Abstract
There are disclosed radiation curable compositions containing (a) about 5-95% by weight of at least one cyanoalkoxyalkyl or cyanothiaalkylalkyl acrylate, (b) about 1-90% by weight of a photopolymerizable acrylated polymer or oil, and (c) from 0 to about 5% by weight of a photoinitiator. The compositions are useful as 100% solids coatings and adhesives compositions which are curable upon exposure to radiation, and which are useful in a variety of applications such as for coating textiles and fabrics, for producing pressure sensitive adhesives, and for producing laminating adhesives.
Claims7
A radiation curable composition comprising
- (a) about 5-95% by weight, based on total composition, of at least one cyanoethoxyalkyl acrylate having the formula
- H.sub.2 C.dbd.CH-C(O)-O-R-X-CH(R.sup.1)-CH(R.sup.2)-CN
- wherein R is a (C.sub.2 -C.sub.5)alkylene group or a (C.sub.2 -C.sub.5)oxaalkylene or thiaalkylene group having discrete alkylene segments containing at least two carbon atoms joined by O or S atom;
- R.sup.1 and R.sup.2 independently, are a straight-chain or branched-chain (C.sub.2 -C.sub.5)alkyl group;
- and X is O or S;
- (b) about 1-90% by weight, based on total composition, of at least one radiation curable component selected from the group consisting of acrylated epoxidized drying-type oils, acrylic oligomers, acrylated bisphenol A/epoxy resins, acrylated urethane prepolymers, and unsaturated polyester resins;
- and
- (c) from 0 up to about 5% by weight, based on total composition, of a photoinitiator.
