The particles will more preferably have dimensions of from about 2 to about 10 micrometers.
  • the thermoplastic polymer can be any thermoplastic polymer which meets the criteria set forth herein.
  • the powdered thermoplastic polymer will be selected from the group consisting of polyolefins, polyesters, and ethylene-vinyl acetate copolymers.
  • the thermoplastic polymer preferably excludes tackifiers such as alicyclic hydrocarbons, terpene, or rosin. Tackifiers are heat activated resins used to solidify an image on printed matter.
  • Tackifiers generally refer to convertible polymer systems upon the application of energy, such as heat. Resins and rosins tend to irreversibly harden upon the application of heat energy. Therefore, tackifiers tend to be more like thermosetting materials rather than thermoplastic materials. Therefore, most preferably, the transfer material of the invention includes polymers that are thermoplastic in nature rather than thermosetting-type materials (e.g. thermosetting tackifiers) .

  • the term "melts" and variations thereof are used herein only in a qualitative sense and are not meant to refer to any particular test procedure. Reference herein to a melting temperature or range is meant only to indicate an approximate temperature or range at which a polymer or binder melts and flows under the conditions of a melt -transfer process to result in a substantially smooth film.
  • melt behavior of polymers or binders correlate with the melting requirements described herein. It should be noted, however, that either a true melting point or a softening point may be given, depending on the nature of the material. For example, materials such as polyolefins and waxes, being composed mainly of linear polymeric molecules, generally melt over a relatively narrow temperature range since they are somewhat crystalline below the melting point.
  • Melting points if not provided by the manufacturer, are readily determined by known methods such as differential scanning calorimetry. Many polymers, and especially copolymers, are amorphous because of branching in the polymer chains or the side- chain constituents. These materials begin to soften and flow more gradually as the temperature is increased. It is believed that the ring and ball softening point of such materials, as determined by ASTM E-28, is useful in predicting their behavior. Moreover, the melting points or softening points described are better indicators of performance than the chemical nature of the polymer or binder.
