Definitions
- Printing presses usually operate at high speeds; the.
- absorption is of little or no aid and possible printing speeds; are materially less.
- One method generally em ployed to dry or set inks appliedi to such materialsis simpleevaporation of the solvent; often with heat.
- A- particular object is to provide novel means. for rendering ink im pressions upon a printing. surface substantially nonsmearing in character.
- a specific object is toeffect the rapid and thorough setting, or drying of an. ink fol lowing its application to a printing surface.
- this invention broadly comprises accelerating the drying of a pigmented coating composition containing av polymerizable, organic polyhydroxy compound, by subjecting saidcomposition to reaction with. an organic, ester. of a fourth group. metal selected from titanium and zirconium.
- the invention comprises. substantially instantaneously drying an ink composition applied to a paper or other surface by subjecting said: composition (containing a colorant and as a vehicle a polymerizable,. organic polyhydric conium ortho-ester of a primary aliphatic alcohol con-.

- ink type coating compositions used to produce characters in writing or printing upon a paper or' other suitable surface
- these are employed for use inthe'usualtype; copper plates, etc., and comprise syrupy, non smudgingi so-called lithographic varnish compositions: exhibiting a suitable consistency and adapted to be readilytransferred from conventional ink rolls to the typeandfrom thetype. to the paper or other surface to which the-.ink' isto' be applied.
- Suitablezlinseed oil and rosin or other oil vehicle in which lampblack or any other suitable inorganic or organic colorant, such; as conventional white or colored pigments or dyestuffs, or mixtures thereof to-obtain various shades or tints; are: incorporated or dispersed.
- lampblack or any other suitable inorganic or organic colorant such as conventional white or colored pigments or dyestuffs, or mixtures thereof to-obtain various shades or tints; are: incorporated or dispersed.
- suitable inorganic or organic colorant such as conventional white or colored pigments or dyestuffs, or mixtures thereof to-obtain various shades or tints; are: incorporated or dispersed.
- suitable inorganic or organic colorant such as conventional white or colored pigments or dyestuffs, or mixtures thereof to-obtain various shades or tints; are: incorporated or dispersed.
- utilizablea colorants include titanium dioxide, zinc sulfide;. lithop
- The: coating orinkcomposition used, to be effectively useful in accordance: with the invention, must contain, either as a..vehicle1or"as' a component part of the compositiorna polyhydroxy compound such as glycol, glycerol, pentaerythritol,,castor oil, nitrocellulose, etc.
- the vehicle can consist ventirely of the compound or be composed of suitable mixtures of polyhydroxy compounds.
- a solid or semi-solid form 'is used, resort can be advantageously had to a polyhydroxy compound type solvent, such as glycerin or glycol, etc., to effect dissolution and subsequent use in such solvent.
- the metal ester will react with both the vehicle and solvent to produce an insoluble ink film comprising a polymer of vehicle plus solvent plus ester.
- more than one vehicle can be used in a given composition, as may various mixtures and eombinations'of utilizable vehicles and solvents.
- the polyhydroxy compound-containing ink or like coating composition upon being conventionallyimpressed upon a surface as by transfer from, for example, an ink roll to a paper, textile, glass, metal, etc., is immediately subjected to contact with, preferably, a stoichiometric quantity of a contemplated metal ester.
- a contemplated metal ester Those found to be of particular value for use in the invention comprise the organic esters of titanium or zirconium. Surprisingly, all metal esters are not satisfactory foruse herein since silicon esters, for example, prove of little or no value for use. It appears that the desired insolubilization and rapid set of polyhydroxy vehicles is attained only with esters of metals which have a coordination number higher than their valence.
- zirconium and titanium have coordination numbers of 6, while silicon has a coordination number of 4.
- essentially any titanium or zirconium ester (or alcoholate) or mixtures of such compounds can be used in the invention. They are readily formed by replacing a hydroxy hydrogen of an alcohol with titanium or zirconium.
- One useful method of preparation comprises reacting an alchol with a halide, preferably the chloride, of titanium or zirconium in the presence of ammonia, and in accordance with theprocedures of U. S. Patent No. 2,187,821. Because of their availability and commercial attractiveness, use'is preferred of titanium or zirconium ortho esters of alcohols having from 1-8 carbon atoms in their primary chains; e.
