is brought about by incorporation of polymers such as hydroxypropyl cellulose (HPC) or poly(ethyleneoxide) (PEO) in a host matrix of AlO(OH) or SiO2 along with an abrasion resistant binder such as polyvinyl alcohol (PVA). Water resistance and color fixation is brought about by inclusion of charge fixation agents, so called mordants, similar to that used in textile industry, eg., polyethylenimines.
