Abstract
An ink jet recording element comprising a support having thereon a porous image-receiving layer comprising at least about 50% by weight of particles and less than about 20% by weight of a binder, the particles comprising a mixture of (a) inorganic particles having a primary particle size of from about 7 to about 40 nm in diameter which may be aggregated to provide a mean aggregate particle size of up to about 500 nm; and (b) colloidal particles having a mean particle size of from about 20 to about 500 nm; and wherein the difference between the mean aggregate particle size of the (a) inorganic particles and the mean particle size of the (b) colloidal particles is within about 10%.
Claims18
An ink jet recording element comprising a support having thereon a porous image-receiving layer comprising at least about 50% by weight of particles and less than about 20% by weight of a binder, said particles comprising a mixture of
- (a) inorganic particles having a primary particle size of from about 7 to about 40 nm in diameter which may be aggregated to provide a mean aggregate particle size of up to about 500 nm;
- and
- (b) colloidal particles having a mean particle size of from about 20 to about 500 nm;
- and wherein the difference between said mean aggregate particle size of said inorganic particles and said mean particle size of said colloidal particles is within about 10%.
