METHOD OF OBTAINING A DECORATIVE PATTERN ON A TRANSPARENT SUBSTRATE AND TRANSPARENT SUBSTRATE BEARING SUCH DECORATIVE PATTERN

摘要

Method for obtaining design on transparent substrate such as glass or glass ceramic comprises stage (a) deposition, on at least one part of one face of substrate, of primary layer of photosensitive resin comprising at least a sensitising agent and at least a photosensitive compound which essentially consists of polymer with high degree of crosslinking, d which can absorb particular solids; (b) isolating certain bands of primary layer to increase d and capacity for absorption of said polymer; (c) depositing second layer based on mineral particles; and (d) submitting substrate to cycle of thermal treatment to fix mineral particles. Also claimed are transparent substrate treated by said method in which decorated surface has light transmission = 0.07-87.1% and resolution = 150D.p.i.; and application of method in production of multicoloured decorated glasses or glass ceramics and in production of e.g. plasma screens.
