ABSTRACT:
A process for providing a low haze, high transparent, high heat-resistant laminate by forming a preform laminate of a high heat-resistant layer covered on both surfaces by a non-glass protective layer with at least one said layer being an as-cast acrylic layer. This combination can be readily stored for long periods of time or used immediately after the formation thereof by peeling off one of the as-cast acrylic layers and applying a transparent flexible adhesive layer thereto. The transparent material can be added to the adhesive layer. Many other combinations and laminates can be formed from the preform high heat-resistant laminate since during the preparation thereof, haze is not introduced to the transparency via moisture, and contact with haze-forming release coatings is avoided.