- esters of such compounds include ethyl titanate, butyl titanate, octyl titanate, phenyl titanate, phenyl ethyl titanate, and cyclohexyl titanate, etc., as well as the zirconates of these representative titanates.
- the ester may be employed in the form of a liquid or solution, or, if a solid, it may be dissolved in a suitable anhydrous solvent prior to use.
- a solvent which also tends to insolubilize the particular polyhydroxy vehicle present is especially satisfactory, giving a combined and accentuated setting effect.
- Such contact of the ester with the coating composition can, for example, be effected by superimposing the ester upon the ink or other coating impression through overprinting, rolling or spraying, or by immediately subjecting the printing surface to a vaporous atmosphere of the ester while an elevated temperature condition prevails over such coated surface.
- any alcohol or like byproducts which form are readily removed as vapors.
- the ester and organic compound In the interaction between the ester and organic compound, the latter is substantially instantaneously polymerized to render the ink or coating insoluble in either water or 'oils.
- the insolubilization occuring within one second or less, depending upon the particular polyhydroxy compound and ester utilized, results in a non-tacky print even before solvent evaporation to obviate the necessity of employing open-flamevaporization or other solvent .removal methods and enable resort to a much less complex and generally more rapid printing operation. Additionally, the print, whendry, will not set off from the paper or. other surface to which it is applied.
- R represents an alkyl, alkenyl, aryl, alkaryl, or
- x is at least 2 and preferably at least 3

Description
Printing presses usually operate at high speeds; the.
more rapid the rate at which. printingv matter can. be produced, naturally the greater the output in. a given period of time or the shorter the time required for. a
given output. For eXampIe neWsprintis generally, passed through presses at about'l6'00'. ft. per minute; and. mag azines and other periodicals which have a definite publication deadline are printed on' high speed presses also. The greatest problem in achieving rapid printing lies in the printing inks. In order to wet paper or textile, glass or metal, or the like, and thus effect arelativel'y lasting impression thereon, ink. must initially be fluid. However, such fluidity is disadvantageous in that, if the printed surface contacts another, surface while. the ink is still'wet, the ink will smear and become blurred or blotted. Further, the ink; once thoroughly dry, should.
become insoluble, so" that'it' will not smear if'the. printed surface should later become Wetted. It is thus vitalfor clear impressions'that the ink be dry and non-tackybefore" the printed surface is" contacted; and that' it' be permanently insolubilized. There isa continuous; search by the trade for methods whereby inks may" be dried and:
rendered permanent more and more quickly;
In the case of newsprint, the porosityof the paper employed allows the ink to be quickly" absorbed" therein. It is because of this that the above-mentioned high print ing speed of 1600 ft; per'minute is possible. case of magazines and other periodicals which use a less porous paper, and in the case of printing on metals, glass, various fabrics. and other less pervious surfaces,
absorption is of little or no aid and possible printing speeds; are materially less. One method generally em ployed to dry or set inks appliedi to such materialsis simpleevaporation of the solvent; often with heat. At
best, this is time-consuming andlcostly. Magazine print' ispassed. over an open flame at temperatures-as h1ghias 650. C., and thesolvent is thus quickly: flash-vaporized;
However, even by this shorter procedure, the.- highest usually obtainable press. speed is about 900 ft; perminute; furthermore, the intenseheat serves;to;weaken: and: generally degrade the fibers of the paper;.resulting in costly web': breaks and shutdowns. Another commercial meth od is to dissolve asolid resin in a solvent and then pres cipitate it from such solution by addition of. a; second? material in which it is" insoluble. Thus, a. resin vehicle may be dissolved in ethylene glycol and mixed with: a.
pigment to form a conventional. ink. This ink may then be impressed on a printing surface. If the impression is brought into contact with water (generally' added as steam), the vehicle will be precipitated from the glycol' solution and thereby insolubilizedl In; such a system the second solvent must be miscible with the first; but" the vehicle must be insoluble in a mixture of the two. Such requirements seriously-restrict the number offsystemspossible; and the rate of insolubilization, even with satisfactory solvent systems, is relatively slow; no really fast drying method utilizing this principle havingbeen developed.
