This invention relates to polyurethane resins having reduced adhesion to other materials. It particularly pertains to polyurethane interlayers, especially interlayers utilized in laminated safety glass articles. More particularly, this invention relates to polyurethane compositions comprising the reaction product of an organic polyisocyanate and an organic polyol which has reduced adhesion to other materials due to the inclusion therein of a proton containing compound of phosphorus, preferably acid organic phosphorus compounds. |
