Coatings (1, 2) on a glass substrate (3) are formed by laying down layers of different thermosetting materials one upon the other in powder form on surfa ce (4). The powder of transparent coating (1) has a higher-cure rate than that of colour coating (2) so that when heat is applied, coating (2) remains in the melt condition while the coating hardens, to bond with and enable rolling ou t onto coating (1), as well as bonding with a backing (5). Materials of different cure-rates are also used for bonding substrates together by bringi ng the two materials together while one is partly-cured and the other in the me lt condition.
