Definitions
- the present invention relates to radiation curable polyester oligomers, to polymerizable compositions, and to methods of coating.
- U.S. Patent No. 4,522,465 (Bishop, et. al.) discloses buffer-coated and overcoated optical glass fiber in which the topcoat has the high strength and high tensile modulus combined with good elongation and solvent resistance associated with extruded jacket coatings, but which is applied by ordinary coating procedures and cured by exposure to ultraviolet radiation.
- the coating compositions comprise 30% to about 80% of linear diethylenic polyester polyurethanes which are the linear polyurethane reaction product of an organic diisocyanate with hydroxy-functional polyester formed by reacting a diol, such as ethylene glycol, with certain dicarboxylic acids, such as adipic acid.
- This polyurethane is end capped with a monoethylenically unsaturated monohydric alcohol, e.g. the hydroxy-functional acrylate of caprolactone dimer derived from caprolactone and 2-hydroxyethyl acrylate supplied by Union Carbide Corporation under the designation Tone M-100.
- a monoethylenically unsaturated monohydric alcohol e.g. the hydroxy-functional acrylate of caprolactone dimer derived from caprolactone and 2-hydroxyethyl acrylate supplied by Union Carbide Corporation under the designation Tone M-100.
- U. S. Patent No. 4,581 ,407 discloses an essentially isocyanate-free polyurethane polyurea polyethylenic oligomer which is unusually strong and elastic and is thus useful as a binder for a coating containing a magnetic pigment.
- This oligomer is the reaction product of: (1) organic diisocyanate; (2) a stoichiometric deficiency of difunctional materials reactive therewith and consisting essentially of: (A) polyoxyalkylene glycol having a molecular weight of from 200 to 1000; (B) dihydric bisphenol-based alkylene oxide adduct containing from 2-10 alkylene groups per molecule; and (C) polyoxyalkylene diprimary amine having a molecular weight of from 150 to 800. In all of these, the alkylene groups contain from 2-4 carbon atoms.
- the polyurethane polyurea so-constituted is capped with monohydric ethylenic compound, such as the adduct of caprolactone dimer and 2-hydroxy ethyl acrylate, to provide a molecular weight in the range of about 5,000 to about 30,000.
- This polyethylenic oligomer is cured by radiation exposure, such as an electron beam, using from 5% to 25%, based on total polymer solids, of polyethylenic polyhydroxyalkyl melamine.
- This invention relates to a compound having the formula:
- R is hydrogen or methyl
- R 2 is an alkylene group or substituted alkylene group (typically having less than six carbon atoms, more typically two or three carbon atoms),
- R 3 is an alkylene group or substituted alkylene group (typically having less than ten carbon atoms, more typically from four to six carbon atoms),
- R 4 is an aliphatic, aromatic, cycloaliphatic or heterocyclic radical (i.e. the residue of an organic isocyanate, including trimerized isocyanates, but excluding isocyanate-functional prepolymers of active hydrogen compounds) having a functionality of n, n is an integer from two to four (typically two or three), x is an integer from one to three, and y is an integer from one to five.
- This invention also relates to a polymerizable composition comprising a compound as set forth above and to a method of coating a substrate comprising polymerizing a composition comprised of the compound set forth above while in contact with a substrate.
- R 1 is hydrogen
- R 2 is an ethylene group
- R 3 is a pentamethylene group
- R 4 is the residue of isophorone di-isocyanate (and n is two), tetramethylxylene di-isocyanate (and n is two), toluene di-isocyanate (and n is two), or trimerized hexamethylene di-isocyanate (and n is three)
- x is one and y is two.
- this oligomer is prepared by forming a mixture of an acrylate- or methacrylate-functional and mono-hydroxyl-functional polyester oligomer and an isocyanate. These two components of the mixture then react in the presence of a urethane catalyst. The resulting product should contain essentially no unreacted isocyanate functionality.
- the olefinically unsaturated compounds employed for the preparation of the present acrylourethane oligomers may be monomeric or polymeric and are characterized by the presence of a single isocyanate-reactive moiety such as an active hydrogen group.
- the active hydrogen group is hydroxy.
- unsaturated addition-polymerizable monomeric organic compounds having a single isocyanate-reactive active hydrogen group are 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl acrylate, 2-hydroxypropyl methacrylate, N-hydroxymethyl acrylamide, N-hydroxymethyl methacrylamide, diethylene glycol monoacrylate, diethylene glycol monomethacrylate, glycerine dimethacrylate, trimethylol propane dimethacrylate, reaction products of polyether glycols of acrylic or methacrylic acid and the like.

- Preferred catalysts include stannous octoate, dibutyltin dilaurate, and other tin compounds; titanates such as tetraisopropyl titanate and butyl titanate; and the like.
- the reaction is carried out at a temperature of from about 100°C to about 400°C, preferably from about 120°C to about 130°C.
- the reaction may be carried out at atmospheric pressure, although higher or lower pressures may be used.
- the reaction is generally carried out in the presence of oxygen to inhibit polymerization of the hydroxyalkyl acrylate.
- the reaction is generally carried out for a period of from about 2 to about 20 hours.
- the reaction is carried out in the presence of a suitable inhibitor to prevent polymerization of the hydroxyalkyl acrylate double bond.
