ACTINIC RADIATION CURED COATING COMPOSITION Russian patent published in 2012 - IPC C08G18/22 C08G18/24 C09D175/04 C08J7/18 C07F7/22 

FIELD: chemistry.

SUBSTANCE: invention relates to an actinic radiation cured coating composition containing a compound which contains at least two isocyanate groups, a compound which contains at least two hydroxyl groups, a sensitising agent and a photolatent catalyst for an isocyanate-hydroxl coupling reaction, where the photolatent catalyst is an organometallic compound, containing tin as a catalytically active metal, and where the atom of the catalytically active metal in the organometallic compound is not bonded to atoms of other metals. The invention also describes a method of coating a substrate, involving a step for applying said composition onto the substrate, as well as a set of parts for preparing said actinic radiation cured coating composition.

EFFECT: obtaining an actinic radiation cured coating composition having a good balance of long life and fast curing after application and irradiation, and leads to formation of cured coatings, the colour of which is not affected by coloured residues or photolatent catalyst fragments.
