Cockle resistant inkjet paper |
(57) A minor but effective amount of a high surface area pigment having an affinity for
water and a large internal pore volume is mixed with the filler pigments normally
used in the paper basestock for inkjet recording sheets so as to absorb excess water
from the inks during printing and provide cockle resistance to the sheets.
