Abstract: A sapphire member containing sapphire as a main constituent has a main surface parallel to a c-plane of a sapphire crystal. The sapphire member includes a plurality of terrace structure layers in at least a part of the main surface. Each terrace structure layer includes a terrace surface parallel to the c-plane and a side surface in contact with an edge line of the terrace surface. When viewed in a plan in a direction perpendicular to the main surface, the part of the main surface includes a plurality of the edge lines that are curved and are not parallel to one another.

Abstract: Disclosed is a novel high pullulan content product containing pullulan having an average molecular weight less than 250,000, said product being prepared by continuously cultivating a microorganism capable of producing pullulan in a nutrient culture medium containing a 10-20 w/v % saccharide while controlling the viscosity of the nutrient culture medium to a level below 30 cp. The product can be advantageously used in a variety of fields such as viscosity-imparting agent, coating agent, adhesive, formed product, food product, cosmetic, pharmaceutical, and material for agriculture, forestry, stock raising and paper processings, as well as for mining and manufacturing industries.

Abstract: Disclosed is a novel binder which comprises as a main ingredient pullulan and saccharide(s) wherein the weight ratio of said pullulan to saccharide(s) is in the range of 85:15 to 65:35, based on the weight of the dry solid. The binder has a relatively-low viscosity and exerts a satisfiable properties with only a relatively-small amount without a fear of causing an environmental pollution, and because of these it can be advantageously used as a binder in a variety of fields.

Abstract: A radiation sensitized paper having a polyester film, a coating layer which contains a water-soluble or water-dispersible resin and is formed on a surface of the polyester film, a resin layer which is formed on the coating layer and a fluorescent material layer which is formed on the resin layer, in which adhesion of the fluorescent material layer is good.

Abstract: A thermal transfer sheet having a base film, a heat resistant layer which is formed on one surface of the base film by coating a composition which contains (A) a compound having at least two (meth)acryloyl groups and (B) at least one polymer selected from the group consisting of a syrene-alkyl (meth)acrylate copolymer and an .alpha.-methylstyrene-alkyl (meth)acrylate copolymer and cured with an activation energy ray, and heat transfer coloring material layer on the other surface of the base film, which sheet has maintains good runnability and prevents deposition of a thermal head tailings.

Abstract: Disclosed herein is a printed laminate comprising a printed matter and a polyester film having at least on its outer air side a coating layer composed of a water-soluble or water-dispersible resin and a lubricant, said polyester film being laminated on the printing surface of said printed matter.

Abstract: Disclosed herein is a thermal transfer (printing) film comprising:a base film,a stick-preventing layer provided on one side of said base film, said stick-preventing layer being provided at a rate of 0.01 to 1.9 g/m.sup.2 on one side of said base film, the center line average roughness of the surface of said stick-preventing layer being 0.03 to 0.15 .mu.m, the coefficient of parallel slipping of said stick preventive layer against glass surface being not more than 1.0, and the tensile strength of the film formed with said stick-preventing layer on one side thereof being not less than 8 kgf/mm.sup.2 when said film was elongated by 5% in the longitudinal direction, anda heat-melting ink layer provided on the other side of said base film.
