Abstract
Un composé nucléophile alcanoylé est ponté sous forme de polyuréthanne par un dérivé polyisocyanate ou sous forme de polyester par un dérivé polyacide. On obtient ainsi une encre désensibilisante pour impression en offset humide sur une surface acceptrice d'un ensemble autocopiant chimique.An alkanoylated nucleophilic compound is bridged in the form of polyurethane by a polyisocyanate derivative or in the form of polyester by a polyacid derivative. A desensitizing ink for wet offset printing is thus obtained on an acceptor surface of a carbonless chemical assembly.
Description
L'invention a pour objet une encre désensibilisante pour impression en offset humide sur une surface acceptrice d'un ensemble autocopiant chimique, comprenant au-moins deux feuilles superposées dont les faces en regard présentent, l'une un enduit électrophile accepteur, et l'autre un enduit nucléophile susceptible de produire une réaction chromogène avec ledit enduit électrophile accepteur.The subject of the invention is a desensitizing ink for wet offset printing on an acceptor surface of a carbonless chemical assembly, comprising at least two superimposed sheets, the facing faces of which have, one an electrophilic acceptor coating, and the another a nucleophilic coating capable of producing a chromogenic reaction with said accepting electrophilic coating.
Par le brevet anglais N° 1.433-469, on connaît déjà des encres désen- sibilisantes contenant du polypropylène glycol de poids moléculaire compris entre 400 et 5000 permettant d'imprimer en typographie, flexographie ou hélio-. graphie la surface acceptrice d'un ensemble autocopiant et d'empêcher ainsi toute formation colorée dans les zones ainsi imprimées, lors d'une écriture ou frappe subséquente sur l'ensemble autocopiant.For the English Patent No. 1433-469, are already known DESEN inks - sibilisantes containing molecular weight polypropylene glycol of between 400 and 5000 for printing letterpress, flexographic or helio-. prints the acceptor surface of a carbonless assembly and thus prevents any colored formation in the areas thus printed, during a subsequent writing or typing on the carbonless assembly.
Comme indiqué dans le brevet anglais N° 1.525.269, la titulaire du brevet anglais N° 1.433.469 n'avait toutefois pas réussi à formuler une encre à base de polyalkylène glycol permettant d'imprimer en offset humide la surface acceptrice d'un ensemble autocopiant chimique.As indicated in the English patent N ° 1.525.269, the owner of the English patent N ° 1.433.469 had however not succeeded in formulating an ink based on polyalkylene glycol allowing to print in wet offset the acceptor surface of a carbonless chemical assembly.
Comme décrit dans le brevet suisse N° 628.288, la titulaire de la présente invention a réalisé une encre désensibilisante, à base de polyalkylène glycol ou d'autre composés nucléophiles alcanoxylés de poids moléculaire élevé, permettant d'imprimer la surface acceptrice d'un ensemble autocopiant chimique par impression en offset humide, à la suite d'une alcanoxylation à un degré tel que leur équilibre hydrophile-lipophile (HLB) soit compris entre 2 et 9 afin de permettre, d'une part, un transfert continu de l'encre des rouleaux. encreurs sur les zones hydrophobes de la plaque d'impression humidifiée d'une presse offset, et, d'autre part, de neutraliser des zones correspondantes de la surface acceptrice de l'ensemble autocopiant chimique.As described in Swiss Patent No. 628,288, the owner of the present invention has produced a desensitizing ink, based on polyalkylene glycol or other high molecular weight alkanoxylated nucleophilic compounds, making it possible to print the acceptor surface of a set chemical carbonless by wet offset printing, following alkanoxylation to a degree such that their hydrophilic-lipophilic balance (HLB) is between 2 and 9 in order to allow, on the one hand, a continuous transfer of the ink rollers. inkers on the hydrophobic areas of the printing plate moistened with an offset press, and, on the other hand, to neutralize corresponding areas of the acceptor surface of the carbonless chemical assembly.
Afin d'augmenter le poids moléculaire du composant désensibilisant l'encre selon l'invention, est caractérisée en ce que le composé nucléophile alcanoxylé est ponté par un dérivé polyisocianate aliphatique ou aromatique ou encore par un derive polyacide aliphatique ou aromatique, qui permet en plus d'améliorer le transfert de l'encre sur le train d'encrage de la presse offset humide. Il en résulte encore un débit d'encre d'épaisseur constante par les rouleaux du train d'encrage. Ce film d'encre résiste particulièrement bien au choc résultant de l'émulsion de l'eau de mouillage dans l'encre avant d'être transféré successivement sur la plaque d'impression offset, puis sur le blanchet et finalement sous forme d'une couche d'encre désensibilisante, à raison de 1,5 à 5 gr/m2, sur un support de papier.In order to increase the molecular weight of the ink desensitizing component according to the invention, is characterized in that the alkanoxylated nucleophilic compound is bridged by an aliphatic or aromatic polyisocianate derivative or by an aliphatic or aromatic polyacid derivative, which also makes it possible to improve the transfer of the ink onto the inking train of the wet offset press. This also results in an ink flow of constant thickness by the rollers of the inking train. This ink film is particularly resistant to the shock resulting from the emulsion of fountain water in the ink before being transferred successively to the offset printing plate, then to the blanket and finally in the form of a layer of desensitizing ink, at a rate of 1.5 to 5 gr / m2, on a paper support.

