  • Dual cure systems
    Patent number: 7553906
    Abstract: An organic polyisocyanate with at least one unsaturated functional group is capable of copolymerizing when exposed to actinic radiation. The polyisocyanate comprises structural units with the formula (1): wherein: X is an electron-attracting group; R1, and R2 are hydrogen atoms, a saturated or unsaturated aliphatic or cycloaliphatic radical, or an aromatic or araliphatic radical; and n is an integer from 0 to 5. A process for producing this polyisocyanate is also disclosed.

  • Process for coating substrates
    Patent number: 6790485
    Abstract: The present invention relates to a process for coating a substrate by applying to a substrate a coating composition containing A) at least one compound which contains at least two (meth)acrylate groups and at least one isocyanate-reactive group and which is free from isocyanate groups and blocked isocyanate groups, B) at least one blocked polyisocyanate, which does not contain any ethylenically unsaturated groups and C) at least one photoinitiator, curing the coating composition by the action of UV light and post-curing by increasing the temperature of the coating.