As; will; be. evident, the. problem:. of insolubilizing or rapidly setting, employed in:- various. printing: ape
In the States Patent 0 plications is one of major. importance and-a. great. need exists for a novel procedure whereby suchinks may be more rapidly dried, the. possible. speedoff printing; con
sequently increased}. and7printing. costs, advantageouslylessened. It is among the objects. of. this invention, therefore, to meet this problcm and toprovide novel'. pro.- cedures. for accomplishing such objects. A- particular object is to provide novel means. for rendering ink im pressions upon a printing. surface substantially nonsmearing in character. A specific object is toeffect the rapid and thorough setting, or drying of an. ink fol lowing its application to a printing surface. Other objects and advantages of my invention will be apparent from the ensuing description thereof.
These objects are attained in this invention which broadly comprises accelerating the drying of a pigmented coating composition containing av polymerizable, organic polyhydroxy compound, by subjecting saidcomposition to reaction with. an organic, ester. of a fourth group. metal selected from titanium and zirconium.
In a more, specific and preferred. embodiment, the invention comprises. substantially instantaneously drying an ink composition applied to a paper or other surface by subjecting said: composition (containing a colorant and as a vehicle a polymerizable,. organic polyhydric conium ortho-ester of a primary aliphatic alcohol con-.
taining-from l-8 carbon atoms.
Since the-ihvention is' particularly useful (though not limited) to the quick drying of ink type coating compositions used to produce characters in writing or printing upon a paper or' other suitable surface, it will be described in itsapplication to such adaptation and particularly in printing inks. These are employed for use inthe'usualtype; copper plates, etc., and comprise syrupy, non smudgingi so-called lithographic varnish compositions: exhibiting a suitable consistency and adapted to be readilytransferred from conventional ink rolls to the typeandfrom thetype. to the paper or other surface to which the-.ink' isto' be applied. They consist ofa suitablezlinseed oil and rosin or other oil vehicle in which lampblack or any other suitable inorganic or organic colorant, such; as conventional white or colored pigments or dyestuffs, or mixtures thereof to-obtain various shades or tints; are: incorporated or dispersed. Examples of utilizablea colorants: include titanium dioxide, zinc sulfide;. lithopone; blue: to green phthalocyanines, lead chromateg.vermillion venetian red, cobalt blue, indigo, iron blue Milorijblue,.chrome.-. greens, azo maroons, etc.
The: coating orinkcomposition used, to be effectively useful in accordance: with the invention, must contain, either as a..vehicle1or"as' a component part of the compositiorna polyhydroxy compound such as glycol, glycerol, pentaerythritol,,castor oil, nitrocellulose, etc. Polyhydroxy compounds; having. a; molecular weightv of at least SOO'and. containing. more than one free hydroxyl group.- adapted; to react: with. a titanium. or zirconium ester to.. induce;. quick drying and insolubilization of the composition following its application; to. a. surface are preferred for use; Among examples; of these compounds, thoseofnitrocellulbse, phthalic anhydrideaglycliquid.or can-,bepresent as.a solute. If a solidorsemisolid, .it-.must. b.e capable of beingdissolved in convenventionalorganicsolvents inaccordance with customary. printing: practices If. a liquid, it; should: polymerize to a solid, or if asolnbleisolidtin should-polymerizeto en 'Patented Jan. 31, 1956 Y insoluble form. It can be incorporateddirectly in the vehicle or'composition to form a component part of each; or, if preferred, the vehicle can consist ventirely of the compound or be composed of suitable mixtures of polyhydroxy compounds. Thus, where a solid or semi-solid form 'is used, resort can be advantageously had to a polyhydroxy compound type solvent, such as glycerin or glycol, etc., to effect dissolution and subsequent use in such solvent. In such instance the metal ester will react with both the vehicle and solvent to produce an insoluble ink film comprising a polymer of vehicle plus solvent plus ester. If desired, more than one vehicle can be used in a given composition, as may various mixtures and eombinations'of utilizable vehicles and solvents.
