Abstract
The present invention provides improved electrostatic charge dissipating hard laminates by addition of a conductance-modifying component selected from inherently conductive polymers, conductive nanophase materials, or mixtures thereof, to a cellulose-based substrate and thermosetting polymer resin.
Claims20
An electrostatic dissipating laminate structure comprising:
- (a) a cellulose-based substrate;
- (b) a conductance-modifying component selected from the group consisting of an inherently conductive polymer, a conductive nanophase material and mixtures thereof;
- and
- (c) a thermosetting polymer resin.
An improved method of forming an electrostatic dissipating hard laminate structure wherein a cellulose-based structure is impregnated with a thermosetting polymer resin, said improvement comprising imparting electrostatic dissipating properties to said laminate structure wherein the improvement comprises adding a conductance modifying component selected from the group consisting of an inherently conductive polymer, a conductive nanophase material and mixtures thereof to said laminate structure by (i) impregnating said polymer resin with said conductance modifying component;
- or (ii) forming an aqueous dispersion of said conductance modifying component and applying said aqueous dispersion to said hard laminate structure. 21. An improved method as defined in claim 20 wherein said application of said aqueous dispersion to said hard laminate structure comprises aerosol spraying. 22. An improved method as defined in claim 20 wherein said application of said aqueous dispersion to said hard laminate structure comprises applying said aqueous dispersion to a transfer coating and then applying said transfer coating to said hard laminate structure.
