[0238] 6. Preparation method of ink

[0239] The ink of the present invention can be prepared by mixing each component used as a raw material by a known method.

[0240] In particular, the ink of the present invention is preferably prepared by mixing the above-mentioned component (A) and the polymerization initiator (C), and optionally the monomer (B) and / or other components, and then using, for example, fluorine The obtained solution was filtered and degassed by a resin-made membrane filter. The ink prepared in the above-described manner is excellent in ejectability by an ink jet apparatus.

[0241] The viscosity of the ink of the present invention at 25° C. measured by an E-type viscometer is preferably 200 mPa·s or less, more preferably 1 mPa·s to 200 mPa·s, still more preferably 2 mPa·s to 150 mPa·s, and particularly Preferably, it is 3 mPa·s to 100 mPa·s. When the viscosity of the ink of this invention is in the said range, the ejection characteristic by an inkjet appa...

[0279] As the monomer (a-1), 3.0 g of dicyclopentyl acrylate, namely Fancryl FA-513AS (trade name; Hitachi Chemical Co., Ltd., also referred to as "FA-513AS" hereinafter), was used as the monomer (a- 2) 3.0 g of cyclohexyl methacrylate i.e. Light EsterCH (trade name; Kyeisha Chemical Co., Ltd., hereinafter also referred to as "CH-MA"), tricyclodecane dimethanol as monomer (B) 2.5 g of diacrylate, IRR214-K (trade name; Daicel-Cytec (stock)), and 2-(4-methylbenzyl)-2- as a polymerization initiator (C) (Dimethylamino)-1-(4-morpholinophenyl)butan-1-one, i.e., IRGACURE379 (trade name; BASF Japan Co., Ltd.) 1.2 g was mixed to obtain a solution, and the pore diameter was used. The filtrate (inkjet ink 1) was obtained by filtering with a 0.2 μm ultra-high molecular weight polyethylene (hydrophobic) membrane filter (Nihon Entegris Co., Ltd.).

[0280] Using an E-type viscometer (Toki Sangyo Co., Ltd. TV-22 (trade name), the same applies hereinafter), the viscosity of the in...

Abstract

A photocurable inkjet ink, comprising a monofunctional polymerizable monomer component (A) comprising a monofunctional polymerizable monomer (a-1) having a condensed cyclic hydrocarbon group or polycyclic hydrocarbon group, and a monofunctional polymerizable monomer (a-2) having a monocyclic hydrocarbon group, and a polymerization initiator (C).

Description

technical field [0001] The present invention relates to a photocurable inkjet ink, which can be preferably used in the manufacture of display elements such as liquid crystal display elements or electroluminescence (EL) display elements, or printed circuit boards, flexible circuit boards, semiconductor packages, etc. Electronic circuit substrates such as substrates and solar cell substrates. More specifically, the present invention relates to a photocurable inkjet ink suitable for protecting conductors such as metal wiring and electrodes constituting a predetermined circuit pattern, and cover films, solder resists, and the like of substrates. Background technique [0002] Conventionally, when manufacturing electronic circuit boards such as printed wiring boards, flexible wiring boards, semiconductor package substrates, and solar cell substrates, conductors such as metal wirings and electrodes that constitute a predetermined circuit pattern formed on the substrate, and the sub...
