bonds strongly to the backing film but can be peeled from it, and should be tough and flexible
(col. 2, line 65 - col. 3, line 12). Arnold does not disclose a release coating, a continuous film of a
brittle polymer applied to the release coating, and adhesive applied imagewise to the continuous
brittle polymeric film.
Hochner discloses a dry transfer material which includes a backing film having thereon a
polymeric coating which preferably verges on being brittle, printed indicia on the surface of the
polymeric coating, and a dry elastomeric pressure sensitive adhesive over the indicia and the
unprinted portion of the polymeric coating (page 2, lines 26-32; page 3, lines 28-31; page 7, lines
14-16). When the adhesive is adhered to a substrate and the backing film is pulled away, the
adhesive shears along the outline of the indicia and the indicia are pulled from the polymeric
coating along with the adhesive to which the indicia are attached (page 8, lines 1-5). Hochner
does not disclose a release coating and adhesive applied imagewise to the brittle polymeric film
such that the brittle polymeric film will fracture along the borders of the adhesive when the
backing film is pulled away from a substrate to which the adhesive is attached.
Rosenfeld discloses a dry transfer article comprised of a backing film having thereon a
polymeric coating which has a low modulus of elongation, indicia applied to the polymeric
coating, and adhesive which may be applied in registration with the indicia (col. 2, lines 40-45).
Rosenfeld teaches that release coatings were known in the art, but that they have disadvantages
which are overcome by his article, wherein the ink is released from the polymeric coating by
burnishing the carrier film (col. 1, lines 41-57; col. 2, lines 17-20; col. 4, lines 2-12). Rosenfeld
