[ What is claimed is:] [9.]9. In a process for preparing a dental impression by contacting teeth with a tray containing a curable dental impression material, the improvement comprising coating the tray with a dental adhesive prior to introducing impression material into the tray, said dental adhesive comprising, in weight percent based on the total weight of component (A) through (D) of the composition:(A) from about 2% to about 20% of at least one organopolysiloxane rubber base;(B) from about 10% to about 25% of at least one organopolysiloxane pressure sensitive adhesive;(C) from about 30% to about 80% of at least one aliphatic unsaturation-functional organopolysiloxane M'Q resin;(D) from about 1% to about 20% of at least one Si--H functional organopolysiloxane crosslinking agent containing minimally 3 Si--H bound hydrogens per molecule on average; ponents (A) through (D) dissolved in(E) sufficient organic solvent to obtain a solids content of ingredients (A) to (D) of from 30 percent to about 70% based on the total weight of the adhesive, wherein the sum of the weight percentages of components A to D is 100% based on the weight of components A to D.
