Sheet for forming burned pattern

Abstract

A sheet for forming a burned pattern is provided which comprises a ceramic green sheet layer (1) to be burned and a pressure-sensitive adhesive layer (2), wherein the pressure-sensitive adhesive layer comprises either a single layer decomposable at low temperature and leaving a decreased amount of carbonaceous residues after burning or a laminated layer comprising at least two layers of an inner pressure-sensitive adhesive layer (21) which is the low-temperature-decomposable layer and an outer pressure-sensitive adhesive layer (22) having resistance to water washing. The pressure-sensitive adhesive layer of the sheet for forming a burned pattern shows excellent provisional adhesion to adherends before burning. In particular, the outer pressure-sensitive adhesive layer shows such adhesive strength that the sheet is prevented from peeling off upon water washing. Even when the ceramic green sheet layer is one formed by a conventional manner, the pressure-sensitive adhesive layer disappears at lower temperature during burning the green sheet layer while showing satisfactory thermal decomposability. The sheet for forming a burned pattern as a whole is thus less apt to leave carbon, tar, etc.
