together with Figure 1. The indicia and markings are placed on the
flexible bandages by using any known printing techniques involving
inks. See column 3, lines 20-29, together with Figures 1-9.
The appellants do not argue that these flexible bandages are
not elastomeric bandages. Rather, the appellants argue that there
is no motivation or suggestion to employ the claimed ink
composition to prepare the indicia or markings in Hessel’s flexible
bandages. We do not agree.
The examiner has correctly found that both Miyamoto and Davey
teach various advantages of using the claimed printing ink
composition on plastic substrates or films. Miyamoto, for example,
teaches water-based printing inks containing particles of a
urethane polymer and a pigment for various flexible plastic films,
inclusive of the flexible elastomeric backings used in Hessel’s
bandages. See page 2, lines 1-7, page 7, lines 9-20 and 45-48.
These inks, according to Miyamoto, exhibit strong adhesion and peel
strength to various kinds of plastic films and are good for
occupational safety and food hygiene. See pages 2 and 21. Davey
also teaches using a primer containing polyurethane resin and a
pigment to improve adherence of an ink to a polymeric film and
