Abstract
The invention relates to a recording material for the production of offset printing plates, having a web- or plate-form support, a radiation-sensitive layer on the front of the support and a continuous, pigment particle-free layer on the back of the support. The back layer essentially consists of an organic polymeric material having a glass transition temperature Tg of at least 45° C., and its surface has a Bekk smoothness of from 5 to 800 s. It also relates to a process for the production of this recording material.
