Abstract
A non-crosslinked composition suitable for coating onto an ink-jet recording sheet comprising. a) at least one nonionic fluorocarbon surfactant, b) at least one alkanolamine metal chelate wherein said metal is selected from the group consisting of titanium, zirconium and aluminum, and c) at least one polymer selected from the group consisting of hydroxycellulose and substituted hydroxycellulose polymers, such composition being crosslinkable when subjected to temperatures of at least about 90.degree. C.
Claims9
An ink-jet recording sheet comprising a substrate having coated on at least one surface thereof a two-layer coating comprising:
- a) an absorptive bottom layer comprising
- i) at least one crosslinkable polymeric component;
- ii) at least one liquid-absorbent component comprising a water-absorbent polymer, and
- iii) from 0 to about 5% of a crosslinking agent,
- b) an optically clear top layer comprising
- i) from about 0.05% to about 6% of at least one nonionic fluorocarbon surfactant,
- ii) from about 5% to about 94% of a hydroxycellulose or substituted hydroxycellulose polymer, and
- iii) a metal chelate selected from the group consisting of alkanolamine titanium chelates, alkanol zirconium chelates, and alkanolamine aluminum chelates.
