Disclosed herein are methods of making an adhesive composition, the methods comprising providing a polyurethane acrylate and combining with a vinyl ether and co-curing the combination to form an adhesive composition, wherein after curing the adhesive composition has a modulus at −20° C. of less than about 10.0 mPa and a creep recovery of greater than about 50%. Also disclosed are the resulting adhesive compositions.

A graft polyurethane copolymer dispersion can include dispersed polyurethane particles including a graft polyurethane copolymer. The graft polyurethane copolymer in this example includes a polyurethane backbone, a graft side-chain polymer attached to the polyurethane backbone, sulfonic acid groups, and isocyanate-generated amines. The graft side-chain polymer can include a poly(meth)acrylic moieties with C1 to C12 alkyl pendant groups, polyalkylene oxide pendant groups, or a combination thereof.

A formaldehyde free adhesive composition and a plywood obtained from the adhesive composition is provided, and the plywood has a balanced performance, such as high adhesion strength, sufficient pot-life, and good workability.

A hot melt adhesive (HMA), which is solid at room temperature, comprises the reaction product of 5 to 25% by weight of an isocyanate component having an NCO content of from about 20 to about 50% by weight, 75 to 85% by weight of a polyester, and 1 to 10% by weight of a hydroxy-polymer having an OH number of from about 40 to about 50. A method of forming the adhesive comprises the step of combining the isocyanate component, polyester, and hydroxy-polymer to form the adhesive. The adhesive can be used for various purposes, such as for forming an adhesive layer which adhesively couples surfaces together.

An alternative polyurethane composition is provided which comprises a reaction product of an azidated polyol and a poly(alkynyl carbamate) prepolymer reacted at a temperature of from 20° C. to 120° C., wherein the poly(alkynyl carbamate) prepolymer comprises a reaction product of a polyisocyanate and a stoichiometric equivalent of an alkynol of the formula (I),
HC≡C—R.sup.1R.sup.2—OH  (I),
and wherein R.sup.1 is an electron-withdrawing group selected from the group consisting of carbonyl, ester, amide, and urethane and R.sup.2 is a linear or branched alkyl chain having from 1 to 15 carbon atoms. The inventive alternative polyurethane composition position may be used to provide adhesives, sealants, films, elastomers, castings, foams, and composites.

A formaldehyde free adhesive composition and a plywood obtained from the adhesive composition is provided, and the plywood has a balanced performance, such as high adhesion strength, sufficient pot-life, and good workability.

The present application relates to an adhesive composition, an adhesive film, an adhesive optical filter and a display device.

Inkjet inks are described herein. In an example, an inkjet ink can comprise: at least one colorant; at least one solvent comprising glycerol in an amount of from about 1 wt % to about 20 wt % based on the total weight of the inkjet ink; water; and at least one binder, wherein the binder comprises a polyurethane-based binder dispersion.

Yellow inkjet inks are disclosed. In an example, an inkjet ink composition comprises: at least one colorant comprising at least one yellow pigment; at least one solvent comprising at least one triol; water; and at least one binder. The binder comprises a polyurethane-based binder dispersion, which comprises water and a polyurethane. The polyurethane comprises: (A) a polyisocyanate, (B) a first polyol having a chain with two hydroxyl functional groups at one end of the chain and no hydroxyl groups at an opposed end of the chain, (C) a second polyol having a chain with two hydroxyl functional groups at both ends of the chain, (D) a carboxylic acid functional group with two hydroxyl functional groups, and (E) a sulfonate or sulfonic acid functional group having two amino functional groups.

An alternative polyurethane composition is provided which comprises a reaction product of an azidated polyol and a poly(alkynyl carbamate) prepolymer reacted at a temperature of from 20° C. to 120° C., wherein the poly(alkynyl carbamate) prepolymer comprises a reaction product of a polyisocyanate and a stoichiometric equivalent of an alkynol of the formula (I),

HC≡C—R.sup.1R.sup.2—OH  (I),

and wherein R.sup.1 is an electron-withdrawing group selected from the group consisting of carbonyl, ester, amide, and urethane and R.sup.2 is a linear or branched alkyl chain having from 1 to 15 carbon atoms. The inventive alternative polyurethane composition position may be used to provide adhesives, sealants, films, elastomers, castings, foams, and composites.
