Latest Patents

Dörr's latest patents include innovative technologies that enhance the performance and quality of recording materials. The first patent describes a radiation-sensitive recording material featuring a structured back. This invention relates to a recording material designed for the production of offset printing plates, which includes a web- or plate-form support, a radiation-sensitive layer on the front, and a continuous, pigment particle-free layer on the back. The back layer is primarily composed of an organic polymeric material with a glass transition temperature of at least 45°C, and it boasts a Bekk smoothness ranging from 5 to 800 seconds. Additionally, the patent outlines a process for producing this recording material.

The second patent focuses on a recording material that has a negative-working, radiation-sensitive layer. This layer includes additives that promote developability, such as a diazonium salt, a polymeric binder, and a sulphobetaine. The recording material features a dimensionally stable, two-dimensional support, preferably made of aluminum. The front of the material may be matted or pigmented, while the back is coated with an organic polymeric material. The inclusion of sulphobetaine enhances the solubility of diazonium salts in aqueous-alkaline developers without compromising the resistance of the offset printing plates produced from this material.
