Beschreibung
Zusammenfassung:	PURPOSE:To improve the package strength of a titled element by treating the peripheral part of polyester substrate enclosing a liquid crystal with an alkali, and treating the same with a silane coupling agent, then joining the substrate by means of an org. adhesive. CONSTITUTION:Polyethylene terephthalate has good transparency and resistance to solvent, but has poor adhesive strength. The adhesive strength to peeling thereof can be improved without spoiling the transparency by treating the same with a silane coupling agent after an alkali treatment. In the case of using an org. adhesive of polyester, there is no need for the coupling treatment but in the case of using an org. adhesive of epoxy, silicone or urethane, the effect by the coupling treatment is remarkable. The alkali treatment is accomplished by using an aq. soln. contg. 20% NaOH, treating the substrate for 30sec-5min treatment time at 60-80 deg.C, washing the same in tapping water right after the treatment and drying the substrate.
