摘要：PURPOSE:To provide the title protective sheet vanishing in baking in its bonded state to a ceramic powder form, giving good dimensional stability or cuttability in processes like cutting, hard to produce baking residues, excellent in the prevention of developing damages such as cracking or debonding, thus capable of producing favorable baked form. CONSTITUTION:The objective protective sheet consisting of (A) a film <=300mum thick, <=1000% in the breaking elongation by stretching and 2 30kg/mm<2> in elastic modulus made from a polymer vanishing through thermal decomposition in baking a ceramic powder form and, as necessary, having on the film (B) a tack layer similarly vanishing through thermal decomposition in baking the ceramic powder form. Thereby, no extension is developed in cutting the form, which constitute an unnecessary additional part to the form, thus avoiding the form's damages or stains due to such additional part and protecting the form even after its introduction into a baking oven, also dispensing with removing operation for the sheet after baking.
