The present invention provides compositions comprising the reaction product of an aliphatic diisocyanate, and a reactive intermediate made from one selected from the group consisting of oxazolidinones, benzoic sulfimides (saccharins), 1H-indole-2,3-diones (isatins), succinamides, N-hydroxysuccinamides, 4-hydroxy-3-methoxybenzaldehydes (vanillins), α-ketoamides, piperazines, benzofuranones, 3,4-dihydroxycyclobut-3-ene-1,2-diones (squaric acids), squaric acid esters, α-ketoamides, anilines, and α-ketoamide, phenols. The aliphatic diisocyanate comprises one selected from the group consisting of isocyanurates, biurets, iminooxadiazine diones, urethanes, uretdiones, carbodiimides, and allophanates. The resulting compositions may be useful in producing coatings, adhesives, sealants, castings, composites and films having durability, color stability, high gloss, and chemical resistance properties similar to those made from polyurethane.

Disclosed is an adhesive for laminated sheets comprising a urethane resin obtained by blending: (A) an acrylic polyol; (B) at least one component selected from carboxylic acids and carboxylic anhydrides; and (C) an isocyanate compound. The acrylic polyol (A) is obtained by polymerization of a polymerizable monomer, has a glass transition temperature of from −35° C. to 20° C., and has a hydroxyl value of from 0.5 to 40 mgKOH/g. The adhesive for laminated sheets is excellent in initial adhesion to a film, peel strength after aging and hydrolysis resistance for a long time under high temperature when a laminated sheet is produced, and wherein the adhesive does not impart an adverse effect to the appearance of the laminated sheet and the lamination process of films while improving the curability. The laminated sheet is suitably prepared using the adhesive for laminated sheets. An article comprising the laminated sheet can be prepared using the laminated sheet.

A surface protecting resin member includes a cured product of a composition containing an acrylic resin having a hydroxyl value within the range of 40 mgKOH/g to 280 mgKOH/g, a polyol having a hydroxyl value within the range of 40 mgKOH/g to 300 mgKOH/g, a multifunctional isocyanate, and a fluorotelomer alcohol represented by the following general formula CF.sub.3(CF.sub.2).sub.n—(CH.sub.2).sub.m—OH, where n is an integer of 1 or more and m is an integer within the range of 1 to 4.

Provided are a method of preparing a polyurethane prepolymer with high functionality and the polyurethane prepolymer with high functionality prepared therefrom and a curing agent comprising the same. The method includes the steps of: Step (A): providing an alcohol composition comprising a first polyol having 2 or 3 OH groups and a second polyol having 4 or more OH groups; Step (B): reacting the alcohol composition with a polyisocyanate to undergo a first polymerization, so as to obtain an intermediate; wherein a molar ratio of a total number of the OH groups of the alcohol composition to a total number of NCO groups of the polyisocyanate is from 1:2 to 1:6; and Step (C): adding a catalyst to carry out a second polymerization of the intermediate to obtain the polyurethane prepolymer with high functionality, which has four or more NCO groups.

The present invention provides an electron beam curable coating composition comprising: an electron beam curable component (A) which contains 10% by mass or more of a multifunctional (meth)acrylate; and a room temperature curable component (B) which contains 1 to 15% by mass of an isocyanate group and is not cured by electron beam irradiation, wherein a solid content mass ratio of the component (B) to a total amount of the components (A) and (B) is 20 to 55% by mass.

Printable compositions comprising a liquid carrier; and a radiation curable polyurethane dispersed in the liquid carrier are described, as well as methods of preparing the printable compositions and methods of printing using the printable compositions.
