A polyurethane adhesive composition prepared by incorporating phosphorus oxy acid or a derivative thereof, an amine compound and an epoxy resin into an organic polyisocyanate and an organic polyol. The polyurethane adhesive composition is employed in the manufacture of composite films by lamination of various plastic films, metal foils and so forth. The composition is excellent in adhesive properties, acid resistance and hot water resistance.

Polyurethane adhesive compositions

A polyurethane adhesive composition containing an oxy acid of phosphorus or a derivative thereof, a carboxylic acid or an anhydride thereof, a silane coupling agent and an epoxy resin can serve as an adhesive for manufacturing food packaging materials, for instance, giving bonds having very good bond strength, heat resistance and hot water resistance between a metal foil and a plastic film.

Polyurethane adhesive of epoxy resin, polyisocyanate, phosphorus oxy

A polyurethane adhesive composition containing an oxy acid of phosphorus or a derivative thereof, a carboxylic acid or an anhydride thereof and an epoxy resin can serve as an adhesive for manufacturing food packaging materials, for instance, giving bonds having very good bond strength, heat resistance and hot water resistance between a metal foil and a plastic film.

A heat adherable resin composition which comprises (a) a carboxyl-modified resin obtained by the reaction of a partially saponified product of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 10 to 55 weight percent with an unsaturated carboxylic acid or dicarboxylic acid anhydride and (b) a monoolefin-unsaturated carboxylic acid copolymer or metal salt thereof is valuable as an adhesive layer for the heat sealable sheet made of aluminum foil which is used in the food industry in sealing and packaging the mouths of glass containers.

Heat adherable resin compositions and aluminum sheet laminated with the

Disclosed are a colorless and transparent carboxyl-modified resin of saponified ethylene-vinyl acetate copolymers prepared from an ethylene-vinyl acetate copolymer, the 1.0 mm-thick sheet therefrom having a total transmittance of more than 90%, a haze of less than 3% and a yellowness index of 3 and the preparation of the resin. The uses of the resin are also disclosed for laminated glass wherein the resin is used as an interlayer as well as for a solar cell module wherein the resin is used as a sealing material of a semiconductor element.

Resin from saponified ethylene-vinyl acetate copolymers, production and

A powdered composition comprising (1) an organic polyisocyanate blocked with ethyleneimine and (2) a partially hydrolyzed product of an ethylene-vinyl ester copolymer and/or a carboxyl-modified-product of said partially hydrolyzed product exhibits exceedingly good levelling and post-curing characteristics and is advantageously flame-sprayed to give a coating film having good weatherability, heat resistance and chemical resistance.
