003 cm at a melt temperature of 227°C at 6.1 meters/min. The extrusion took place at a heated nip where the Chrome roll was heated to 121°C and the rubber backup roll was kept at 10°C. This was done to maximize the bond between the smooth Corona Treated polypropylene surface and the Bynel 3101, without distorting the hook structure on the reverse side.
  • EXAMPLE 2 The web as prepared in Example 1 was cut into 30.5 cm by 30.5 cm sheets and screen printed with 3M 9715 Red UV Screen Printing Ink. The ink was screen printed using a 390T screen, and cured with a medium pressure mercury vapor focused UN lamp system at 168 mJ/cm 2 . (American Ultraviolet Co., Murray Hill, ⁇ J).
