Abstract
The present invention is directed to a multilayer article comprising a substantially water-resistant, coated, microporous substrate connected to a substantially nonporous material. Further, the present invention is directed to a process for producing the multilayer article. The multilayer article and method of the present invention is especially useful for an ink jet recordable substrate and printing on said substrate.
Claims39
A multilayer article comprising a microporous substrate at least partially connected to a substantially nonporous material, said microporous substrate at least partially coated with a substantially water-resistant coating composition, said coating composition comprising a stable dispersion of:
- (a) an aqueous polyurethane dispersion;
- and
- (b) a cationic nitrogen-containing polymeric dye fixative material at least partially dissolved in an aqueous medium.
A method for producing a multilayer article comprising the steps of:
- (a) providing a microporous substrate having a top surface and a bottom surface;
- (b) providing a substantially water-resistant coating composition comprising a stable dispersion of:
- a. an aqueous polyurethane dispersion;
- and
- b. a cationic nitrogen-containing polymeric dye fixative material at least partially dissolved in an aqueous medium;
- (c) at least partially applying said coating composition to at least one surface of said microporous substrate;
- (d) at least partially connecting said microporous substrate of (c) to a substantially nonporous material.
A multilayer article comprising a microporous substrate at least partially connected to a substantially nonporous material, said microporous substrate at least partially coated with a substantially water-resistant coating composition, and at least one of said microporous substrate and substantially nonporous material at least partially coated with a friction-reducing coating composition.
