Claim Text:
1. An adhesive composition for bonding wood, comprising: (a) 1 to 50% by weight of a vinyl acetate-ethylene copolymer-based emulsion, wherein the copolymer comprises, based on the total weight of the copolymer: wherein the copolymer-based emulsion is formed by emulsion polymerization of the monomers in the presence of 0 to 3% by weight of an at least partially water-soluble polymeric protective colloid and 1 to 5% by weight of a surfactant, both based on the total weight of the monomers, wherein a combination of a higher amount of surfactant and a lower amount of polymeric protective colloid is used; and (b) 15 to 1% by weight of a vinyl alcohol polymer which has a degree of alcoholysis of at least 87.5 mole %; (c) 25 to 5% by weight of a polyisocyanate; and (d) up to 40% by weight of one or more fillers, wherein the weight % of components (a)-(d) are all based on the total weight of the composition.
