Appeal No. 95-0761
Application 08/050,511
THE INVENTION
Appellant claims a dry transfer graphics article which has, in order, a backing film, a
release coating, a continuous brittle polymeric film, and a pigmented pressure sensitive adhesive in
a pattern, such that when the adhesive is bonded to a substrate and the backing film is pulled away
from the substrate, the polymeric film fractures along the borders defining the pattern and only the
portion of the polymeric film attached to the adhesive transfers with the adhesive to the substrate.
Appellants also claim a method for making the article by applying each of the layers of the article
and curing the article. Claim 1 is illustrative and reads as follows:
1. A method for preparing a pressure sensitive dry transfer graphics article for application
to a bonding substrate comprising the steps of:
a) applying, to a backing film comprising a first face and a second face, a release coating
to said first face;
b) applying to said release coating a continuous film of brittle polymeric compound;
c) applying in imagewise fashion to said polymeric film a pigmented pressure sensitive
adhesive coating to form a graphic pattern; and
d) curing said article formed by steps (a) through (c);
whereby, upon application of said pressure sensitive dry transfer graphics article to the
bonding substrate by pressure applied to the areas defined by said graphic pattern, said pigmented
pressure sensitive adhesive is transferred to the bonding substrate and, after peeling said article
away from said bonding substrate, said polymeric film fractures along the borders defining said
graphic pattern such that the polymeric film in union with said graphic pattern is transferred with
said pressure sensitive adhesive to the bonding substrate and the polymeric film not in union with
said graphic pattern remains with said release coating.
