Abstract
A decorative pleatable material adapted for the fabrication of pleated shades is described. The material is comprised of a pleatable fabric having a decorative resin coat containing desired pigment adhered to the face of the fabric by means of a polyurethane layer embedded in the structure of the fabric. The decorative resin coat is overlaid with a top-coat that prevents blocking during pleating. A preferred top-coat is comprised of a film forming cellulose derivative containing amorphous fumed silica. A film transfer strip for producing the decorative pleatable material is also described.
Claims36
A pleatable material comprising:
- a. a pleatable fabric;
- b. a continuous uniform first polyurethane resin layer on the face of the fabric forming a barrier between the back and face of the fabric;
- c. a continuous uniform decorative coating overlying said first polyurethane resin comprised of a bottom layer, a top layer and at least one intermediate layer, said layers each comprised of a pigment-containing cross-linked first acrylic or second polyurethane polymer;
- and
- d. a continuous uniform top-coat overlying the top layer of said decorative coating comprised of (1) cross-linked resin selected from the group consisting of cross-linked polyester resin, second cross-linked acrylic resin, and third cross-linked polyurethane resin or (2) a film forming cellulose derivative, said cross-linked resins and cellulose derivative containing an anti-blocking agent comprising particulate silica, silicone polymer or a combination of particulate silica and silicone polymer;
- wherein the bottom layer of the decorative coating is cross-linked with the first polyurethane resin layer at the interface of said bottom and first urethane layers and each layer of said decorative coating is cross-linked with each overlying layer.
A pleatable fabric comprised of a pigment-containing resin coat adhered to a face of said fabric by means of a continuous uniform first polyurethane layer embedded in the structure of said fabric and forming a barrier between the back and face of said fabric, said pigment-containing resin coat being overlaid with a top-coat comprised of a cellulose derivative resin containing amorphous fumed silica.
A pleated fabric comprised of a pigment-containing resin coat adhered to a face of said fabric by means of a continuous uniform first polyurethane layer embedded in the structure of said fabric and forming a barrier between the back and face of said fabric, said pigment-containing resin coat being overlaid with a top-coat comprised of a cellulose derivative resin containing amorphous fumed silica.
A pleatable fabric comprised of a pigment-containing resin coat adhered to a face of said fabric by means of a continuous uniform first polyurethane layer embedded in the structure of said fabric and forming a barrier between the back and face of said fabric, said pigment-containing resin coat being overlaid with a top-coat comprised of a polyester resin cross-linked with a silicone resin.
A pleated fabric comprised of a pigment-containing resin coat adhered to a face of said fabric by means of a continuous uniform first polyurethane layer embedded in the structure of said fabric and forming a barrier between the back and face of said fabric, said pigment-containing resin coat being overlaid with a top-coat comprised of a polyester resin cross-linked with a silicone resin.
A film transfer strip comprising:
- a. a web with a release film thereon;
- b. a layer of film forming cellulose derivative containing particulate silica releasably supported on the release film on said web;
- c. a continuous uniform decorative coating overlying said layer of film forming cellulose derivative comprised of a bottom layer, a top layer and at least one intermediate layer, said layers each comprised of a pigment-containing acrylic polymer and thermosetting additive;
- and
- d. a continuous uniform first polyurethane resin layer overlying the top layer of the decorative coating.
