摘要： A novel method of releasing from one another in a press pack, a plurality of back-to-back heat and pressure consolidated resin-impregnated laminates, e.g. decorative laminates, metal clad laminates, veneer backs and the like, which method comprises utilizing, as a separator sheet, a web of phenol-formaldehyde resin-free paper having a water absorption of at least about 200 seconds which has been sized on at least one side thereof, from an aqueous mixture, a water-soluble, alkaline earth or earth metal salt, e.g. a calcium salt such as calcium chloride, then coated on said sized side with a film of a mixture of a salt of alginic acid, such as sodium alginate, and either (1) a triglyceride or (2) hydrolyzed or non-hydrolyzed lecithin.
