Abstract
Radiocurable compositions of matter consisting essentially of Diels-Alder reaction products between (A) at least one dienophile containing at least two double bonds >C=C<, at least one of which derives from acrylic acid and (B) at least one linear or cyclic diene containing at least two conjugated olefinic double bonds, the preparation thereof and sealers, adhesives, paints, varnishes and inks formulated therewith.
Claims19
A radiation-curable composition which comprises a Diels-Alder reaction product between at least one dienophile (A) having the formula ##STR9## wherein Z is hydrogen or COOH, Y is the radical of a polyhydric compound having a molecular weight lower than 3000 containing 2 to 6 hydroxyl groups, n is 1 to 5, and x is 0 to 4, and at least one diene (B) group consisting of a glyceride of an unsaturated fatty acid containing conjugated double bonds.
The process of claim 31, wherein the reaction is carried out in the absence of solvents when the dienophile (A) and the diene (B) form a liquid mixture at ambient temperature.
Varnishes, paints or inks curable by bombardment with accelerated electrons comprising the radiation-curable composition of claim 24.
