Abstract
Abstract An ink jet recording sheet comprising a sheet support, e.g., paper, bearing a surface coating comprising (a) a water soluble organic polymeric binder, (b) a titanium chelate crosslinking agent as defined, and (c) an inorganic filler, the weight ratio of (c) to (a) preferably being about 7 to 1 to about 1 to 2. The ink jet recording sheet is useful for ink jet printing.

Claim 1
Independent Claim
168 words
An opaque ink jet recording sheet comprising a support and a surface coating on the support, the surface coating comprising (a) a water soluble polymeric binder, (b) a titanium chelate crosslinking agent having the general formula selected from the group consisting of: ##STR5## wherein X is a functional group containing oxygen or nitrogen; Y is alkylene of 1 to 6 carbon atoms or arylalkyl R is H, alkyl of 1 to 6 carbon atoms, or hydroxy substituted alkyl of 1 to 6 carbon atoms; and ##STR6## wherein R 1 , R 2 , or R 3 can be the same or different, and are alkylene of 1 to 4 carbon atoms, and R4 is alkyl of 1 to 6 carbon atoms; and (c) an inorganic filler, the binder being crosslinked to the crosslinking agent, the surface coating being applied in a weight range of from about 1 g/M 2 to about 10 g/M 2 and the weight ratio of (c) to (a) being about 7:1 to about 1:2.
