Laminate comprising a carrier and a coating layer, wherein the coating layer is applied over at least part of the carrier, the coating layer comprising a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid, the coating layer having a thickness in the range of 10-4000 microns, wherein the aliphatic polyalcohol contains at least 50 mol. % of glycerol and the polyacid contains at least 30 wt. % of tricarboxylic acid. Optionally a second carrier may be applied over at least part of the coating layer. If so desired, a further coating layer is applied over at least part of the second carrier, with optional further carrier-coating stacks applied over the further carrier. Preferably the tricarboxylic acid is citric acid. The laminate according to the invention may be, e.g., a multiplex-type material. The laminate according to the invention has fire-retardant properties which makes it particularly suitable for use in applications where fire-retardancy is an issue. |
