Abstract
An industrial roll includes: a substantially cylindrical core and a cover overlying the adhesive layer. The cover typically comprises a polymeric top stock layer which comprises a mixture of a polymeric material and at least one of a piezochromic material and a thermochromic material. In this configuration, the pressure and/or temperature experienced by the roll cover at any location thereon can be determined visually, without the need for external equipment.
