Patent attributes
The invention relates to a multi-stage curing ink comprising compounds for forming at least one organic matrix, which is cured via radical polymerisation and which curing can be initiated by radiation, and comprising alkoxysilane in a quantity of 10 to 60 wt. %, preferably 20 to 50 wt. %, in relation to the total formulation, in order to form at least one inorganic matrix, which is cured via non-radical polymerisation and which curing can be initiated thermally, the ink also including a structure-reinforcing polymer having a number average molecular mass (Mn) of greater than 3000 g/mol, preferably greater than 10,000 g/mol, and particularly preferably greater than 30,000 g/mol, and the viscosity of the ink at 50° C. is in the region of 6 to 15 mPa·s, particularly preferably in the region of 9 to 11 mPa·s, measured with a Brookfield rheometer using a UL adapter with a rotational speed of 50 rotations per minute.
