Abstract:
A laser markable article comprising a first laser markable layer capable of forming a colour upon exposure to UV radiation, a second and optionally a third laser markable layer capable of forming a colour upon exposure to IR radiation, characterized in that the second or third laser markable layer comprises a specific polymethine infrared radiation absorbing dye (IR dye). Also a colour laser marking method is disclosed wherein a first colour is formed upon exposure to UV radiation and a second and optionally a third colour upon exposure to IR radiation.
Abstract:
The invention provides an inkjet method for producing a solder mask in the manufacture of a Printed Circuit Board. By using a solder mask inkjet ink containing at least one photo-initiator, at least one free radical polymerizable compound and at least one RAFT compound as adhesion promoter, a high quality solder mask withstanding the high thermal stress during the soldering process while maintaining excellent physical properties, may be produced.
