Title:
HYDROXY FUNCTIONAL ALKYL CARBAMATE CROSSLINKERS
Document Type and Number:
WIPO Patent Application WO/2019/139969
Kind Code:
A1
Abstract:
A hydroxy functional alkyl carbamate is disclosed having the formula shown in claim 1, wherein R comprises a substituted or unsubstituted C1 to C36 alkyl group, an aromatic group, and/or a polymeric moiety; wherein each R1 is independently a hydrogen, alkyl having at least 1 carbon, or a hydroxy functional alkyl having 2 or more carbons and at least one Ri is a hydroxy functional alkyl having 2 or more carbons; and n is 2-6. The present invention is also directed to a composition, and substrates coated therewith, comprising a film-forming resin; and a hydroxy functional alkyl carbamate crosslinker having the formula shown above.
