Abstract
Provided is a photocurable composition comprising: a) at least one monomer or/and oligomer bearing at least one functional group selected from the group consisting of (meth) acrylate-functional group, vinyl-functional and allyl-functional group or at least one monomer or/and oligomer bearing at least two of said functional groups with one of them being an allyl group, b) at least one polythiol bearing at least one secondary thiol group, and c) at least one photoinitiator. The said composition can be used in coatings, inks, adhesives and varnishes. A finished cured product made of the said composition is suitable for optical, electronic and opto-electronic applications.
Claims18
A photocurable thiol-ene composition comprising:
- a) 10 to 80 wt % of at least one aliphatic or cycloaliphatic urethane oligomer bearing at least one allyl-functional group or at least one aliphatic or cycloaliphatic urethane oligomer bearing at least two functional groups selected from the group consisting of (meth)acrylate-functional group, vinyl-functional group and allyl-functional group with one of said at least two functional groups being an allyl group,
- b) 10 to 50 wt % of at least one polythiol bearing at least one secondary thiol group,
- c) at least one photoinitiator, and
- e) at least one reactive diluent selected from the group consisting of monofunctional or multifunctional (meth)acrylates, wherein said reactive diluent is copolymerizable with.
