Definitions
- the present invention relates to a radiation-curable ink jet composition
- Inkjet printing is well suited to applications such as short-run label printing
- the inks used for this process are of generally low viscosity and are based on organic or aqueous solvent systems In either case, the solvent content is relatively high
- aqueous-based systems also present problems It is relatively difficult to drive-off the water in the drying process Such aqueous systems also tend to have a poor affinity for non-absorbent surfaces
- UV-curable inks it is usual to formulate UV-curable inks using a monomeric or oligomeric base vehicle
- polymer materials do not give the low viscosity required for a UV-curable ink-jet ink suitable for the aforementioned application, without the use of organic solvents
- polymerisable monomers are in principle better-suited to achieving low viscosity, it is a problem to find a suitable monomer which would have sufficiently low toxicity and high thermal stability yet which gives a sufficiently flexible and durable film upon curing
- Analogous non-conductive inks are disclosed in EP-A-0 540 203 which cross- references EP-A-0 465 309. Both of the latter documents envisage use of monofunctional and polyfunctional acrylate monomers. Ethoxylated monofunctional and trifunctional (but not difunctional) materials are recited. These documents also teach that the inks may optionally contain up to 70% by weight of difunctional material and optionally up to 10% by weight of trifunctional material.
- UV-curable photoresists for printed circuit board applications and which contain low levels of ethoxylated acrylate monomers are disclosed in US-A-5 270 368.
- one aspect of the present invention provides a radiation-curable ink jet composition comprising, from 80% to 95% by weight of polyfunctional alkoxylated and/or polyfunctional polyalkoxylated acrylate monomer material; and a photoinitiator
- the amounts of the acrylate monomer, photoinitiator, and colourant will vary according to the particular equipment and application. However, typically, the amount of photoinitiator is from 1% to 15% by weight of the total composition.
- the polyfunctional alkoxylated or polyalkoxylated acrylic monomer material preferably comprises one or more di- or tri-acrylates.
- alkoxylated or polyalkoxylated acrylic monomers of higher functionality may also be used alone or together with one or more di- and/or trifunctional materials.
- the only requirement is that the total amount of the polyfunctional material (alkoxylated + polyalkoxylated) is in the range of from 80% to 95% by weight of the total composition.
- the number of alkoxy groups is from 1 to 20 per molecule of the monomer.
- the or each alkyleneoxy group is a C2-C4 alkyleneoxy. Most preferred are ethoxy (EO) or propoxy
- Suitable polyfunctional alkoxylated or polyalkoxylated acrylates may be selected from alkoxylated, preferably ethoxylated or propoxylated, varients of the following neopentyl glycol diacrylates, butanediol diacrylates, trimethylpropane tri-acrylates and glyceryl triacrylate.
- compositions according to the invention may also contain some monofunctional alkoxylated or polyalkoxylated acrylated monomer material, for example at up to 10% by weight of the total composition, e.g selected from one or more of alkoxylated, e.g. ethoxylated or propoxylated, variants of the following tetrahydrofurfuryl acrylates, cyclohexyl acrylates, alkyl acrylates, nonyl-phenol acrylate and polyethylene or polypropylene glycol acrylates.
- alkoxylated e.g. ethoxylated or propoxylated
- compositions according to the present invention may also comprise minor amounts of non-alkoxylated radiation curable monomer material, either monofunctional or polyfunctional, preferably up to no more than 5% by weight of the total composition, e.g. selected from one or more of octyl acrylate, decyl acrylate, N- vinylpyrollidone, ethyl digtycol acrylate, isobornyl acrylate, ethyl-hexyl acrylate, lauryl acrylate, butanediol monoacrylate, ⁇ -carboxyethyl acrylate, isobutyl acrylate, polypropylene glycol monomethacrylate, 2-hydroxyethyl methacrylate, difunctional (meth)acrylic acid esters, e.g.
- photoinitiators are commercially available and a non- exhaustive selection of appropriate types include xanthone or thioxanthone types, benzophenone types, quinone types and phosphine oxide types.
- a co-initiator should also be included, most preferably of the amine or aminobenzoate type In that case, it is preferred for the total photoinitiator (primary initiator plus co-initiator) to be within the aforementioned preferred range.
- typical co-initiators are aminobenzoate and acrylated amine co-initiators, these generally being used with the xanthone/thioxanthone types of primary photoinitiator.
- the present invention provides a radiation curable ink jet composition That is to say, a composition which is curable by application of suitable radiation such as ultra-violet (UV) radiation or electron-beam radiation.
- a composition which is curable by application of suitable radiation such as ultra-violet (UV) radiation or electron-beam radiation.
- suitable radiation such as ultra-violet (UV) radiation or electron-beam radiation.
- UV radiation ultra-violet
- a composition may be only a substantially colourless curable varnish or a substantially colourless radiation-curable base to which a colourant may be added
- the term colourant covers both materials which endow an actual visual colour and/or another optical property such as fluorescence Colourants are typically included in amounts of from 1% to 10% of total colourant(s) by weight of the total composition
- colourants may be considered as falling into two classes, namely dyes, which are substantially soluble in the ink composition, and pigments, which are dispersed in the ink composition in the form of fine particles, if necessary with the aid of a suitable dispersant.
- Pigments may be selected from a wide range of classes, for example, Pigment Red 57: 1, Pigment Red 52.2, Pigment Red 48.2, Pigment Blue 15.3, Pigment Green 7, Pigment Yellow 83, Pigment Yellow 13, Pigment White 6, Pigment Black 7.
- a non-exhaustive list of examples of such pigments include the following from the Irgalite range ex CLBA. Rubine L4, Bordeaux CM, Red 2BP, Blue LG, Green GLN, Yellow B3R and yellow LBG, as well as Tioxide RHD6 (ex Tioxide) and Special Black 250 (ex Degussa)
- Ink compositions according to the present invention optionally may also comprise one or more minor ingredients, for example, surfactants, levelling additives, photoinitiator stabilisers, wetting agents and pigment stabilisers.
- the latter may for example be of polyester, polyurethane or polyacrylate types, especially in the form of high molecular weight block co-polymers, and would typically be inco ⁇ orated at from 2.5% to 100% by weight of the pigment.
- Suitable examples are Disperbyk 161 or 162 (ex BYK Chemie) or Solsperse ex Zeneca Suitable photoinitiator stabilisers include those disclosed in EP-A-0 465 039
- Suitable surfactants are preferably of non-ionic type, for example Fluorad FC430 (ex 3M Corp.) Such surfactants (when present) are preferably included in an amount of 0 1% to 10% by weight of the total composition.
- compositions according to the present invention are preferably substantially free or totally free of organic solvent. Thus, they preferably contain less than 10%, more preferably less than 5%, especially less than 1% and most preferably less than 0.1% of organic solvents) as expressed by weight of the total composition.
