Abstract
The invention is a composition of matter used in the making of raised characters for use in signs, and a method of manufacturing raised characters made from the composition. The matter is a polymerizable composition comprising a silicone rubber compound, and about 10 to about 50 weight percent of a silica filler based on the weight of the polymerizable composition. Moreover, the composition of matter is a curable composition comprising a vinyl resin selected from a vinyl plastisol or vinyl organosol, and about 10 to about 50 weight percent of a silica filler based on the weight of curable composition. The invention also includes a method of manufacturing raised characters for use in signs comprising machining the characters from a partially cured polymerizable material. A further method is disclosed for manufacturing raised characters for use in signs, comprising partially curing a liquid polymerizable or curable composition in a form having a relatively uniform thickness, and, machining the characters from the partially cured composition. Finally, a method for making signs using the raised characters of the invention is disclosed.
