ABSTRACT:
A phenolic resin based laminate material which can be cross-linked by acid catalysis, endowed with a reinforcement, comprising at least two surfaces and having on at least one of its two surfaces at least one additional nonphenolic resin-based layer is disclosed.
In accordance with the invention, the additional layer in contact with the phenolic resin is obtained from a formula comprising an unsaturated polyester resin, a cross-linking solvent of said resin, possibly one or several other additives, at least one of the main components having a formula comprising hydrophilic centers in a number at least equal to the number of non-saturation centers in the polymeric chain of the resin.
