21). “Typical thermoplastic hot melt adhesives include polyamides,
urethanes, polyesters. Typical thermosetting materials include epoxies,
polyimides, cyanoacrylates and urethanes.” (Schlueter, col. 6, ll. 21-24).
“The adhesive layer may comprise any known adhesive for layers of an
electrostatographic imaging member” (Schlueter, col. 13, ll. 63-64).
10. Schlueter does not teach using two different glues with the respective
properties recited in the plain language of independent claims 1 and 18
(Schlueter, passim).
11. Hings teaches a surfacing treatment for a sheet material that is an
application of a thermosetting resin and may be for the purpose of
protecting the sheet from the weather. “In this respect it is similar to
varnish or paint applications on a surface of a sheet and for this purpose
the thermosetting resin may be pigmented.” (Hings, col. 2, ll. 57-63).
12. Hings discloses a first set of nozzles 51 and 52 which are provided with
a mixture of thermosetting resin and catalyst, which emit sprays 53 and
54 to spray or coat facing surfaces 40 and 41, respectively. A mixture of
thermosetting resin and chemical promoter is supplied to a second set of
nozzles 56 and 57. These nozzles emit sprays 58 and 59, which partially
overlap with sprays 53 and 54 respectively, to spray or coat facing
surfaces 40 and 41, respectively. (Hings, col. 6, ll. 47-63, Fig. 2).
13. The combination of catalyzed resin and promoted resin generates heat
that speeds the curing of the resin, so that the cure period may be in the
range of minutes or even seconds. (Hings, col. 6, ll. 10-13)
