Abstract
A thermal transfer sheet suitable for preparing a lighographic printing form cylinder is provided including a substrate layer and a donor layer. The substrate layer includes a first polymer having mechanical stability at temperatures greater than 150 degrees C. and light transmission of at least 70% for wavelengths of from about 700 nm to about 1600 nm. The donor layer includes a second polymer having acidic groups and/or optionally substituted amide groups and an additive is capable of converting incident laser light energy into heat energy. A wetting aid and/or a solvent are also included in the donor layer. A method of making the thermal transfer sheet is also provided.
