between the substrate and the charge transport layer is plus or
minus 2 x 10 . See column 5, lines 42-46. The substrate-5
materials may have Tg of less than or greater than 90 C. Seeo
Table 1 at column 6. The substrate can be sensitive to methylene
chloride or can be dissolved or swelled upon contacting methylene
chloride. See Table 1 at column 6. Yu’481 does not describe the
claimed polymers as substrate materials for its electropho-
tographic imaging member. Nor does it recognize the importance
of using substrates insoluble to methylene chloride.
As indicated by the examiner at page 6 of the Answer, Takano
does teach that an alcohol-soluble polyamide, such as nylon-6 and
nylon-66, can be used as an undercoat layer to provide an
electrostatic charge blocking property and an adhesive property.
This teaching is somewhat identical to Yu’s disclosure of a
blocking layer. Yu’ 481, like Takano, teaches a blocking layer,
such as polyesters, polyamides and polyurethanes, which can
function as both an adhesive layer and a charge blocking layer.
See the paragraph bridging columns 6 and 7. However, Takano and
Yu’ 481 do not teach, nor would have suggested, using these
blocking layers as the supporting substrate materials for the
electrophotographic imaging member of Yu’481.
