Abstract
Duplicate thermoplastic plates are composed of a composition comprising a 1,2-polybutadiene having a crystallinity of about 10-30% and an intrinsic viscosity of greater than about 0.7. Matrices against which the duplicate thermoplastic plates are molded are formed of material containing said 1,2-PBD and a photoinitiator or a thermo-curable catalyst. The duplicate thermoplastic plates and matrices can give a high duration and reproducibility from an original pattern bearing design or image in relief, and they are molded with ease and in a great amount without difficulty. The use of the thermoplastic plates or matrices can provide a good releasability from the matrix against which the said plates are molded and from the original pattern against which the matrices are formed.
