Abstract
Improved thermal and mechanical barrier layers coated on the recording layer of an optical recording element are disclosed. The improved layers comprise water-soluble polymers having a glass transition temperature when dry of at least 100.degree. C. and preferably at least 150.degree. C. These barrier layers are easily coated and do not significantly degrade the performance of the element. Optional layers such as spacer layers and topcoat layers coated on the barrier layers are also disclosed.
