Abstract: Provided is an image receptor for a thermal transfer ink, including a plastic film, and a coating layer which is formed on the plastic film and composed of a polyester resin of which glass transition point is 40.degree. to 6.0.degree. C., the amount of the coating layer when dried being 0.08 to 0.8 g/m.sup.2. This image receptor is adaptable for a tape printer and assures good fixing property and fastness of a printed image while exhibiting a satisfactory anti-blocking property when stored. Also provided is a thermal transfer ink sheet for forming a printed image on the image receptor, including a sequential lamination of a foundation, a release layer, a barrier layer composed of a polyester resin, and a colored layer containing 40 to 60% by weight of a polyester resin and 30 to 60% by weight of a coloring agent. This thermal transfer ink sheet is advantageously used to form on the above image receptor a printed image of good fixing property and fastness.

Abstract: This invention relates to the use of a compound of formula ##STR1## wherein X is --CH.sub.2 -- or ##STR2## R.sub.1 is H, C.sub.1-5 -alkyl or benzyl, which can be substituted of unsubstituted; R.sub.2 is H, C.sub.1-4 -alkyl, C.sub.1-4 -alkenyl, OH, or C.sub.1-3 -alkoxy; R.sub.3 is H, CH.sub.3, C.sub.2 CH.sub.3, OCH.sub.3, or Hal; R.sub.4 H, CH.sub.3, C.sub.2 CH.sub.3, OCH.sub.3, or Hal, and Hal is halogen, provided that when R.sub.2 is OH or C.sub.1-3 -alkoxy then X cannot be CO or a non-toxic pharmaceutically acceptable salt thereof for the use in the treatment of age related memory impairment or cognitive disorders, particularly Alzheimer's Disease.
