A manufacturing method for printed circuit boards (1, 10) including the steps of:
a) inkjet printing a UV free radical curable inkjet ink on a substrate (2); b) UV curing the UV free radical curable inkjet ink on the inkjet printed substrate; and c) applying a thermal treatment on the UV cured inkjet printed substrate;
wherein the UV free radical curable inkjet ink contains at least a colorant, a free radical photoinitiator; a duofunctional monomer or oligomer and a polyfunctional monomer or oligomer; and 1 to 15 wt% of a silane compound according to Formula (I):
wherein, the linking group L represents a -CH 2 - group or an aliphatic chain having 2 to 10 carbon atoms optionally substituted in the aliphatic chain by a nitrogen or an oxygen; R1 represents a methoxy group; R2 and R3 independently represent a methoxy group or a C 1 - to C 4 -alkyl group; and R4 represents a functional group selected from the group consisting of an epoxy group, an amine group, a carbamate group, a trimethoxy silane group and an ureido group. |
