摘要： A color laser markable composition includes at least a first and a second Diffusion Hindered Molecular Assembly (DHMA), each including a leuco dye and, respectively, a first and second sensitizer. With the laser markable composition, at least two different colors may be formed in a single layer.

摘要： An inkjet method for producing a solder mask in the manufacture of a Printed Circuit Board uses 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 is produced.
