Abstract
Embodiments of the invention relate to a resin composition, in particular suitable for printing, a kit comprising components of the resin composition, printing methods, a polymer obtained by the printing methods, an article comprising or formed from the polymer, uses thereof, and a composition. The resin composition comprises at least one compound C1 having at least one terminal alkyne functional group; at least one compound C2 having at least two thiol functional groups; at least one compound C3 having at least one carbon-carbon double bond; at least one photoinitiator; and at least one stabilizer.
Claims18
A composition comprising:
- at least one compound C1 having at least one terminal alkyne functional group and/or at least one compound C3 having at least one carbon-carbon double bond;
- at least one compound C2 having at least two thiol functional groups;
- at least one stabilizer selected from the group consisting of a radical scavenger, a phosphorous containing compound and a complexing agent;
- and
- a light absorber,
- wherein the at least one stabilizer comprises at least one phosphorous containing compound, and wherein the at least one phosphorous containing compound comprises at least one phosphoric acid ester.
A kit comprising:
- at least one compound C1 having at least one terminal alkyne functional group and/or at least one compound C3 having at least one carbon-carbon double bond;
- at least one compound C2 having at least two thiol functional groups;
- at least one stabilizer selected from the group consisting of a radical scavenger, a phosphorous containing compound and a complexing agent;
- and
- a light absorber,
- wherein the at least one stabilizer comprises at least one phosphorous containing compound, and wherein the at least one phosphorous containing compound comprises at least one phosphoric acid ester.
The printing method according to 14, wherein the method further comprises at least one of the following steps:
- heating the resin composition;
- and/or
- post-curing the polymer during and/or after irradiating the at least part of the resin composition;
- and/or
- cleaning the polymer.
The printing method according to 14, further comprising a step of cleaning the polymer, wherein the step of cleaning comprises contacting the polymer with a cleaning composition comprising an alkaline compound, a surfactant and an appropriate solvent.
The printing method according to 14, wherein the method comprises at least one of the following features:
- the printing method is a three-dimensional printing method;
- and/or
- the printing method is a solvent-free printing method;
- and/or
- the energy-carrying activation beam comprises electromagnetic radiation.
