ABSTRACT:
A liquid ink composition containing organosols having side-chain or main-chain crystallizable polymeric moieties is described. The incorporation of organosols having crystallizable polymeric moieties into the ink compositions provide improved blocking resistance and improved erasure resistance when used in ink transfer, ionographic, electrographic and electrophotographic color printing or proofing processes.
