Abstract: Provided is a laminate label adapted for use on plastic containers suitable for containing a pharmaceutical or food grade product. The laminate label includes a substantially clear or translucent protective polymeric layer bound to a face stock by a radiation-cured adhesive composition formulated from a low-migration, radiation-curable adhesive composition containing at least 50% of one or more radiation-curable, carboxylic acid functional monomers.

Abstract: Optical fiber coatings are disclosed having excellent ribbon stripping and adhesion behavior. The coatings are radiation-curable. The excellent stripping and adhesion behavior can be achieved by several means which include by use of additives, by use of radiation-curable oligomers having higher molecular weight, or by use of coatings having certain thermal properties. Combination of means can be employed. Stripping behavior can be measured by crack propagation and fiber friction measurements.

Abstract: Radiation-curable compositions, having high elongation at break and toughness after cure can include the following pre-mixture components: a) a polymer, oligomer or monomer having at least one (meth)acrylate functional group; b) an oligomer or monomer, exclusive of (meth)acrylate functional groups, having an ethylenically unsaturated functional group; and c) an elongation promoter; wherein the composition, after radiation-cure, has an elongation at break of at least about 200%. Glass substrates and optical fibers are coated with the radiation-curable composition. Monofilament fiber or a plurality of fiber filaments, such as sewing thread, are coated with the radiation-curable binder composition, which after cure, demonstrates high elongation at break.

Abstract: There are described vinyl ether terminated ester oligomers which cure or polymerize particularly rapidly, especially by cationic polymerization which is radiation induced in the presence of an onium salt. The oligomeric units arise from the reaction of a polycarboxylic acid having at least three carboxylic acid groups with a diol, although esters with triols and higher polyhydric diols also are useful, especially where an extensively cross-linked product is desired. The carboxyl-terminated oligomeric esters are esterfied with vinyl ether terminated alcohols which can be thought of as the adducts of alkynes and diols.

Abstract: There are described vinyl ether terminated ester and urethane oligomers which cure or polymerize particularly rapidly, especially by cationic polymerization which is radiation induced in the presence of an onium salt. The oligomeric units arise most often from the reaction of a dicarboxylic acid or diisocyanate with a diol. The carboxyl-terminated oligomeric esters are esterified with vinyl ether terminated alcohols which can be thought of as the adducts of alkynes and diols which are bis(hydroxyalkyl)cycloalkanes where the cycloalkane is of ring size 5 through 8.

Abstract: Vinyl ether terminated urethane resins may be prepared by reacting the product obtained by the addition of acetylene to an organic polyol with an isocyanate-containing compound at temperatures ranging from about ambient to about 125.degree. C. The thus prepared resin may then be cured by irradiation from an electron beam, thermally or by exposure to an ultraviolet light to cure the resin and form a coating material.
