Abstract From the Canadian patent

The technical field of the invention is specific to painting under glass (also called Reverse Painting on Glass). For centuries on 5 continents, day after day, an effective means of protecting the fragile back of paintings under glass is lacking. The invention consists in a new sealing process intended for painting under glass which backs onto a partition. Broadly speaking the advantages of the invention for paintings under glass are: 1) the painting is waterproofed; 2) it preserves the brilliance of the colours; 3) it improves the painting's resistance; 4) it protects the painting from its environment.
