Abstract
A flexible 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, moisture, 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 color filters and electroconductive layers in flat panel displays.
