N2 - A resin composition comprising [a] at least one compound C1 having at least one terminal alkyne functional group (such as propargyl, butynyl or pentynyl), e.g. propargyl carbonate, carbamate, ether, ester, butynyl carbonate, carbamate, ether, ester or pentynyl carbonate, carbamate, ether, ester; [b] at least one compound C2 having at least two thiol functional groups; [c] at least one compound C3 having at least one carbon-carbon double bond, and has at least a functional group such as a vinyl functional group, an allyl functional group, an (meth) acrylate group; [d] at least one photoinitiator; and [d] optionally at least one stabiliser. Also disclosed is use of the resin composition in an ink; a kit comprising the resin composition; a printing method comprising the resin composition; a polymer, an article, such as a medical device or a biomedical device such as an implant, a bone substitute, a tissue substitute or a dental product, comprising the resin composition. Further disclosed is a composition comprising at least one compound C1 having at least one terminal alkyne functional group (such as propargyl, butynyl or pentynyl), e.g. propargyl carbonate, carbamate, ether, ester, butynyl carbonate, carbamate, ether, ester or pentynyl carbonate, carbamate, ether, ester and/or at least one compound C3 having at least one carbon-carbon double bond, and has at least a functional group such as a vinyl functional group, an allyl functional group, an (meth) acrylate group; at least one compound C2 having at least two thiol functional groups; and at least one stabiliser, selected from a radical scavenger, a phosphorous containing compound and a complexing agent.

AB - A resin composition comprising [a] at least one compound C1 having at least one terminal alkyne functional group (such as propargyl, butynyl or pentynyl), e.g. propargyl carbonate, carbamate, ether, ester, butynyl carbonate, carbamate, ether, ester or pentynyl carbonate, carbamate, ether, ester; [b] at least one compound C2 having at least two thiol functional groups; [c] at least one compound C3 having at least one carbon-carbon double bond, and has at least a functional group such as a vinyl functional group, an allyl functional group, an (meth) acrylate group; [d] at least one photoinitiator; and [d] optionally at least one stabiliser. Also disclosed is use of the resin composition in an ink; a kit comprising the resin composition; a printing method comprising the resin composition; a polymer, an article, such as a medical device or a biomedical device such as an implant, a bone substitute, a tissue substitute or a dental product, comprising the resin composition. Further disclosed is a composition comprising at least one compound C1 having at least one terminal alkyne functional group (such as propargyl, butynyl or pentynyl), e.g. propargyl carbonate, carbamate, ether, ester, butynyl carbonate, carbamate, ether, ester or pentynyl carbonate, carbamate, ether, ester and/or at least one compound C3 having at least one carbon-carbon double bond, and has at least a functional group such as a vinyl functional group, an allyl functional group, an (meth) acrylate group; at least one compound C2 having at least two thiol functional groups; and at least one stabiliser, selected from a radical scavenger, a phosphorous containing compound and a complexing agent.
