摘要： An aqueous inkjet ink for forming a colour upon heat treatment includes a) an immobilized leuco dye; b) a colour developing agent or colour developing agent precursor; and c) optionally an opthothermal converting agent; wherein the leuco dye is immobilized by being covalently bonded to polymeric particles or by being included in the core of capsules composed of a polymeric shell surrounding a core.

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.
