Drive belt having a belt rear side which is provided for driving auxiliary units, in particular V-ribbed belt, wherein the belt rear side is profiled and is preferably provided with an embossed profile, wherein the profile of the rear-side surface of the drive belt has a multiplicity of projections in the shape of truncated pyramids, the height h of which is less than 1 mm, and is preferably in macroscopic orders of magnitude where h&#x2264;0.2 mm, wherein the base areas Aof the projections in the shape of truncated pyramids have an area of &#x2264;1.0 mmand the top surfaces Ahave an area of &#x2264;0.8 mm.

Drive belt having a profiled belt rear side

A power transmission belt () having an elastic main body () includes a top layer as the belt backing and a bottom section having a power transmission zone. The power transmission zone and/or the top layer has/have a coating (), characterized in that the coating () of the power transmission zone and/or the top layer includes at least the following layer construction: a base coating () made of a textile material, wherein the base coating () forms a bond with the elastic main body () and has a surface coating () including at least a mixture A, which contains at least one reactive diluent as per DIN 55945:2007-03. The invention further relates to a method for producing such a power transmission belt. The novel coating concept is applicable in particular in a toothed belt.