- inhibitors include the monomethyl ether of hydroquinone, benzoquinone, phenothiazine, methyl hydroquinone, 2,5-di-t-butylquinone, hydroquinone, benzoquinone and other common free radical inhibitors known in the art.
- the level of inhibitor used is less than 1000 parts per million, preferably less than 800 parts per million, and most preferably, less than 600 parts per million.
- a molar ratio of the lactone to hydroxyl groups in the ester of from about 1 :0.1 to about 1 :5, preferably from about 1 :0.3 to about 1:3 is typically utilized.
- R 4 is thus an aliphatic, aromatic, cycloaliphatic or heterocyclic radical.
- R 4 will contain from about 6 to about 36 carbon atoms, more typically from about 7 to about 24 carbon atoms.
- R 4 will typically be a hydrocarbon group or a heterocyclic group and is typically essentially free of urethane groups.
- Suitable polyfunctional isocyanates preferably contain on average 2 to at most 4 NCO groups.
- suitable isocyanates are 1 ,5-naphthalene di- isocyanate, 4,4'-diphenyl methane di-isocyanate (MDI), hydrogenated MDI (H12MDI), xylylene di-isocyanate (XDI), tetramethyl xylylene di-isocyanate (TMXDI), 4,4'-diphenyl dimethyl methane di-isocyanate, di- and tetraalkyl diphenyl methane di-isocyanate, 4,4 -dibenzyl di-isocyanate, 1 ,3-phenylene di ⁇ isocyanate, 1 ,4-phenylene di-isocyanate, the isomers of tolylene di-isocyanate (TDI), optionally in admixture, 1-methyl-2,4-di-isocyanatocyclohexane, 1
- Sulfur- containing polyisocyanates are obtained, for example, by reaction of 2 mol hexamethylene di-isocyanate with 1 mol thiodiglycol or dihydroxydihexyl sulfide.
- Other di-isocyanates are trimethyl hexamethylene di-isocyanate, 1 ,4-di- isocyanatobutane, 1 ,2-di-isocyanatododecane and dimer fatty acid di-isocyanate.
- Tri-isocyanate isocyanurates can be prepared by trimerizing di-isocyanates at elevated temperatures, e.g.
- the lactone-acrylate adduct is typically heated to a temperature of about from 40 to 100°C and typically about 60°C.
- a catalytic amount of a urethane catalyst e.g. dibutyl tin dilaurate, is added followed by addition of an isocyanate compound the formula:
- the amount of the isocyanate will be essentially equal (e.g. 1.01 :1 to 1 :1.01), on an equivalents basis, to the hydroxyl equivalents of the lactone-acrylate adduct.
- the reaction is typically heated, e.g. to a temperaure of about 80°C to about 100 °C, and held for about from 2 to about 4 hours or until the NCO content is ⁇ 0.5% by weight as measured for example by titration with dibutyl amine. Thereafter, the product is cooled prior to storage.
- the reaction with the isocyanate is entirely conventional being usually carried out at moderate temperature in the presence of a catalyst which promotes the urethane-forming reaction, such as dibutyl tin dilaurate. It is customary to limit the temperature, at least during the initial stages of the reaction, to about 60°C, and this can be done by slowing the rate of addition of one ofthe components.
- the temperature may be raised in the later stages ofthe reaction to promote completion of the reaction as measured by the consumption of the isocyanate functionality.
- the order of reaction is largely immaterial, it being possible to bring in the monohydric ethylenic compound either at the beginning, during the middle of the procedure, or as the last reactant. All of these variations are known in the art. It is usual herein to employ the di-isocyanate and the materials reactive therewith in stoichiometric amounts and to continue the reaction until the isocyanate functionality is substantially undetectable. As will be understood, these reactions are conveniently carried out neat with reactants that are liquid at the reaction temperature or in solvent solution, this being illustrated using the preferred tetrahydrofuran to maintain the liquid condition as the reaction proceeds.
- the compound of the present invention can be applied to a variety of substrates. These include, for example, porous stock such as paper and cardboard, wood and wood products, metals such as aluminum, copper, steel, and plastics such as P.V.C, polycarbonates, acrylic and the like.
- a suitable photoinitiator e.g., PHOTOMER 51 ® brand photoinitiator (benzyl dimethyl ketal)
- the compound is applied by methods such as spraying, rollcoating, flexo and gravure processes onto a selected substrate.
- the resulting coated substrate e.g., a paper, is typically cured under a UV or electron beam radiation.
- the compound may optionally be mixed with other substances such as pigments, resins, monomers and additives such as anti-oxidants and rheological modifiers.

- the rate of addition is such that the reaction temperature is maintained at about 60°C. After adduct addition is complete and the exotherm has subsided, the reaction temperature is raised to and held at about 90°C for 2 to 4 hours. The reaction is allowed to continue until no NCO groups are detectable by Fourier Transform Infra-red spectroscopy, i.e. less than 0.1% by weight NCO groups.
- the compound should exhibit a viscosity of 30,000 to 34,000 cps and should appear as a transparent, water-white liquid. When a suitable photoinitiator is added, the compound is drawn down on paper to effect a 1 mil dry film thickness and photocured.
