Author: Fischer, Kurt ; Phau, Awie

The waterproofing of paper by the use of rosin sizes, paraffins, and synthetic sizes is discussed.Topics included are: (1) sizing processes; (2) sizing agent compositions, (3) sizing agents on a natural rosin basis; (4) rosin soaps; (5) rosin size dispersions; (6) synthetic sizes; (7) synthetic sizes based on alkyl ketene dimer (AKD); (8) synthetic sizes based on alkenyl succinic anhydride (ASA); (9) other monomer size compositions; (10) polymers used as size compositions; (11) surface sizes; (12) combination sizing; and (13) size testing.

Surface sizing of ink-jet papers

Author: Fischer, Kurt

A review with 5 referencesThe requirements on ink-jet papers are summarized in view of possible misprints.Mottling, line broadening, wicking, feathering, and bleeding of the inks are considered.Usually, polymeric sizing agents (styrene/maleinic acid anhydride copolymer, styrene/acrylate copolymer, and polyurethanes) are used to improve the printability of the ink-jet papers.Application examples are given showing the effectiveness of the different sizing agents on different printing machines.
