Embodiment 1

[0325] This example illustrates the synthesis of a singlet oxygen quencher HS-1 to HS-4's.

[0326] Synthetic single-state oxygen quencher HS-1

[0327] 3- [(diethylamino) ethyl 2 - (3-ethoxy-3-oxo-propyl) - amino] propanoate (HS-1) is synthesized according to the following reaction scheme:

[0328]

[0329] The 51.06 g (0.51 mol) of ethyl acrylate was dissolved in 38g of ethanol. The solution was cooled to 0 ℃. Was added 23.24 g (0.2 mol) N, N- diethyl-ethylenediamine solution in 38g of ethanol. The reaction was continued at 0 ℃ 45 minutes. The mixture was heated to 21 ℃ and the reaction was continued for 24 hours at 21 ℃. 5g of ethanol was added a further 5g (0.05mol) acrylate and the reaction was continued for an additional 48 hours. The solvent was removed under reduced pressure and ethyl acrylate excess of HS-1 crude without further purification. HS-1 using LC MS analysis. Since transesterification with ethanol and methanol present, HS-1 of 96.5% of target structures, mono...

Embodiment 2

[0343] This example illustrates the reduction in the aldehyde emissions of the UV cured layer of the radiation-cured ink ink according to the present invention maintained a good shelf life.

[0344] Preparation of Red Dispersion DISP-M

[0345] By using Disperlux from Disperlux S.A.R.L., Luxembourg TM The dispersion was prepared according to the components of Table 5 for 30 minutes. Then, a Bachofen Dynomill ECM grinder grinding dispersion was grinded using a 0.4 mM ruthenium stabilized zirconia bead ("high-resistant zirconium zirconium abrasive medium" from TOSOH Co.). The mixture was circulated on the grinder for 2 hours. After grinding, the concentrated pigment dispersion was discharged into the container through a 1 micron filter.

Abstract

A radiation curable inkjet ink containing a polymerizable compound including a vinylether group or a vinylamide group; optionally an amine synergist including an alkanolamine group or a dimethyl benzoate group; optionally a Norrish Type II photoinitiator including a photoinitiating moiety selected from the group consisting of a thioxanthone group, a benzophenone group, a ketocoumarin group and a camphorquinone group; and a specific singlet oxygen quencher.

Description

Technical field [0001] The present invention relates to an inkjet ink that radiates, in particular, is a UV-cured ink ink for fabricating a decorative article for indoor decoration. Background technique [0002] The inkjet printing system is added to the industrial production line due to its enhanced reliability. The main advantage of inkjet is that it provides a high degree of flexibility, such as variable data printing allows small transport length, or even single printing without having a large number of printing preparation. The radiation-curable ink ink is particularly preferred because the high quality image can also be printed on the non-absorbent ink receiver, especially when the inkjet ink does not contain or contains a small amount of volatile organic solvent or water. [0003] Typical characteristics of ink ink inks must have a very low viscosity, such as from 5 to 15 MPa.s at a printing temperature to suck the droplet spray in a volume of the leather. In order to achi...
