Patent ID: 7482419

Claim:
A silsesquioxane resin wax comprising at least 40 mole % of siloxy units having the formula (R 2 R′SiO 1/2 ) x (R″SiO 3/2 ) y , where x and y have a value of 0.05 to 0.95 and a certain y/x ratio, R is an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, R′ is a monovalent hydrocarbon having 18-40 carbon atoms, and R″ is a monovalent hydrocarbon group having 1 to 8 carbon atoms or an aryl group, provided R′ and the y/x ratio are selected such that the silsesquioxane wax has a melting point greater than 30° C.
