Definitions
- 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.
- 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 surface acceptor of '' a carbonless chemical assembly by wet offset printing, following an 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 of the ink rollers on the hydrophobic zones of the printing plate moistened with an offset press, and, on the other hand, to neutralize corresponding zones of the acceptor surface of the carbonless carbon assembly.
- HLB hydrophilic-lipophilic balance
- the alkanoxylated nucleophilic compound is bridged by an aliphatic or aromatic polyisocyanate 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 / m 2 , on a paper support.
- a desensitizing ink according to the invention for wet offset printing of the acceptor surface of a carbonless carbon assembly, can be formulated as follows.
- 70 parts of a varnish obtained by reaction of 63 parts of polypropylene glycol (PM 2550) with 5 parts of hexamethylene triisocyanate and addition of 32 parts of acid modified phenolic resin, with 13 parts, are mixed on a three-cylinder grinder. parts of titanium dioxide, 1 part of silicon oxide and 6 parts of calcium carbonate.
- 60 parts of a varnish obtained by reacting 58 parts of polypropylene glycol (PM 2500) with 8 parts of ricinoleic acid and 10 parts of trimethylolpropane isocyanated with 3 moles of toluylene diisocyanate are mixed on a three-cylinder mill and adding 24 parts of neutral esterified rosin resin, with 20 parts of titanium dioxide, 2 parts of silicon oxide and 6 parts of calcium carbonate.
- This ink has a rheology suitable for printing in wet offset.
- This ink has a rheology suitable for printing in wet offset.
- This ink has a rheology suitable for printing in wet offset.
- part or all of the water required to ensure saturation of these areas can be emulsified in the ink mass.
