Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
87 words
A process for preparing a photoreceptor comprising the steps of: a) dissolving an aromatic amine charge transporting material in a solvent consisting essentially of a polymerizable film forming monomer or a mixture of polymerizable film forming monomers to form a coating solution, said solvent subject to addition polymerization in the presence of a cationic initiator; b) coating a substrate with said coating solution; and c) photochemically curing said coating solution such that said monomer forms a polymer that is miscible with said aromatic amine charge transporting material.
Claim 2
Dependent Claim
