Abstract
A transferable film composition coated on a temporary support is used in the manufacture of heat and pressure consolidated laminates to produce laminates of improved surface strength and functional properties. The film is composed of polyvinyl butyral resin and melamine resin which reacts with a resin in the laminates. Additives may be included in the film composition for functional purposes and appearance.
Claims3
In a process for preparing a decorative laminate comprising the steps of:
- (A) stacking together in an assembly
- (a) one or more resin impregnated core sheets,
- (b) a decorative fibrous sheet impregnated with a noble thermosetting resin, and
- (c) a releasing carrier surface coated with a film composition in contact with the decorative fibrous sheet;
- (B) applying heat and pressure to consolidate the assembly into a unitary structure;
- and
- (C) separating the releasing carrier surface from the unitary structure;
- the improvement wherein said film composition comprises polyvinyl butyral resin and melamine resin which reacts with the noble thermosetting resin of the decorative fibrous sheet during assembly consolidation.
