Anti-static coated venetian blind slat and method of preparation thereof

A method for treating a coil of a window blind slat substrate comprising the steps of:

• unwinding said substrate coil;
• and
• coating said substrate coil with an anti-static conductive coating, said conductive coating comprising a paint and sufficient inert, inorganic conductive filler to result in a surface resistivity for said substrate coil of at most approximately 8.9.times.10.sup.7 ohms per square, wherein a tendency of the resultant coated substrate coil to attract and accumulate airborne dust particles is reduced as compared to a comparable blind lacking said anti-static conductive coating.

An improved Venetian blind of the type including a headrail, a plurality of tiltable spaced horizontal slats having rout holes formed therein, a bottom rail and at least one draw cord coupled to the headrail and to the bottom rail and passing through the rout holes in the slats, wherein the improvement comprises:

• an anti-static conductive coating extending on each slat in the plurality of slats, said anti-static conductive coating comprising a paint and sufficient inert, inorganic conductive filler to result in a surface resistivity for the slats of at most approximately 8.9.times.10.sup.7 ohms per square, wherein a tendency of the slats to attract and accumulate airborne dust particles is reduced as compared to a comparable blind lacking said anti-static conductive coating.

A Venetian blind slat comprising a slat substrate having peripheral exterior surfaces;

• and an anti-static conductive coating on said substrate, said anti-static conductive coating comprising a paint and sufficient inert, conductive filler to result in a surface resistivity for said slat of at most approximately 8.9.times.10.sup.7 ohms per square to reduce the tendency of the resultant coated slat to attract and accumulate airborne dust particles when compared to a comparable blind lacking said anti-static conductive coating.
