Definitions

  • decals may incorporate ornamentation and can be highly attractive.
  • decals are expensive to create and difficult to remove. Because water-soak decals tend to be cumbersome, slow to apply, and difficult to position, pressure-sensitive adhesive decals have come into widespread use. However, either the adhesive must be applied in register with the graphics or some mechanism must be provided to separate the adhesive at the precise outline of the graphics. These requirements are particularly difficult to achieve if the graphics have fine detail.
  • the novel method comprises the sequential steps of
  • the liquid mixture can be applied by any conventional coating technique, e.g., screen printing, spray painting, or knife coating.
  • the graphics can have exceedingly fine detail and may be applied in half tones and multiple colors.
  • the liquid mixture may include pigments, dyes, fillers, and/or other light-altering agents and may also contain ultraviolet light absorbers, antioxidants, flow-control agents and surfactants, some of which may also be light-altering agents. Particulate light-altering agents are preferred, being more resistant than are dyes to the transfer fluids used in step 3). Also, the light-altering characteristics of particulates are less likely to change over periods of time than are dyes.
  • Light-altering particulates may be used in proportions up to the critical pigment volume concentration, but any lesser proportion is viable unless opacity is required.
  • the liquid mixture may comprise solids dissolved or dispersed in a volatile vehicle, whereupon step 2) involves evaporating the vehicle. Instead, the liquid mixture may comprise polymerizable liquid monomers which in step 2) are polymerized in situ to a solid state. Such polymerization can be effected by heating or by exposure to actinic radiation and normally requires a suitable catalyst to be included in the liquid mixture.
  • the flexible, low-adhesion carrier web are polyethylene, polypropylene, polyallorner, and polytetrafluoroethylene films which are known to have low affinity for resin coatings while being highly resistant to fluids which attack the binder resin. Each of these films i.s transparent, which makes it easier to position the graphics on a display surface.
  • Polyethylene is preferred because of its low cost.
  • Other useful plastic films tend to be more expensive than polyethylene and may have low-adhesion coatings which add to their expense.
  • the plastic films may incorporate reinforcing fibers or fabrics. Plastic-coated paper is also useful.
  • the binder resin is a film-forming resin which preferably adheres well to most surfaces but is at least partially dissolved by an economical, readily available transfer fluid such as turpentine or mineral spirits.
  • binder resins include acrylics such as butyl methacrylate, vinyl acetate copolymers, polyamides, polyurethanes, and other resins typically used in paints and coatings to promote adhesion.
  • the binder resin has a Tukon hardness of less than 10.
  • the matrix resin is a film-forming resin which provides a polymeric network that is resistant to transfer fluids which at least partially dissolve the binder resin.
  • Tiie matrix and binder resins shouUi be thoroughly mixed so that the matrix resin will prevent any smearing of the coating of graphics even if the transfer fluid should completely dissolve the binder resin.
  • Preferred matrix resins are polyurethanes, cellulose containing polymers, anci vinyl chloride copolymers. Both the matrix r esin and the binder resin can be polyurethanes due to their wide range of so lub i l i ties . Polyure thanes made from mono-f unctional or low-molecular-weight reactan ts tend to have bette r solub il i ty and hence to be use ful as binder resins .
  • the transfer fluid applied in step 3) may completely dissolve the binder resin or it may merely soften and tackify the binder resin sufficiently to allow a bond to develop when in step 4) the wet graphics are pressed against a display surface.
  • Preferred transfer fluids are characterized by high (above 8.5) or low (below 4.0) hydrogen bonding indices, because they tend not to attack preferred matrix resins. If a transfer fluid does attack a certain matrix resin, that problem can usually be averted by substituting a transfer fluid which may have the same hydrogen bonding index but a different solubility parameter.
  • toluene and turpentine have the same hydrogen bonding index (3.8), but toluene (solubility parameter of 8.9) attacks more resins than does turpentine (solubility parameter of 8.1).
  • the hydrogen bonding index of mineral spirits is 2.2.
  • Other useful transfer fluids include isopropyl alcohol and ethyl alcohol, each of which has a hydrogen bonding index of 8.9. Their solubility parameters are 11.5 and 13.6, respectively.