The polyhydroxy compound-containing ink or like coating composition, upon being conventionallyimpressed upon a surface as by transfer from, for example, an ink roll to a paper, textile, glass, metal, etc., is immediately subjected to contact with, preferably, a stoichiometric quantity of a contemplated metal ester. Those found to be of particular value for use in the invention comprise the organic esters of titanium or zirconium. Surprisingly, all metal esters are not satisfactory foruse herein since silicon esters, for example, prove of little or no value for use. It appears that the desired insolubilization and rapid set of polyhydroxy vehicles is attained only with esters of metals which have a coordination number higher than their valence. Thus, zirconium and titanium have coordination numbers of 6, while silicon has a coordination number of 4. In practice, essentially any titanium or zirconium ester (or alcoholate) or mixtures of such compounds can be used in the invention. They are readily formed by replacing a hydroxy hydrogen of an alcohol with titanium or zirconium. One useful method of preparation comprises reacting an alchol with a halide, preferably the chloride, of titanium or zirconium in the presence of ammonia, and in accordance with theprocedures of U. S. Patent No. 2,187,821. Because of their availability and commercial attractiveness, use'is preferred of titanium or zirconium ortho esters of alcohols having from 1-8 carbon atoms in their primary chains; e. g., methyl, butyl, secondary butyl, propyl, isopropyl, tertiary-butyl, ethyl, amyl, and like esters, substituted or unsubstituted. Representative esters of such compounds include ethyl titanate, butyl titanate, octyl titanate, phenyl titanate, phenyl ethyl titanate, and cyclohexyl titanate, etc., as well as the zirconates of these representative titanates. As in the case of the polyhydroxy vehicle, the ester may be employed in the form of a liquid or solution, or, if a solid, it may be dissolved in a suitable anhydrous solvent prior to use. In the latter instance, a solvent which also tends to insolubilize the particular polyhydroxy vehicle present is especially satisfactory, giving a combined and accentuated setting effect. Such contact of the ester with the coating composition can, for example, be effected by superimposing the ester upon the ink or other coating impression through overprinting, rolling or spraying, or by immediately subjecting the printing surface to a vaporous atmosphere of the ester while an elevated temperature condition prevails over such coated surface. In the latter instance, any alcohol or like byproducts which form are readily removed as vapors.
In the interaction between the ester and organic compound, the latter is substantially instantaneously polymerized to render the ink or coating insoluble in either water or 'oils. The insolubilization occuring within one second or less, depending upon the particular polyhydroxy compound and ester utilized, results in a non-tacky print even before solvent evaporation to obviate the necessity of employing open-flamevaporization or other solvent .removal methods and enable resort to a much less complex and generally more rapid printing operation. Additionally, the print, whendry, will not set off from the paper or. other surface to which it is applied.
in which R represents an alkyl, alkenyl, aryl, alkaryl, or
arylalkyl grouping, x is at least 2 and preferably at least 3, Y is a polyfunctional organic radical, and Z is an integer greater than 1. The reaction shown is between a titanium ester of a monohydroxy organic compound, e. g., an alcohol and a polyhydroxy compound which may be represented by nitrocellulose or partially-hydrolyzed polyvinyl acetate. The reaction may of course proceed even further, and there may be various modifications and other chemical compounds formed. While polymerization and consequent insolubility can be achieved with practically any polyhydroxy vehicle, proper selection to fit the particular objective is recommended. For instance, glycerol may be reacted with a titanium or zirconium ester and will set rapidly but optimum results are not achieved in certain instances since the product tends to flake on of non-porous surfaces so that a relatively permanent impression upon such surfaces may not be obtained. On the other hand, a phthalic anhydrideglycerol resin of low molecular weight, though also utilizable and providing satisfactory binder action, tends to set up slowly in such applications and hence is not preferred for use where the highest setting speed is desired limitation of such invention, are given:

The resulting ink was then impressed upon paper by means of a rubber stamp. Meanwhile, butyl zirconate was dissolved in toluene to provide a 50% by weight solution. Immediately after stamping the paper with the ink, the zirconium ester solution was applied thereover by means of a rubber roller.
