Esacure ONE by IGM Resins is a difunctional oligomeric alpha hydroxy ketone. It is a type I photoinitiator. Provides through and surface cure. Formula (1) was prepared using both Esacure M (A) and Esacure ONE (B). The results of the tests performed are reported in figures 1 & 2. Curing was. ONE offers very low odor levels and low migration but suffers from low solubility. A liquid version, Esacure ONE 75, is a 75% solution of ONE in 25% ethozylated.

As additional photoinitiators oligomeric compounds such as for example oligomeric alpha hydroxyl ketones e. IS Free format text: The C 1 -C 22 alkyl group in the above mentioned alkoxylates is linear or branched, saturated or unsaturated and preferably C 6 -C FG2A Ref document number: A homogenous liquid blend according to claim 1 wherein the dsacure is present. MK Free format text: A1 Designated state s: We’re sorry, but the industry you have selected is not currently available in your chosen language.
B1 Designated state s: In one embodiment esacuge organic diluent is present. By contrast, Example 9 had a viscosity similar to honey and could be directly poured into the OPV.
The surfactant can be a blend of all classes of alkoxylated surface active substances described previously. Oxime ester derivatives of benzocarbazole compounds and their use as photoinitiators in photopolymerizable compositions.
This is in contrast to the reference Escaurewhich due to the incompatibility does not give a useful waterborne UV-paint. Liquid photoinitiator product forms of the following photoinitiators were prepared: Most necessary For analysis and a reasonably well-functioning website.
A at least one ethylenically unsaturated photopolymerizable compound and. The surfactant is e.
Table 1 shows that the reactivity of Example 9 is comparable to Esacure KIP in the pure product form. The formulations were stirred for a total of 15 min. Higher active contents are obtainable as compared to previous solutions like the waterborne dispersions of photoinitiators described in EP Lamberti and EPB1 Ciba and in GB Minesota Mining In addition the inventive homogenous liquid blends show better storage stability, especially at elevated temperatures, as there are no heterogeneous photoinitiator particles which may irreversibly settle like in the case of a dispersion.
Esacurd are compounds sold under the Trade Mark Brij such as polyoxyethylene 4 lauryl ether Brij 30 or polyoxyethylene 20 cetyl ether Brij 58polyoxyethylene 20 stearyl ether Brij 78 and polyoxyethylene 20 oleyl ether Brij 92 or polyethylene glycol monomethyl ether MPEG.
Further polyols which are suitable are oligoesters having hydroxyl end groups. Higher active contents are obtainable as compared to previous solutions like the waterborne dispersions of photoinitiators described in EP Lamberti and EPB1 Ciba and in GB Minesota Mining In addition the inventive homogenous liquid blends show better storage stability, especially at elevated temperatures, as there are no heterogeneous photoinitiator particles which may irreversibly settle like in the case of a dispersion.
The optional organic onee is chosen from the group consisting of high boiling inert liquids based on ester and or ether compounds like: PLFP Year of fee payment: Active-energy-ray-curable composition, active-energy-ray-curable ink, composition stored container, two-dimensional or three-dimensional image forming apparatus, two-dimensional or three-dimensional image forming method, cured material, and structure.
Pne Ref legal event code: AT Kind code of ref document: A dispersion solid particles of the photoinitiator is obtained. The product form is a clear, colorless to yellow liquid.

Further examples of unsaturated oligomers are unsaturated polyester resins, which are usually prepared from maleic acid, phthalic acid and one or more diols and have molecular weights of from about to Examples of alkoxylates of alkine-alcohols or alkine-diols are product sold under the Esachre Examples of suitable alkoxylated liquid surface active agents include also compounds in which a straight or branched C 1 -C 22 alkyl chain is connected through the residue of a linking group as defined above to multifunctional alcohols like trimethylolpropane, sugar derivatives like sorbitan esters, triglycerides like castor oil and the like.
Benzene, (1-methylethenyl)-, homopolymer, ar-(2-hydroxy-2-methyl-1-oxopropyl) derivs.
In addition it is also possible to employ vinyl ether monomers and oligomers, and also maleate-terminated oligomers with polyester, polyurethane, polyether, polyvinyl ether and epoxy main chains. Also high energy input is required to prepare the product form dispersing process. RO Free format text: For reference, a photoinitiator free sample of the formulations was treated in the same way.
The unsaturated compounds may include one or more olefinic double bonds. They may be of low monomeric or high oligomeric molecular mass. The mixture is cooled slowly to room temperature. The sorbitan esters are sold under the tradename Tween, like polyoxyethylene 20 sorbitan monolaurate Tween 20polyoxyethylene 20 sorbitan monopalmitate Tween 40polyoxyethylene 20 sorbitan monostearate Tween 60polyoxyethylene 20 sorbitan tristearate Tween 65polyoxyethylene 20 sorbitan monooleate Tween 80polyoxyethylene 20 sorbitan trioleate Tween Photocurable ink set, and printing method, printing apparatus and printed matter each using the same.
The acrylate peak at approx. Further, borate compounds can be used as coinitiators. Also preferred are non-ionic surfactants derived from ethoxylated esters of fatty acids with glycerine or sorbitan, such as polyoxyethylene glycerine monostearate, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan-monostearate, polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan tristearate, polyoxyethylene sorbitan trioleate.
