摘要： PURPOSE: To make it possible to form characters or image with a fusion type thermal transfer printer by forming an image receiving layer for fusion type thermal transfer on the label surface of a recording disk. CONSTITUTION: An ionomer type aq. urethane resin soln. is applied on the label surface of a DRAW type compact disk by using a bar coater and is dried, by which a urethane intermediate film is formed. A coating liquid prepd. by mixing 25 pts.wt. polyvinyl alcohol, 1.5 pts.wt. orthoboric acid and water per 100 pts.wt. alumina sol is applied on this intermediate film by using the bar coater and is dried to form a porous layer of a pseudo baimite type. The label surface of such recording disk is printed with various patterns by a fusion type thermal transfer printer by using a wax based ink ribbon. As a result, the label is inexpensively produced with ease of handling and the indices for the recording contents, etc., of the disk are easily realized.

摘要： PURPOSE:To obtain a recording sheet good in ink absorbability and dye fixing properties and generating no fading during long-term preservation after printing by providing a porous ink receiving layer containing at least one component selected from an ultraviolet absorber, an antioxidant and quencher on a base material. CONSTITUTION:A recording sheet is constituted by providing a porous ink receiving layer containing one or more kinds of a components selected from an ultraviolet absorber, an antioxidant and a quencher on a base material. At this time, the porous ink receiving layer is composed of pseudo-boehmite. The substance contained in the porous ink receiving layer is composed of the mixture of the ultraviolet absorber, the antioxidant and the quencher. Further, the recording sheet is a recording medium for an ink jet printer. The porous ink receiving layer containing one or more kinds of the ultraviolet absorber, the antioxidant and the quencher is provided on the base material and a dye is supported on the porous ink receiving layer to constitute a recording article. By this constitution, the ink absorbability and dye fixing properties are together improved and fading is eliminated.
