Abstract
The present invention relates to the field oxidative drying inks suitable for offset, letterpress and intaglio printing. In particular, it relates to oxidative drying inks for printing by an offset process, letterpress process or intaglio process on a non-porous substrate selected from the group consisting of polymer materials, composite materials, metals or metalized materials and combinations thereof, said oxidative drying ink comprising at least one oxidative drying varnish and one or more neutral manganese complex compounds.
Claims15
An oxidative drying ink for printing by an offset process, letterpress process or intaglio process on a non-porous substrate selected from the group consisting of polymer materials, composite materials, metals or metalized materials and combinations thereof, said oxidative drying ink comprising at least one oxidative drying varnish and one or more neutral manganese complex compounds having the formula (I)
- wherein
- R1 are identical or different from each other and selected from the group consisting of C1-C18-alkyls, C1-C18-alkenyls, C1-C18-alkynyls and C3-C12-cycloalkyls;
- n is an integer in a range between 1 and 5;
- X, Y and Z are identical or different from each other R2COO−;
- R2 are identical or different from each other and selected from the group consisting of H, C1-C18-alkyls, C1-C18-alkenyls, C1-C18-alkynyls, C3-C12-cycloalkyls, C3-C12-cycloalkenyls, C1-C12-heterocycloalkyls and C7-C12-aralkyls.
A use of the one or more neutral manganese compounds having the formula (I)
- wherein
- R1 are identical or different from each other and selected from the group consisting of C1-C18-alkyls, C1-C18-alkenyls, C1-C18-alkynyls and C3-C12-cycloalkyls;
- n is an integer in a range between 1 and 5;
- X, Y and Z are identical or different from each other R2COO−;
- R2 are identical or different from each other and selected from the group consisting of H, C1-C18-alkyls, C1-C18-alkenyls, C1-C18-alkynyls, C3-C12-cycloalkyls, C3-C12-cycloalkenyls, C1-C12-heterocycloalkyls and C7-C12-aralkyls,
- as an oxypolymerization catalyst for oxidative drying inks for printing by an offset process, letterpress process or intaglio process on a non-porous substrate selected from the group consisting of polymer materials, composite materials, metals or metalized materials and combinations thereof.
