Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR BELT
Document Type and Number:
WIPO Patent Application WO/2008/023677
Kind Code:
A1
Abstract:
An electrophotographic photoreceptor which is excellent in wear resistance
and crack resistance and has a long photoreceptor lifetime can be produced by
using a polycarbonate resin composition prepared by blending 100 parts by weight
of a polycarbonate resin with 0.01 to 5 parts by weight of a silicone-modified
polyurethane obtained by reacting (a) a diol component represented by the general
formula (I) with (b) an active hydrogen containing polysiloxane compound, (c)
a polyisocyanate component and, if necessary, (d) a chain extender as the material
for the backing film of a photoreceptor belt. [Chemical formula 1](I) wherein
R1 and R2 are each independently hydrogen or alkyl; R3
is hydrogen, alkyl, alkoxy, halogeno or alkoxycarbonyl; M is a single bond, substituted
or unsubstituted alkylene, or oxyalkylene; and n is an integer of 0 to 4.