En présence d'acide p-toluène-sulfonique en tant que catalyseur on obtient ainsi un polyester. Comme la température de réaction est supérieure à 100°C, la formation d'ester s'accompagne d'élimination d'eau récupérable dans une colonne Dean-Starke. Le produit augmente de poids moléculaire qui se traduit par une augmentation de viscosité.To the alkanoxylated derivative which can be written HO (R) OH, a stoichiometric amount of diacid can be added. In the presence of p-toluenesulfonic acid as a catalyst, a polyester is thus obtained. As the reaction temperature is above 100 ° C, the formation of ester is accompanied by elimination nation of recoverable water in a Dean-Starke column. The product increases in molecular weight which results in an increase in viscosity.
On fait réagir à une température supérieure à 100°C et en présence de 0,2 parties d'acide p-toluène-sulfonique, 96 parties de polyèthylène glycol avec 4 parties d'acide succinique et on obtient le polyester succinique. A 65 parties de polyester succinique on ajoute sous agitation 35 parties de résine phénolique modifiée acide, puis on chauffe jusqu'à dissolution complète de la résine. Le vernis ainsi obtenu possède une vicosité de 120 poises (mesuré à 25°C sur viscosimètre cône-plaque de Haake).Reacted at a temperature above 100 ° C and in the presence of 0.2 parts of p-toluene sulfonic acid, 96 parts of polyethylene glycol with 4 parts of succinic acid and the polyester succinic is obtained. To 65 parts of succinic polyester is added with stirring 35 parts of acid modified phenolic resin, then heating until complete dissolution of the resin. The varnish thus obtained has a viscosity of 120 poises (measured at 25 ° C. on a Haake cone-plate viscometer).
-On mélange sur une broyeuse à 3 cylindres, 70 parties de ce vernis polyester avec 10 parties de dioxyde de titane, 2 parties d'oxyde de silicium, 6 parties de carbonate de calcium et 10 parties de polyester succinique liquide.- 70 parts of this polyester varnish are mixed on a 3-cylinder grinder with 10 parts of titanium dioxide, 2 parts of silicon oxide, 6 parts of calcium carbonate and 10 parts of liquid succinic polyester.
L'encre ainsi obtenue présente de bonne propriétés neutralisantes, un bon équilibre eau/encre (HLB=Hydrophilic Lipophilic Balance: 4 [i 1]), une viscosité de 120 poises, un tirant initial de 150 unités (mesuré sur Tack-OScope de Test- print à une vitesse de 100 m/min. à 25°C) et un bon transfert sur le train d'encrage.The ink thus obtained has good neutralizing properties, a good water / ink balance (HLB = Hydrophilic Lipophilic Balance: 4 [i 1]), a viscosity of 120 poises, an initial draft of 150 units (measured on Tack-OScope of Test-print at a speed of 100 m / min at 25 ° C) and good transfer to the inking train.
On fait réagir à une température supérieure à 100°C et en présence de 0,2 parties d'acide p-toluène-sulfonique, 94 parties de polyéthylène glycol avec 6 parties d'acide citrique et on obtient le polyester citrique.Reacted at a temperature above 100 ° C and in the presence of 0.2 parts of p-toluene sulfonic acid, 94 parts of polyethylene glycol with 6 parts of citric acid and the citric polyester is obtained.
A 68 parties de polyester citrique on ajoute sous agitation 38 parties de résine phénolique modifiée acide, puis on chauffe jusqu'à dissolution complète de la résine. Le vernis ainsi obtenu possède une viscosité de 140 poises à 25°C.To 68 parts of citric polyester 38 parts of acid modified phenolic resin are added with stirring, then heating until the resin is completely dissolved. The varnish thus obtained has a viscosity of 140 poises at 25 ° C.
On mélange sur une broyeuse à 3 cylindres, 67 parties de vernis polyester avec 10 parties de dioxyde de titane, 2 parties d'oxyde de silicium, 6 parties de carbonate de calcium et 13 parties de polyester citrique liquide.67 parts of polyester varnish are mixed on a 3-cylinder mill with 10 parts of titanium dioxide, 2 parts of silicon oxide, 6 parts of calcium carbonate and 13 parts of liquid citric polyester.
L'encre ainsi obtenue présente de bonnes propriétés neutralisantes en offset humide (HLB: 4 [± 11), une viscosité de 110 poises et un tirant initial de 155 unités.The ink thus obtained has good neutralizing properties in wet offset (HLB: 4 [± 11), a viscosity of 110 poises and an initial draft of 155 units.
Selon une variante, on peut faire la synthese du polyester avec un polyacide aromatique tel que l'acide isophtalique ou téréphtalique.Alternatively, the polyester can be synthesized with an aromatic polyacid such as isophthalic or terephthalic acid.
Selon une autre variante, on peut faire la synthèse de polyester à partir de diéthylène triamine propoxylée de poids moléculaire analogue.According to another variant, it is possible to synthesize polyester from propoxylated diethylene triamine of similar molecular weight.
On peut encore substituer une partie du polyacide aliphatique ou aromatique par :
- - soit des acides gras tels que l'acide ricinoléique, l'acide oléique, etc.
- - soit des huiles grasse qui réagissent vers 250°C par transestérification,
- - soit avec les alkydes grasses porteuses de groupes acides.
- - or fatty acids such as ricinoleic acid, oleic acid, etc.
- - or fatty oils which react around 250 ° C by transesterification,
- - either with fatty alkyds carrying acid groups.
Afin de rendre l'humidification des zones hydrophiles de la plaque 'd'impression en offset humide plus aisée, on peut émulsionner dans la masse d'encre une partie ou la totalité de l'eau requise pour assurer la saturation de ces zones.In order to make the moistening of the hydrophilic areas of the wet offset printing plate easier, part or all of the water required to ensure saturation of these areas can be emulsified in the ink mass.
