- a radically polymerizable resin and a cationic polymerizable resin may be mainly used in the ultraviolet curable ink composition.
- the radically polymerizable resin is not suitable for curing the thin film because it is impaired in curing due to oxygen, and is not suitable for bezel pattern formation due to its low adhesion to the glass substrate because of its large shrinkage.
- cationic polymerization type resin it is generally advantageous to cure the thin film because the curing shrinkage rate is low and the influence by oxygen is small.
- the ultraviolet curable ink composition used by this invention contains an epoxy resin as a cationic curing component.
- the epoxy resin is selected from a bisphenol type epoxy resin, a novolak type epoxy resin, a glycidyl ester type epoxy resin, a glycidyl amine type epoxy resin, a linear aliphatic epoxy resin, a biphenyl type epoxy resin, and an alicyclic epoxy compound. It may be one kind or a mixture of two kinds.
- the alicyclic epoxy compound may mean a compound including at least one epoxidized aliphatic ring group.
- the epoxidized aliphatic ring group means an epoxy group bonded to an alicyclic ring, for example, a 3,4-epoxycyclopentyl group, 3,4-epoxy Cyclohexyl group, 3,4-epoxycyclopentylmethyl group, 3,4-epoxycyclohexylmethyl group, 2- (3,4-epoxycyclopentyl) ethyl group, 2- (3,4-epoxycyclohexyl) ethyl group, 3- Functional groups, such as a (3, 4- epoxycyclo petyl) propyl group or 3- (3, 4- epoxy cyclohexyl) propyl group, can be illustrated.
- the hydrogen atom constituting the alicyclic ring in the above may be optionally substituted with a substituent such as an alkyl group.
- a substituent such as an alkyl group.
- the content of the epoxy resin is preferably 5 to 50% by weight, more preferably 10 to 30% by weight based on the total weight of the ultraviolet curable ink composition. When it exceeds 50 weight%, coating property will fall, and when it is less than 5 weight%, a sensitivity will fall.
- the ultraviolet curable ink composition contains an oxetane resin as another cationically polymerizable monomer.
- the oxetane resin is a compound having a four-membered cyclic ether group in its molecular structure, and can act to lower the viscosity of the cationic cured ink composition (for example, less than 50 cPs at 25 ° C).
- oxetane compound For example, "Alon oxetane OXT-101", “Alon oxetane OXT-121", “Alon oxetane OXT-211", “Alon oxetane OXT-221" of Toagosei Co., Ltd., or "Alonoxetane OXT-212" etc. can be used. These can be used individually or in combination of 2 or more types.
- the content of the oxetane resin is preferably 15 to 75% by weight, and more preferably 40 to 60% by weight based on the total weight of the ultraviolet curable ink composition. If it exceeds 75% by weight, the curing degree is low, and if it is less than 15% by weight, the viscosity rises and the coating property is lowered.
- the oxetane resin of this invention can be used including the oxetane compound which has one oxetane ring, and the oxetane compound which has two oxetane rings.
- the viscosity and the flexibility of the membrane can be adjusted.
- the oxetane compound having one oxetane ring The content range of the oxetane compound having two oxetane rings is in the range of 1: 1.16 to 1: 3. It is preferable to use.
- the present invention is characterized in that the content ratio of the epoxy resin: oxetane resin is 1: 0.5 to 1: 6.
- the coating composition of the composition may be excellent due to the low viscosity of the composition, but the curing sensitivity may be lowered.
- the ratio is less than 1: 0.5, the viscosity of the composition may be high. Therefore, the coating property may be lowered.
- the ink composition of the present invention includes, as a cationic photopolymerization initiator, a compound which produces a cation species or bronsted acid by irradiation of ultraviolet rays, for example, an iodonium salt or a sulfonium salt, but is not limited thereto. It doesn't happen.
- the iodonium salt or sulfonium salt may cause a curing reaction to form a polymer by reacting monomers having unsaturated double bonds contained in the ink during UV curing, and may use a photosensitizer according to polymerization efficiency.
