Abstract:
Described in preferred embodiments are UV curable coating compositions including a unique blend of aliphatic urethane acrylate resins. Also described are coated articles and methods for their production involving the use of the coating compositions.

Claim (Index 39):
A UV curable coating composition, comprising:\n (1) an inert solvent; (2) a first aliphatic urethane acrylate resin, which is a reaction product of a polyisocyanate component represented by formula I below with an alcohol component containing at least one monobasic, hydroxy-functional, linear or branched C 1 -C 12  alkyl ester of (meth)acrylic acid: wherein R 1 , R 2 , and R 3  of formula I are the same or different, and each comprise linear or branched, C 4 -C 20  (cyclo)alkyl groups, wherein X is the same or different and comprises isocyanate groups and wherein R 1 , R 2 , and R 3  of formula I are attached to a nitrogen atom;\n (3) a second aliphatic urethane acrylate resin comprising the structure of formula II: \n wherein A 1 , A 2 , and A 3  are each a group comprising the structure of formula III: wherein R 1 , R 2 , and R 3  of formula III are the same or different, and each comprise a linear aliphatic group having from 2 to 12 carbon atoms, or a cycloaliphatic group having from 4 to 12 carbon atoms, wherein the second urethane acrylate has an average molecular weight of 500 to 2,000, wherein the second urethane acrylate resin contains 6 polymerizable acrylate groups per molecule, and wherein the first aliphatic urethane acrylate resin and the second aliphatic urethane acrylate resin comprise a weight ratio of 1:3 to 3:1;\n (4) a first multifunctional acrylate, wherein the first multifunctional acrylate has an average molecular weight of 170 to 1,000, and wherein the first multifunctional acrylate comprises two polymerizable unsaturated groups per molecule; \n (5) a second multifunctional acrylate, wherein the second multifunctional acrylate is selected from at least one of pentaerythritol triacrylate and trimethylolpropane triacrylate; \n (6) a first photoinitiator and a second photoinitiator, wherein the first and second photoinitiators are selected from the group consisting of diphenylphosiphine oxides, pheylglyoxylates, \u03b1-hydoxyketones, difunctional \u03b1-hydoxyketones and combinations thereof; \n (7) a hindered amine light stabilizer; \n (8) a UV absorber comprising at least one of a benzotriazole and a benzotriazine; \n (9) an acrylated organic-inorganic hybrid material; \n (10) a phenolic based antioxidant; and \n (11) a flow additive.
