摘要： A thermal recording sheet having on a support a thermal recording layer adapted for developing color when heated has an outermost surface layer formed by bringing it into contact with the surface of a smooth body when it is in a wet state, drying it and separating it from the surface of the smooth body. The sheet has a surface which is so smooth that when a first straight line extending in parallel to the centerline of a roughness curve as obtained in accordance with the method of JIS B0601 crosses the roughness curve with a contact ratio of 10%, a second straight line extending in parallel to the centerline and between it and the first straight line and having a distance of 1.5 .mu.m from the first straight line crosses the roughness curve with a contact ratio of at least 80%. The sheet is, therefore, easy to bring into intimate contact with a thermal head and is of high image quality and sensitivity. If the smooth body has a glossy or dull surface, it is possible to produce a thermal recording sheet having a uniformly glossy or dull surface without lowering its image quality or sensitivity.

摘要： A process for preparing ceramic moldings containing no organic matter with retention of their original shapes which comprises mixing 100 parts by weight of ceramic powders and/or fibers, 0.1 to 50 parts by weight of papermaking organic fibers and/or wet-end additives and 3 to 200 parts by weight of mountain leather, molding the resulting mixture to obtain an unburned molding having enough mechanical strength to withstand molding processings and, subjecting the unburned molding to burning treatment.
