Abstract:
A laminate is disclosed wherein a thin borosilicate glass substrate is bonded to a support, which is preferably a transparent plastic support. The glass substrate protects the support from scratches, moistures, solvents and gases, and improves the dimensional and thermal stability of the support, whereas the support protects the glass from breakage. The use of borosilicate significantly reduces the chance of breakage compared to e.g. sodium or chemically hardened glass. The laminate can be used for carrying a functional layer such as an image recording layer. The laminate is especially suitable for carrying colour filters and electroconductive layers in flat panel displays.
Abstract:
A method of plating a Printed Circuit Board (PCB) including the steps of: - providing a PCB including a solder mask; - exposing at least part of the solder mask with UV radiation having an energy density of at least 2000 mJ/cm2; - forming a protected area on the exposed solder mask by printing and curing a radiation curable composition, the radiation curable composition comprising at least one polymerizable compound and at least one photoinitiator; - plating an unprotected area of the exposed solder mask; - removing at least partially the protected area from the solder mask.
