Claims26
A photoreceptor comprising a photogenerating layer of a photogenerating component, a low boiling point solvent, at least one high boiling point solvent, and a resin selected from the group consisting of terpolymers of the formula:
- wherein x is from about 80 percent to about 87 percent by weight,
- y is from about 12 percent to about 18 percent by weight, and
- z is up to about 2 percent by weight of the terpolymer,
- wherein the total of x, y and z is equal to about 100 percent;
- and
- tetrapolymers of the formula:
- wherein R is an alkyl group containing from about 2 to about 12 carbon atoms,
- r is from about 80 percent to about 90 percent by weight,
- s is from about 3 percent to about 18 percent by weight,
- t is up to about 1 percent by weight, and
- u is from about 6 percent to about 20 percent by weight of the tetrapolymer,
- wherein the total of r, s, t and u is equal to about 100 percent;
- and combinations thereof.
A method for fabricating a photogenerating layer of a photoreceptor comprising:
- contacting a photogenerating component, a low boiling point solvent, at least one high boiling point solvent, and a resin selected from the group consisting of terpolymers of the formula:
- wherein x is from about 80 percent to about 87 percent by weight,
- y is from about 12 percent to about 18 percent by weight, and
- z is up to about 2 percent by weight of the terpolymer,
- wherein the total of x, y and z is equal to about 100 percent;
- and
- tetrapolymers of the formula:

- s is from about 3 percent to about 18 percent by weight,
- t is up to about 1 percent by weight, and
- u is from about 6 percent to about 20 percent by weight of the tetrapolymer,
- wherein the total of r, s, t and u is equal to about 100 percent,
- and combinations thereof to form a dispersion;
- and
- applying the dispersion to a substrate.
A photoreceptor comprising a photogenerating layer of about 15 weight percent to about 95 weight percent of a resin selected from the group consisting of terpolymers of the formula:
- wherein x is from about 80 percent to about 87 percent by weight,
- y is from about 12 percent to about 18 percent by weight,
- z is up to about 2 percent by weight of the terpolymer,
- wherein the total of x, y and z is equal to about 100 percent;
- and
- tetrapolymers of the formula:
- wherein R is an alkyl group containing from about 2 to about 12 carbon atoms,
- r is from about 80 percent to about 90 percent by weight,
- s is from about 3 percent to about 18 percent by weight,
- t is up to about 1 percent by weight, and
- u is from about 6 percent to about 20 percent by weight of the tetrapolymer,
- wherein the total of r, s, t and u is equal to about 100 percent,
- and combinations thereof;
- about 5 weight percent to about 85 weight percent of a photogenerating component;
- and a low boiling point solvent having a boiling point from about 35° C. to about 100° C. in combination with a high boiling point solvent having a boiling point from about 100° C. to about 160° C.
A photoreceptor comprising aphotogenerating layer of a photogenerating component, a low boiling point solvent, at least one high boiling point solvent, and a resin comprising tetrapolymers of the formula:
- wherein R is an alkyl group containing from about 2 to about 12 carbon atoms,
- r is from about 80 percent to about 90 percent by weight,
- s is from about 3 percent to about 18 percent by weight,
- t is up to about 1 percent by weight, and
- u is from about 6 percent to about 20 percent by weight of the tetrapolymer,
