METHOD FOR CATIONIC CONVERSION OF NANO-MILLED CALCIUM CARBONATE

摘要

A method of forming a print medium includes coating (240) at least one side of a base substrate (110) with anionically-charged nano-milled calcium carbonate that has been mixed (220) with a cationic conversion agent (280) to convert said coating (120) to a cationically-charged coating, wherein a primary size of particles of said nano-milled calcium carbonate is 10-20 nm or smaller.
