Abstract
A phase separated composition suitable for coating onto an ink-jet recording sheet comprising, a) at least one nonionic fluorocarbon surfactant having a hydrophilic portion and a hydrophobic portion, b) at least one polymer selected from the group consisting of hydroxycellulose and substituted hydroxycellulose polymers, and c) at least one phase separation additive such composition being crosslinkable when subjected to temperatures of at least about 90.degree. C., such composition forming a microporous coating.
Claims9
An ink-jet recording sheet comprising a film substrate bearing on at least one major surface thereon a two-layer imageable coating system wherein at least one of said layers is microporous, comprising:
- a) an absorptive bottom layer comprising at least one crosslinkable polymeric component and at least one water-absorbing hydrophilic polymeric material, and
- b) an optically clear top layer comprising at least one nonionic fluorocarbon surfactant having a hydrophilic portion and a hydrophobic portion, and at least one polymer selected from the group consisting of hydroxycellulose and substituted hydroxycellulose polymers, said top layer having been crosslinked on said film substrate by application of heat.