  • "Penola" 150 which is a mixture of aromatic hydrocarbons having a 65°C flashpoint, a hydrogen bonding index of about 3.0, and a solubility parameter of about 8 .5.
  • the matrix resin may comprise as little as 2% and as much as 50% by weight of total matrix and binder resins, preferably at least 5% when using a transfer fluid that dissolves the binder resin.
  • the proportion of matrix resin is small, the amount of transfer fluid preferably is limited to an amount barely sufficient to wet the entire coating of graphics.
  • the proportion of matrix resin is kept to the minimum that will assure no smearing of the coating of graphics, because high proportions of binder resin insure good adhesion to display surfaces. For this reason, the proportion of matrix resin preferably does not exceed 30% by weight of total matrix and binder resins.
  • the solidified coating of graphics preferably has a thickness within the range of 0.0025 to 0.025 mm. Within that range, the graphics after being transferred to a display surface can have the appearance of exactinglyapplied paint, giving an aura of high quality. Below 0.0025 mm the graphics may involve transfer problems.
  • the carrier web and its coating of graphics provide a graphic transfer medium which can be wound upon itself for storage and shipment and can be used by retail merchants for applying the graphics to display surfaces such as windows.
  • High quality graphics are obtainable, because they can be created at a central location for large numbers of merchants who need only to activate the binder resin with a transfer fluid in order to transfer the graphics to a display surface.
  • the graphics transfer medium of the invention may be most useful in enabling retail merchants to post visual announcements of high quality at low expense.
  • the novel medium should have a number of other important uses. For example, it can be used to apply decorative and functional graphics to vehicular surfaces, and for such use the light-altering agent may comprise retroreflective beads.
  • the novel medium also can be used wherever there is a need for graphics that are not noticably raised above a display surface.
  • Figure 1 is a schematic cross section of a graphics transfer medium of the invention
  • Figure 2 schematically shows the use of the medium of Figure 1 to transfer a coating of graphics to a display surface .
  • a graphics transfer medium 10 shown in Figure 1 includes a flexible low-adhesion carrier web 12 and a coating 14 of graphics. After wetting the coating 14 with a transfer fluid, the medium 10 has been applied to a display surface 20, as shown in Figure 2, and the carrier 12 is being peelea away to transfer the coating 14 of graphics to the display surface.
  • the solids were added to the solvent according to recommendations of the raw material suppliers to yield a screen-printable ink having a viscosity of approximately 2500 cps. This was screen-printed onto a transparent medium-density polyethylene carrier web approximately 0.125 mm thick. The screen printing was a test pattern including the alphabet, various geometric patterns, fine lines, and half tones. The coating was solidified by drying overnight in air to yield a dried thickness of approximately 0.01 mm. Tlic resulting graphic transler medium could be wound upon itself into roll form for storage and shipment.
  • Turpentine transfer fluid was sprayed onto an aluminum panel in an amount barely sufficient to wet its surface.
  • the coating of the medium was placed in contact with the wet surface and firmly rubbed down. After approximately 30 seconds, the polyethylene carrier web was stripped off leaving graphics which appeared to have the same quality as the original test pattern. After drying overnight, the graphics were resistant to scratching, moisture, and sunlight.
  • Example 1 Other specimens of Example 1 were successfully transferred to polyester film, glass plate, polycarbonate sheeting, po lymethylmethacrylate sheet, and baked enamel metal panel.
  • Examples 2-8 Graphics transfer media similar to that of Example 1 were prepared using transparent low-density polyethylene film as the flexible, low-adhesion carrier web.
  • the ingredients of the coatings of graphics are indicated in parts by weight in Tables A and B except that Examples 5-8 included 0.015 part of the siloxane, 0.37 part of the fluorochemical, and 1.485 part of the xylene used in Example 1.
  • the graphics transferred from the medium of Example 4 could be peeled off various display surfaces such as glass plate, polyester film, and lacquered metal.
  • the graphics transferred to such surfaces from the media of Examples 1-3 and 5-8 could not be removed intact.
