Antistatic coating on hydrophobic resin or paper support
First Claim
1. A sheet or web material comprising a hydrophobic resin support or paper support coated with at least one hydrophobic resin layer wherein said resin support or resin layer is coated with an outermost antistatic layer containing as an essential component a polythiophene with conjugated polymer backbone in the presence of a polymeric polyanion compound, wherein said antistatic layer contains also a hydrophobic organic polymer having a glass transition value (Tg) of at least 40°
- C., said polythiophene being present at a coverage of at least 0.001 g/m.sup.2 and the weight ratio of said polythiophene to said hydrophobic organic polymer being in the range of 1/10 to 1/1000.

Abstract
A sheet or web material comprising a hydrophobic resin support or paper support coated with at least one hydrophobic resin layer which is coated with an outermost antistatic layer which contains as an essential antistatic component a polythiophene with conjugated polymer backbone in the presence of a polymeric polyanion compound, wherein the layer also contains a dispersion of a hydrophobic polymer which polymer has a glass transition temperature (Tg) of at least 40° C. and the layer is a coherent layer.
