ABSTRACT:
A heat-curable multilayer composite sheet comprising a layer comprising one or more unsaturated compounds which are normally solid or liquid free radical reactive unsaturated compounds and a layer comprising a normally solid or liquid free radical initiator, the layers being bonded to each other as a laminate as separate layers at a temperature at which the free radical initiator does not lose its free radical reaction-initiating capability, and,
a process for preparing a heat-curable multilayer composite sheet, which comprises coating a layer-forming material containing a normally solid or liquid free radical reactive unsaturated compound on a strippable sheet to form an unsaturated compound material layer on the strippable sheet, coating a layer-forming material containing a normally solid or liquid free radical initiator on a strippable sheet to form a free initiator layer on the strippable sheet, bringing the unsaturated compound material layer into contact with the free radical initiator layer, and bonding them to each other at a temperature at which the free radical initiator layer does not lose its free radical reaction initiating ability.
