Release agents for adhesive tapes: Release agents for adhesive tapes. Ashida, Kaneyoshi; Iwatsuki, Hiroyuki; Ohtani, Masaaki; Yoshikoshi, Masahiko (Mitsubishi Chemical Industries Co., Ltd., Japan). Japan. Kokai JP 52024174 23 Feb 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C10M003-26. APPLICATION: JP 75-100939 20 Aug 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Release agents are prepd. from a reaction product of an org. diisocyanate with sugar alcs., glycosides, or sugars partially esterified with C.gtoreq.6 aliph. monocarboxylic acids. Thus, a mixt. of 96.2 g sorbitan tristearate [26658-19-5] and 17.5 g tolylene diisocyanate [26471-62-5] was heated 1 h at 100.degree. to give a solid compd., which was dissolved in PhMe to give a PhMe soln. contg. 26471-62-5 and 37318-31-3 which are cas registry numbers of substances are two of reagents here. 5% of the solid compd. A cellophane tape was coated with the soln. and dried at 70.degree. to give a tape with good release properties. .

Poly(ethylene terephthalate) films for magnetic recording media with thin metal coatings: Poly(ethylene terephthalate) films for magnetic recording media with thin metal coatings. (Teijin Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59045348 A2 14 Mar 1984 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L067-02; C08K005-10. ICA: C08J007-04. APPLICATION: JP 82-155837 9 Sep 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Title films contain 0.001-0.2% sorbitan ester. Thus, poly(ethylene terephthalate) [25038-59-9] was dry blended with 0.001 phr sorbitan tristearate [26658-19-5], formed into a film, biaxially stretched (3.5 times at 90° in the longitudinal and 4.0 times at 105° in the transverse direction), coated with a primer, and heat set at 210° to form a 10-m film which was coated with Ni-Co (Co 80, Ni 10%) by vacuum deposition. The coated film showed significantly decreased oligomer pptn. (which causes surface roughening) and drop out (40 mS/16 dB) at a recording and playback test.
