Definitions
- the present invention relates to an active energy ray-curable resin composition for optical three-dimensional modeling. More specifically, the present invention is excellent in storage stability and storage stability over time, has a small increase in viscosity even when stored for a long time at a high temperature, and nevertheless, it is based on active energy such as light. It is a product that can produce optical three-dimensional objects with high curing sensitivity and excellent dimensional accuracy, molding accuracy, water resistance, moisture resistance, and mechanical properties by irradiating active energy rays with high productivity at a high molding speed. The present invention relates to an active energy ray-curable resin composition for optical three-dimensional modeling. Background technology>
- a typical optical three-dimensional modeling technology (hereafter, “optical three-dimensional modeling” is sometimes referred to as “stereolithography”) is to use a computer so that a desired pattern can be obtained on the liquid surface of the liquid photocurable resin in a container.
- a predetermined thickness is cured by selectively irradiating the ultraviolet laser controlled in the above, and then one layer of the liquid resin is supplied on the cured layer, and then the ultraviolet laser is similarly irradiated as described above.
- There is a method of obtaining a three-dimensional structure by repeating a layering operation for obtaining such a hardened layer by curing. This stereolithography method is widely used at present because it can easily produce a considerably complicated shaped object in a relatively short time.
- photocurable resin compositions for stereolithography include photocurable resins containing radically polymerizable organic compounds, photocurable resins containing cationically polymerizable organic compounds, composites, and radical polymerizable organic compounds.
- Various photocurable resin compositions such as photocurable resin yarns and the like containing both a compound and a thiothion polymerizable organic compound have been proposed and used.
- examples of the radical polymerizable organic compound include (meth) acrylate compounds, urethane (meth) acrylate compounds, polyester (meth) acrylate compounds, polyether (meth) acrylate compounds, and epoxy compounds.
- (Meth) acrylate compounds and the like are used, and as the cationically polymerizable organic compound, for example, various epoxy compounds, cyclic acetal compounds, thiirane compounds, butyl ether compounds, ratatones and the like are used. .
- a cationic thione polymerization initiator present in the system generates cationic species by light irradiation. It is linked in a chain with the cationically polymerizable organic compound, and the cationically polymerizable organic compound opens the ring and the reaction proceeds.
- a photocurable resin composition based on a cationically polymerizable organic compound such as an epoxy compound is used, generally, compared with a case where a photocurable resin composition based on a radically polymerizable organic compound is used. As a result, a molded article having a small dimensional accuracy with a small shrinkage of the obtained photocured product can be obtained.
- a photocurable resin composition containing a thiothion polymerizable organic compound such as an epoxy compound has insufficient storage stability and stability over time, and may cause an increase in viscosity during storage. Viscosity rises rapidly within a short period of time, losing fluidity and making it unusable for stereolithography. For this reason, in areas with high temperatures or in summer, the photocurable resin composition containing the cation polymerizable organic compound must be refrigerated, transported, or stored in a cool place. Is a problem. This is not an exception in a photocurable resin composition containing both a cationically polymerizable organic compound such as an epoxy compound and a radically polymerizable organic compound.
- an aromatic sulfonium salt of a Group Vila element (Patent Document 9 ), And aromatic ionic salts of Group VIa elements (see Patent Document 10), and aromatic ionic salts of Group Va elements (see Patent Document 11).
- Polymerization initiators are known. However, in any case, no consideration is given to improving the storage stability of the photocurable resin composition.
- a photopolymerization initiator of a cationically polymerizable organic compound the following formula (II):
- M is an antimony atom or a phosphorus atom, and the stone line between 3 + and] ⁇ ? 6 — indicates an ionic bond.
- the photocurable resin yarn composition containing the conventional force thione polymerization initiator mainly composed of bissulfonium salt is excellent in photocuring sensitivity but inferior in storage stability and stability over time, Viscosity easily increased during storage, and especially at high temperatures, the viscosity rapidly increased in a short period of time and lost its fluidity, making it difficult to use it for stereolithography and the like.
