Radiation curable compositions comprising at least one radiation curable oligomer responding to a structure (C)&#x2014;(B)-(A)-[(B)(C)]wherein (A) is the residue of one or more hydroxyl functional polyester having a molecular weight Mhigher than 900, a Tand/or Tm of 5 less than 30&#xb0; C., and which is obtained from an acid constituent comprising at least 75 mole % of saturated aliphatic polyacid and, optionally, 0 to 25 mole % of another polyacid and an alcohol constituent, (B) is the residue of one or more polyisocyanate, (C) is the residue of one or more ethylenically unsaturated hydroxyl compound, and x is from 0.5 to 10.

Radiation curable compositions

Radiation curable compositions comprising at least one radiation curable oligomer obtained from the reaction of one or more carboxyl functional polyester (a) having a glass transition temperature Tand/or melting temperature Tof less than 30&#xb0; C., with (b1) one or more (meth)acrylated mono-epoxide, and/or (b2) one or more polyepoxide and one or more &#x3b1;, &#x3b2; unsaturated carboxylic acid.

The invention relates to a process for preparing a coated metal sheet coil comprising the coating of the metal sheet with a curable composition comprising an (meth)acrylated oligomer which is the reaction product of a carboxyl functionalized polybutadiene comprising x equivalents of &#x2014;COOH groups with (i) y equivalents of one or more (meth)acrylated monoepoxides or (ii) a mixture of z equivalents of one or more polyepoxides and at least (z&#x2212;x) equivalents of an &#x3b1;,&#x3b2;-unsaturated carboxylic acid; with z&#x3e;x and y&#x2267;x.

Process for applying a coating to a coiled metal sheet

The invention relates to a process for preparing a coated metal sheet coil comprising the coating of the metal sheet with a curable composition comprising an (meth)acrylated oligomer which is the reaction product of a carboxyl functionalized polybutadiene comprising x equivalents of &#x2014;COOH groups with (i) y equivalents of one or more (meth)acrylated monoepoxides or (ii) a mixture of z equivalents of one or more polyepoxides and at least (z-x) equivalents of an &#x3b1;,&#x3b2;-unsaturated carboxylic acid; with z&#x3e;x and y&#x2267;x.

Process for applying a coating to coiled metal sheet

The present invention relates to radiation-curable compositions useful as ink vehicles or inks, in particular UV-curable inks, such as UV-litho inks, comprising a (meth)acrylated styrene allyl alcohol copolymer obtained from the (meth)acrylation of a styrene allyl alcohol (SAA) copolymer with (meth)acrylic acid and/or one or more alkyl(meth)acrylates, and at least one alkoxylated acrylated monomer.
